Home River Initiative being considered by West Denver TU:

By John Snyder
Given our Chapter’s extensive conservation work on Clear Creek, we are now considering a special designation that will accurately reflect a long term stewardship role. Among the conservation roles being considered is the designation of “Home River”. Attaching the label Home River to a favorite flyfishing river seems like an obviously good thing to do. It is appealing because we clearly understand that protecting our homes is perhaps the most fundamental type of stewardship we should perform. But labels should not be taken at face value. People and organizations define Home Rivers differently and the implications of those distinctions are important as WDTU determines its future conservation relationship with Clear Creek. The purposes of this Conservation Corner are to briefly describe the crucial factors affecting Clear Creek’s environmental management; how National Trout Unlimited (NTU) defines its Home Rivers Initiative; and prominent management implications of Home River designation. This information is essential for determining our future conservation relationship with Clear Creek. We also realize that Clear Creek’s water resource use, abuse, and restoration are a complex story that needs to be well understood and thoughtfully considered in order to render any decisions. This information is intended to help with those discussions. The most consistent idea regarding various definitions of Home Rivers is that it includes the entire watershed. All of the lands and tributaries within a water catchment area comprise a Home River region. The dominant environmental feature of the Clear CreekWatershed is that it was declared National Superfund Site under federal CERCLA Law. This classification with all of its associated laws, liabilities and regulations both identifies the magnitude of the environmental restoration challenge and, from a positive perspective, the availability of extensive resources committed to address the problems. This is a balance we need to keep in mind. There are huge resources and alliances in place dedicated to enhancing the Clear Creek Watershed. When WDTU considers Clear Creek it confronts significant challenges and opportunities. Environmental challenges include a severely polluted watershed; continuing development pressures of all sorts; beetle kill and other deforestation impacts; as well as pollutants and sediments from land uses along the I-70 corridor. From the chapter’s perspective, we need to evaluate the several challenges associated with legal requirements, geographic scope, the level of required commitment, and the need for long term commitment. But simultaneously the opportunities are equally significant. There are enormous financial, legal, and political resources and commitments in place to accomplish conservation. This is reinforced by WDTU’s expert knowledge of the watershed, positive working relationships with key stakeholders, and the chapter’s demonstrated history of successful Clear Creek restoration and conservation projects. In 1994 NTU implemented a Home Rivers Initiative program to tackle watershed management challenges. The program now consists of six watersheds located throughout the nation none of which, by the way, is a Superfund Site. Based on positive conversations with the Director of the NTU program Clear Creek would be eligible for inclusion if:
(1) all liability under CERCLA Law is eliminated;
(2) a Good Samaritan legal judgment in favor of TU is on record; and
(3) a full time project director is hired with funding secured for a period of 3 to 5 years.

The existence of Colorado Native Trout in Clear Creek further strengthens NTU’s attraction to the Home Rivers designation. Among the important lessons learned from NTU and discussions with Clear Creek stakeholders are
(1) the need to eliminate all potential liability and
(2) create a comprehensive plan with explicitly stated goals and objectives.
The implementation of a plan that has well defined goals enables the application of best science, the ability to monitor progress, and the capacity to accommodate change. The absence of goals and objectives creates the same dilemma that the Cheshire Cat described to Alice in Wonderland: “If you don’t know where you’re going then any road will take you there”. Regardless of the designation that WDTU assigns to Clear Creek conservation projects, liability cautions and consensus based goals are both prudent and useful. During WDTU’s recent Board meeting four Clear Creek conservation goals and several relevant objectives were suggested. The goals included the Protection of Colorado’s Native Trout Habitat; Restore the Watershed’s Environmental Quality; Improve Access to Quality Fisheries; and Conserve Backcountry Angling Experiences. Information and supplementary materials were supplied to begin this important discussion. It is certain that a rigorous discussion will produce the best conservation projects and elements of a comprehensive plan to assist WDTU’s long term efforts. The issue now is how to proceed. Does WDTU want to commit to a long term TU Home Rivers Initiative? Or perhaps pursue a more opportunistic, short term approach to Clear Creek conservation. We must recognize that both approaches demand diligent liability protection, a conservation plan to achieve WDTU goals, apply the best possible science, and take advantage of the numerous resources in place to restore Clear Creek. If a formal designation of TU Home Rivers is sought, then considerable due diligence is required. But regardless of that formality, it is vital for WDTU members to know that much of that work must be accomplished to responsibly accomplish stream projects within a National Superfund Site.

