i i a LaBarge Creek Rehabilitation WGFD S-FC-CU-WG020 $5,800 As part of a larger watershed improvement plan in conjunction with the Bridger- Teton National Forest, WY Game and Fish Dept. has installed aquatic habitat enhancement features on a reach of LaBarge Creek at the Bald Hornet Station. The reach will serve as a test section in which to monitor the effectiveness of habitat improvements over time. Seven locations, over about 0.3 miles of the creek, received bank stabilization by rock and tree revetments, instream rock weirs in both "V" and diagonal configurations, and excavated pools to break up imbeddiness of the substrate. In addition, a wetland was constructed to catch sediment laden runoff from a nearby uplands. Macro-invertebrates were sampled at various locations in LaBarge Creek above and below the Bald Hornet Station. As these and various other sediment reduction practices are attempted in the watershed, invertebrate populations should indicate if sediment is being reduced by the increased proportion of sediment intolerant species. Cutthroat trout spawning success and young-of-year habitat development will also be evaluated. Muddy Creek Habitat Enhancement WGFD S-FC-CU-WG030 $30,000 ~ Muddy Creek, a deeply incised creek, needs extensive rehabilitation and habitat ~ improvements before it can contribute to Colorado River cutthroat trout restoration as planned in the Little Snake River drainage. Wyoming Game and ~ Fish Dept. installed 11 sheet piling structures using PVC panels. Panels were ~ driven into the sediments to the desired depth, then supported by rock rip-rap. . At the deeper incised locations, rock plunges were installed on the downstream face of the sheet piling. The project increased pool habitat and wintering habitat ~ for fish, raised the water table to enhance riparian vegetation growth, stabilized ~ Muddy Creek banks, and reduced stream velocities that are currently too high for • trout. Use of PVC sheet piles is a departure from the typical rock and soil materials usually used for these structures. Wyoming GFD concluded that while ~ initial materials costs are higher, labor costs are much lower for installation of ! these structures as compared to the usual rock weir structures. ~ Killdeer Wetlands ~ BLM 5-FC-CU-WG040 $51,200 ~ With partnership assistance from the City of Green River, WY and a private non- • profit local task force, BLM constructed a wetland complex featuring a main pond of 44 acres (maximum depth 5.7 feet) containing seven constructed waterfowl ~ nesting islands. A headgate and water supply ditch provide a direct diversion ~ from the Green River. A water control structure is installed in the main dam to • regulate the water level in the pond and to return flows to the Green River. A • gravel-lined, meander outflow channel below the dam was funded by Trout r~~a ~~ H H V
