Book excerpt: Aquatic ecosystems in the western U.S. have been severely degraded over the last century by anthropogenic activities such as mining, logging and grazing. Habitat heterogeneity in streams of the western United States has been lost as a result of both in-stream activities (i.e. dredging and straightening channels) and riparian zone activities (i.e. logging and vegetation removal). A commonly stated objective of stream channel restoration projects is to restore stream habitat quality and thereby improve aquatic species habitat and ultimately increase fish populations. The Ninemile drainage of the Clark Fork River watershed was historically a thriving native Bull trout and Westslope cutthroat trout (WCT) fishery. Intensive mining and logging activities throughout the watershed have severely impaired native fish habitat and reduced fish populations. In 2006, Lolo National Forest partnered with Trout Unlimited to restore a 1.3-mile section of Eustache Creek at the headwaters of the Ninemile drainage. This study used pre and post-restoration habitat and fish sampling data from 2005-2009 to analyze changes in habitat quality and fish abundance in three reaches of Eustache Creek. Habitat quality was assessed using six metrics: width to depth ratio, percent of pool habitat (based on site area), residual pool depth, large woody debris per 100 meters, large woody debris median diameter and percent fine sediment in pool tails. A repeated measures ANOVA model was used to detect significant increases in habitat quality and fish populations over the four-year period in Eustache Creek. A univariate ANOVA model was created to detect significant relationships between individual habitat quality variables and fish populations. Overall, statistical analysis does not necessarily point to a significant increase in habitat quality for Eustache Creek, and the restored stream condition is still far from its reference condition. However, a non-statistical assessment of trends in individual habitat metrics shows an improvement in trout habitat quality. There was a significant increase in total fish densities in Eustache Creek over the study period. Additionally, there was a significant increase in total WCT, Adult WCT, and Adult Eastern Brook trout (EBT) densities over time. However, there was no statistically significant difference in total fish density, total WCT density, adult WCT density, total EBT density and adult EBT density between reference and treatment reaches, indicating that the increased fish populations may reflect the influence of external factors such as climatic variability rather than the improvement in habitat quality. No habitat variables are significantly correlated to total fish density. There was a statistically weak positive correlation between percent pool habitat and total fish density.

Available in PDF, EPUB and Kindle. Book excerpt: Previous research spanning lotic, lentic, and marine environments suggests that habitat enhancement structures (HES) may attract and concentrate fish from adjacent habitats rather than increase fish populations. In addition to concentrating fish, we hypothesized that anglers may target HES, and therefore, that fish concentrated at HES may be more susceptible to angling. To test our hypotheses, we assessed spatial patterns of: 1) habitat structure; 2) fish holding locations; and 3) fishing pressure (i.e., casting patterns) in southwestern Montana stream reaches with HES. Findings suggest that HES aggregate fish and that anglers more successfully target fish holding near artificial HES than similar densities of fish holding further from artificial structures (e.g., near natural holding structures). We conclude that installation of HES may increase angling opportunities, but could also act as fish population sinks by focusing fishing pressure over likely fish holding areas.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Stream restoration has become a popular management tool for attempting to increase and/or restore fish populations by improving habitat. A section of the Strawberry River, Utah recently underwent a stream restoration project, where the main goals of the project included increasing spawning activity, rearing potential, and resident populations of Bear Lake cutthroat trout Oncorhynchus clarkia Utah. The impact of the restoration project on cutthroat trout was investigated by first characterizing preferred habitat for different life stages, investigating habitat as a limiting factor in the system, and then assessing the quality of available habitat by comparing restored/unrestored sections of stream and pre-restoration/post-restoration of the same sections of stream. Results indicated cutthroat trout in the Strawberry River preferred faster water velocities, shallower depths, moderate substrates sizes, and riffle habitat types for spawning. In contrast, juvenile and adult life stages preferred deeper sections of stream, the presence of cover, and pool habitat types. Limiting factor analyses suggested spawner abundance may be limiting in the Strawberry River and maximum daily temperatures during the summer may be the strongest limiting habitat factor for juvenile and resident adult cutthroat trout. Restoration generally appeared to initiate a shift towards more favorable habitat, especially in terms of increasing near-bed velocity and increasing the proportion of preferred substrate sizes for spawning, and increasing the percentage of pools for juvenile and resident adult life stages. The potential benefits of the restoration remained somewhat ambiguous, a result of relatively small differences observed between study reaches, limited pre-restoration data, high spatial and inter-annual variability within and among control study reaches, and the inherently delayed reaction of ecological responses to physical changes from restoration. However, these issues can be resolved through continued monitoring. Long-term monitoring would allow for the accounting of natural variability to further tease out differences resulting from restoration and differences resulting from natural fluctuations. Additional monitoring would also capture long-term responses, which has the potential to be significant considering the relatively slow response of riparian vegetation to restoration. This study also provides a baseline dataset and template for future long-term monitoring efforts.

Available in PDF, EPUB and Kindle. Book excerpt: A beautiful tribute to twenty rivers restored by the work of Trout Unlimited and its members. We all love rivers and the trout that the best of them hold. For fifty years, the volunteers of Trout Unlimited have strived to restore, sustain, and preserve the nation's trout and salmon waters. Weaving together human and natural histories, Ross tells the stories of twenty watersheds where Trout Unlimited has labored to save rivers damaged by human shortsightedness. From Michigan's Au Sable to New York's Delaware to rivers in California, Washington, and more, the stories of these rivers—both in peril and in recovery—will remind fishermen why they love the sound of running water, and why our natural resources need to be protected. 200 color photographs.