This is the beginning of an important discussionand we welcome the comments of all WDTU members.

Roan Plateau Oil and Gas Develop Issue

Colorado Trout Unlimited (CTU) is gravely concerned about the BLM Plan's potential impacts on trout, including rare populations of genetically-pure Colorado River cutthroat trout. We are also troubled by the lack of opportunity for public review on the new plan, and by the document's bureaucratic doublespeak, which calls the whole plan's credibility into question. Read about the concerns of Colorado Trout Unlimited's concerns.

Congressmen Salazar and Udall both supported a 'Time Out' for Leasing Roan Plateau for more details visit http://www.saveroanplateau.org/

Upper Colorado River Plagued by Low Flows

Solutions Sought by CTU, Grand County & Colorado River Water Conservancy District

The Upper Colorado River Basin was plagued by low water flows this past fall which led to high temperatures in the river with fish congregating in pools from Granby down to Kremmling. If several ranchers who had senior water rights had decided to use them fully, stretches of the river would have been left bone dry. read article

Oppose the sell-off of Colorado public lands!

Last year, Congress - facing overwhelming opposition from the public including sportsmen and conservationists - rejected a Bush Administration proposal to sell off National Forest lands as a way of generating budget revenue. Like a bad penny, this ill-advised proposal keeps turning up, and is now in the Administration's proposed 2008 federal budget. Read More

Roadless Area Message
Ted Williams has written a detailed message about his view of the Roadless Area issue. I think you will find it informative and interesting. Ted William's Message

- ROADLESS AREA REVIEW COULD AFFECT TROUT IN COLORADO
One of the great benefits of living in Colorado is having abundant wilderness available and Roadless areas within our public lands. These wild places provide so many benefits to the State, serving as a home to an abundant array of wildlife, clean water at the headwaters of our major rivers, and great scenery; one of the things that Colorado is famous for. But all of that may now be threatened as the current Bush Administration is offering States the opportunity to determine how these Roadless areas should be managed...Please read the rest of this article to see how this can affect trout in Colorado. The article includes information of how you can make you desires known to the Department of Wildlife. Most of the threatened Greenback Cutthroat trout habitat is in Roadless areas.

Bark Beetles:

Flyfishers are frequently obsessed with bugs, but there is a strong possibility we are not giving enough attention to the insect causing the greatest impact on Colorado’s coldwater fisheries. Our attempts to match the hatch have perhaps distracted our attention from the extensive destruction of our forests by the Dendronctonos ponderosae---the Mountain Pine Beetle. This voracious little SOB (son of bug) is rapidly decimating Colorado’s forests and, most significantly, the largest amount of that destruction is occurring at the headwaters of our major rivers.
Recent reports published by the U.S. Forest Service predict that every large mature Lodgepole Pine forest in Colorado and southern Wyoming will be dead within three to five years as a result of this unprecedented mountain pine beetle infestation. Lodgepole Pine is not the only species at risk---Limber, Bristelcone, and Ponderosa Pine are also being devoured. In January, 2009, a total of almost 2 million acres of forest were infested, and the annual rate of infestation is enormous. By examples, 500,000 acres were infested in 2007 and another 400,000 in 2008. The fact that most of that loss occurred in counties located at the highest elevations of the State should be a huge concern to both anglers and water resource planners. The headwater forests of the South Platte, Colorado, North Platte, and Arkansas rivers are now fatally damaged. The southwest advance of the insect will inevitably endanger the headwaters of the Rio Grande River. Closer to home, forest scientists estimate that Clear Creek’s Lodgepole Pine forests will be dead within five years and that 27 percent of all its forests will be destroyed by then.
The environmental value at stake is forest cover and the canopy and other environmental functions it serves. The shade provided by forest cover reduces the evaporation of snow pack, the speed and amount of runoff, the depletion of water amounts during summer months, and moderates water temperatures during warm periods. The trees’ nutrients and root systems enhance soil building, promote stability and reduce erosion. Forest cover provides a vegetative regime that offers both food and cover for wildlife that directly enrich the quality of the aquatic habitat. All of these vital functions contribute to the environmental quality of our water and fishery resources.
A lot of publicity associated with the mountain pine beetle’s infestation has rightfully focused on its geographic scope, rapid advance, and potential land use impacts. From the perspectives of forest managers, property owners, and local government officials, the biggest concerns associated with dead forests are wildfire, threats to life and property, further infestation, and visual blight. The Hayman fire’s destruction of property, elimination of forest cover, and contribution to massive sedimentation of the South Platte River exemplifies the magnitude of devastation that can occur. It also epitomizes the difficulty of selecting forest management practices that simultaneously prevent fire and protect coldwater fisheries.
Tree removal is the prevalent solution for reducing the threats caused by pine beetles. At first glance, this solution makes good sense. The cutting and removal of dead trees certainly eliminates fuel for fires, destroys beetles, and reduces blight. From a forest management and property protection standpoint, it is a reasonable approach. There is also strong bi-partisan support for that approach. Many millions of dollars will be expended this year to clear and thin large expanses of dead timber from Colorado forests. But, what about the hydrologic impacts? Clearly, the ecological benefits of forest cover previously described
are also eliminated. We need to recognize that the publicity about the mountain pine beetle’s unprecedented ecological activity and the significant risks associated with wildfire have, unfortunately, overshadowed its potentially
devastating effects on Colorado’s rivers and streams.
The mountain pine beetle has begun a process that is destroying the environmental quality of forests and their beneficial contributions to water resources and aquatic habitat. Timber harvest practices that remove the dead trees will complete that deforestation process. Ultimately, deforestation will affect water quantity, rates of flow, schedule of flows, flood frequency and magnitude, water quality, and water temperature. Obviously, none of the land managers want to harm the hydrologic character of our rivers but, regrettably, their proposed solutions will have that effect unless we insist on mitigation practices. Our mission to conserve coldwater fisheries requires serious engagement on behalf of forest health. Forest management practices such as tree plantings, soil stabilization, and sediment control need to be extensively implemented in order to safeguard Colorado’s coldwater fisheries. Our observations of the hatch should no longer distract us from this reality.

Greenback Cutthroat Trout Recovery Program
may or may not have a setback

A DNA study of the Greenback Populations in state show that 5 of the 9 populations of the Greenback may actually be Colorado River Cutthroat. Back in the late 30's the greenback cutthroat was believed to be extinct. But in the 50's Doctor Benke verified two small populations in a couple of High Mountain streams. The goal of the the program has been to establish 20 naturally reproducing populations of at least 500 fish in each population. Historically Greenback Cutthroats were in over 140 miles of streams on the Front Range. It currently is estimated to be 11 miles of streams. Dr. Benke thinks that the differences in the genetic code that has been identified as being specific to Colorado River Cutts may actually just be a normal variance in genetic code. The only observable differences between Greenback and Colorado River Cutthroats is that one is on the Eastern side of the Continental divide and the other is on the otherside of the Continental divide. The DOW has suspended all Greenback planting operations until more analysis can be completed. The winter 2008, Vol 5 Iss 1, issue of High Country Angler, has two articles about Greenbacks and Colorado River Cutthroat in it. Get a Copy of it and Read the Articles. It's free.

It has been decided that further review of the position TU should take with respect to private vs public access rights. TU's mission is the conservation of cold water fisheries but such activities can cause varied differences of opinion with respect to rights of access when raising funds for projects requiring large donations and/or the need to involve privately held tracks of land.

Water Usage in the United States

"Everyone knows that our population continues to grow. A census count in 1980 identified close to 227 million residents of the United States. Twenty years later, the Census Bureau tallied more than 281 million people here. But did you know that demand for water in the United States declined in 1985 and that it has remained fairly steady since then?" ..... Changes in technology, in our laws, and in our economy, along with increased awareness of the need for water conservation, have resulted in more efficient use of the water from the Nation's rivers, lakes, reservoirs, and aquifers."