Download or read book Rattlesnake Creek Research Project 1986 Final Report Montana USA written by Gary David Blount and published by [email protected]. This book was released on with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Normal 0 The Rattlesnake Creek fishery is unique due to its closure to fishing 45-years ago. Since that time, Rattlesnake Creek has been protected because it supplied Missoula, Montana with municipal water. In 1983, a 25-kilometer section of Rattlesnake Creek above the confluence of Beeskove Creek was opened to catch and release fishing; approximately 12-km immediately below this section remains closed. This study was designed to document the dynamics of an unfished trout population and their response to catch and release angling. The results will provide a point of reference for comparing trout populations in pristine systems with those in heavily impacted and managed streams. Until we understand the structure of undisturbed fisheries and their habitats, our present protection and enhancement efforts will lack both a rational context and effective direction. Objectives for the 1986 study were: 1. Document trout population abundance, size, and species composition, in two unfished sections and two fished sections of Rattlesnake Creek. 2. Evaluate the effects of catch and release fishing on the trout population in Rattlesnake Creek. 3. Document and compare changes in angler catch and pressure on Rattlesnake Creek upstream from Beeskove Creek. 4. Identify early spring and late fall movement patterns of Rattlesnake Creek trout populations. 5. Describe winter habitat used by Westslope Cutthroat Trout. Objectives This one year study was designed to collect baseline data necessary to evaluate the effects of catch and release fishing above Beeskove Creek and the population dynamics of an unfished population of Westslope Cutthroat Trout below Beeskove Creek in western Montana. The objectives for the first year were: 1. Determine wild trout species composition, distribution, size, abundance, and age in four sections of Rattlesnake Creek. 2. Document angler catch and pressure on Rattlesnake Creek upstream of Beeskove Creek. 3. Four sections of Rattlesnake Creek were studied from March, 1985 through February, 1987 to document species composition, distribution, size, and abundance of trout. The effects of catch and release fishing seasonal and diel habitat use were also evaluated. 4. Westslope Cutthroat Trout, Bull Trout, and Brook Trout were present in Rattlesnake Creek. Size and abundance of Westslope Cutthroat Trout and Bull Trout were large compared to other small, relatively infertile streams in western Montana. Catch and release angling (300 anglers per year) had no measurable effect on size and abundance of trout in Rattlesnake Creek. Twenty-one percent of all Westslope Cutthroat Trout tagged were recaptured and 68% of the Westslope Cutthroat Trout over 400-millimeters were caught and released. These and other data collected on Rattlesnake Creek indicate the extreme vulnerability of Westslope Cutthroat Trout to angling. 5. Diel and seasonal changes in Westslope Cutthroat Trout behavior and habitat use were documented. Westslope Cutthroat Trout behavior during late spring days was related to spawning. Feeding was the dominant activity during summer days and cover seeking dominated during winter days. Diel shifts were most noticeable from winter days to winter nights. Twice as many trout were seen at night under harsh winter conditions. Winter night counts correlated well with the summer day counts. Study Area The upper Rattlesnake Creek drainage is located in west central Montana, 8.3-kilometers (5.6-miles.) north of Missoula. The drainage encompasses approximately 21,053 ha (81.3-miles²), and is within the Lolo National Forest. Rattlesnake Creek originates on the flanks of McLeod and Triangle peaks, flowing south-southwest to its confluence with the Clark Fork of the Columbia River at Missoula. The creek descends 1,613-meters (5,291.0-ft) in 37.0-kilometers and has a mean gradient of 4.3%, with a gradient of 1.75% in the study sections (USFS-Lolo, 1976). There are nine perennial tributaries to Rattlesnake Creek. Wrangle, Lake, and High Falls creeks originate from glacial lakes while Porcupine, East Fork of Rattlesnake, Beeskove, Pilcher, Fraser and Spring Creeks originate from springs. More than 40 lakes are located in the upper drainage. The geologic parent material in the area includes argillite, quartzite, and limestone of the Precambrian Belt series as well as Cambrian shales and limestones (Nelson & Dobell 1961). The watershed is characterized by relatively high peak discharge per unit area (Van der Poel 1979). The general topography of the drainage is steep and mountainous. Vegetation varies from a spruce-fir forest in the upper drainage to an open pine-larch forest below Franklin Bridge. Cottonwood trees and shrubs are found in the lower riparian zone and occasionally the valley bottom opens up to small grassy meadows. Rattlesnake Creek is a 3rd order stream with a rubble-gravel bottom and an average annual discharge of 45 to 50-cubic feet per second. The Rattlesnake Creek drainage is managed primarily as a watershed and secondarily as a recreational area (USFS Management Plan 1984). Although Rattlesnake Creek is not currently used as a municipal water supply, plans of building a filtration plant and again using the water municipally are being discussed. A water company dam located 4.0-kilometers upstream from the mouth of Rattlesnake Creek would be the most probable site for a filtration plant. The 12.2-meters high dam prevents all upstream fish migration from the Clark Fork River.

This book was released on 1980 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant changes have occurred in the distribution of trout in streams of Great Smoky Mountains National Park since 1900. By the mid-1970's the original range of the native brook trout had been reduced by about 70% and the species was relegated to suboptimal habitat in head water streams. Most of the stream sections lost by brook trout became the territory of the introduced rainbow trout, which in 1977 occupied about 80% of the Park waters. After 1950, brown trout introduced in State waters outside the Park established reproducing populations in some 50 miles of stream formerly occupied only by rainbow trout. If current trends continue, the recovery of brook trout in Park water may be difficult, if not impossible, and brown trout may occupy much of the territory now held by rainbow trout.