Didymo:

Didymo, also known as Rock Snot, (The algae didymosphenia germinate) is believed to be a native algae to Colorado but was a rare occurance in mountain lakes. In 1975 it was first noticed in the Frying Pan River. In the last 10 years, for reasons unknown, it has been expanding its range rapidly in Colorado and other places. It was discovered in the state of Arkansas in 2003, and it is creating more of a stir because it is spreading in the prime trout fishing area downstream of Beaver Lake Dam in Arkansas. Experts are uncertain how to stop the algae's spread. Didymo has now shown up in Tennesse and Virginia. Vermont and New Hampshire, West Virginia now

The single cell diatom, one of the most primitive forms of life, when dead floating down a stream or hanging from branches looks like wet whitish or dirty brown tissue paper. Growing in a river bottom it looks like a thick moss carpet covering rocks. It feels like stringy rough edged slime or wet wool. Didymo can expand into long continuous sheets reaching from bank to bank and extending for miles. The algae isn't known to harm trout directly but there is evidence it interrupts the life cycle of crustaceans which the fish feed on. Didymo also out competes other algea that the crustaceans primarily feeds on. Midges appear to survive. However studies have shown that fish eating the midges have their stomachs full of low nutrient rocksnot along with a few midges. In New Zealand the fish have declinded 75% in two years in some affected rivers. Though it may make the water look putrid the water is actually clean and fresh. Besides potential affecting fish populations it is known to clog water intakes. The largest algae blooms appear to happen in water depths of 6 ft or less with stable flows, open sunny streams below reservoirs and lakes.

How it is jumping from river to river is unknown but fisherman and other river enthusiast are believed to be the major culprit though. Recent test in New Zealand has shown that the algae can live 40 days out of the water. Fisherman need to help prevent the spread by cleaning their wading equipment after leaving a body of water and before entering another.

Colorado streams reported as now having Didymo:

Arkansas River
Blue River
Cache La Poudre
Castle creek - Elk Mountains
Colorado River Head waters
Copper Creek - Elk Mountains
Chihuahua Gulch
Eagle River
East River - Crested Butte
other numerous Creeks around Crested Butte

Peru Creek
Piney River
St. Vrain

Report any siting of Didymo to the EPA at 303-312-6212 or spaulding.sara@epa.gov

Didymo is indigenous to Colorado but it is an invasive species affecting New Zealand. New Zealand Biosecurity is taking dramatic steps to control invasive species entering their country. One of those steps is that you are required to sanitize your wading equipment at the airport upon entering the country.

Whirling Disease:

Whirling disease has had enormous impacts on the rainbows in Colorado Rivers. Wild trout reproduction has been severely impacted by its presence. Most of the trout waters in lower Colorado elevations now have Whirling Disease in the system. The few populations of native trout such as the Colorado River Cutthroat, Rio Grand Cutthroats and Greenback cutthroats located in high Mountain Streams and lakes are at risk of being affected. Anglers visit our high mountain streams and lakes need to sanitize their wading equipment before hiking into the mountains.

Eurasian Water-Milfoil

The Eurasian water-milfoil (Myriophyllum spicatum) is a submerged, rooted perennial plant consisting of long underwater stems with finely-divided leaves floating near the surface. The species can occur in high abundance and replace native plant species. Rapid colonization can result not only in the disruption of native plant communities but also can change substrates, flow patterns, and invertebrate communities. Subsequent impacts to fish populations are poorly known. The species has been documented in all states except Montana, Wyoming, Alaska and Hawaii. Road checks in Minnesota found aquatic plants on 23% of all watercraft inspected. Read More - see pictures.

Eurasian watermilfoil (EWM) is an invasive species in the Front Range and has been found from St. Vrain State Park in Longmont south to Chatfield State Park in Littleton. It is known to be in Boulder, Jefferson, Denver and Weld Counties.

Zebra Mussels -

Jan 19, 2008 - "Recent sampling efforts between the Colorado Division of Wildlife (DOW) and Colorado State Parks personnel detected the presence zebra mussels at Lake Pueblo State Park. Two adult mussels and one immature specimen were found on substrate sampling gear, and the larva (veliger) was found by performing plankton tows. Jan 2008" Read the press release.

The zebra mussel poses a huge threat to the west. An invasive freshwater bivalve native to Russia, this species was first discovered in the Great Lakes in the late 1980's and has since spread to more than 20 states. This nuisance species has already caused billions of dollars worth of economic damage within the Great Lakes region alone. Nationwide expenditures to control zebra mussels in water intake pipes, water filtration equipment, and electric generating plants are estimated at $3.1 billion over 10 years. Zebra mussels can clog pipes by forming colonies inside of the pipes. Then the water cannot flow through the pipes as easily.

The westward spread of the zebra mussel could have a devastating effect on our economy and ecosystems. The mussels have been spotted on trailered boats, from more eastern states, in numerous locations in western states (Including OUR FRONT RANGE) but the mussels have not spread west of the 100th meridian. It is important that when a boat is brought from some where further east than Colorado that the Live wells are flushed with bleach solution. The water cooling systems needs to be inspected and flushed with bleach. Nebraska South Dakota, Kansas and Okalhoma are the nearest places that they have been found; so far. All of which have large numbers of people migrating to Colorado or at least visiting.

Zebra mussels look like small clams with a D-shaped shell. Usually the shell is yellowish-brown with alternating dark and light stripes and is usually less than an inch long .Using sticky byssal threads they attach fast to any hard surface. Zebra mussel larvae ) are about the diameter of a human hair and are so small you can't see them without a microscope. The larvae floats in a water column for 1-5 weeks. As it grows it begins to sinks searching for a hard surface to attach to.

Quagga Mussel

Until recently they were known to only inhabit the Great Lakes. The Quagga Mussel, an invasive species in the US, is native to the Caspian Sea. Appearance - is white to tan fan shaped mollusk with dark narrow stripes. It has point edges at either side; see picture above that shows a Quagga and Zebra Mussel. Until last 2007 it was believed Quagga and zebra mussels were not present in any waters west of the 100th Meridian. But one or both have now been found in several reservoirs on the Colorado River in California, Nevada and Arizona. They now known to be in reservoirs here in Colorado.

Quagga Mussels discovered in Lake Granby in Colorado

In July 2008 DNA testing confirms that Quagga Mussel vilger, new born mussels, are living in Lake Granby located just west of Rocky Mountain National Park. Inspection programs for boats. The DOW is working on plans for doing boat inspections and requiring sanitation certificates. The plans probably will involve inspections at other high use reservoirs that are also water sources for cities and towns. The legislature has allocated funds for inspectors.

Lake Granby, Shadow Mountain Res, Willow Creek Res, Tarryall Res, Jumbo Res and Pueblo Res all have recently been confimed to have Quagga Mussels and/or Zebra Mussels

The Quagga Mussel (Dreissena bugensis) is bigger than the Zebra Mussel (Dreissena polymorpha). Both were first found in the Great Lakes. Quagga mussels do not cling to substrates as tenaciously as the zebra mussel. Though expanding it's range in the US Quagga mussels are established in a lot less locations than the Zebra Mussel. The thumb nail size Quagga Mussels can live in any type of water: clean, brackish, cold, warm, deep or shallow. Appearance is white to tan with a fan shaped shell that has dark narrow stripes. It has pointed edges at either side; see picture above. The mussel filters pollutants out of the water so that toxins end up building up in their bodies. Some fish such as yellow Perch find them very tasty so in turn the toxins build up in the perch. As with other invasives their presence then competes for food resources with native plants and animals. Like Zebra Mussels they can cling to any hard surface causing significant maintenance cost impacts at power plants, marinas and boats by clogging water piping systems. They will cling to hulls, tanks and sumps. There are a number of lakes in San Diego county California where you now can not take you personal water craft or float tube due to Quagga mussels being found in a few of their reservoirs around San Diego.

Rudd

Rudd (Scardinius erythrophthalmus) is a member of the minnow family and is native to western Europe. Rudd tolerate a wide variety of conditions and have been found in a number of habitats from subalpine lakes to large rivers and small streams. They are reported to feed mostly on aquatic invertebrates but also can switch to plant foods. In at least certain habitats, Rudd can live up to 30 years. The species has been widely reported in Colorado but we do not know whether populations are established there or not. Commonly brought into the state in bait buckets. more info

Bait Import Restrictions -
Never thought about issues with bait before but after reading this I see where it can become a big problem - N.D. Bait transport restricts across state lines
I don't know what the restrictions are here in Colorado. But the recommendations from the protect your waters website says to not bring bait from other locations to a body of water, Do not release bait back into the water, dispose of it in on land.
