Objectives: 1) Reduce or halt erosion occurring at the headcut. 2) Halt the headcut progression which may infringe on and destabilize upstream railroad, highway, interstate, and mine PMT. 3) Halt the headcut progression into the upstream channel morphology and riparian regime. Strategies: • Detailed runoff and flow analysis to the headcut location for the associated 830 square mile drainage area. • Selection of the acceptable design event/peak design flow for the structure. • Determination of all permitting requirements, timeframes, and responsibilities. • Evaluation of the native material stability and excavation [...] (Read More)

  • Coal Creek Stabilization and Sediment Reduction

    Project Synopsis: improved grazing management over the past decade in the lower Coal Creek drainage has resulted in gradual positive trends in riparian habitat conditions. This project will address degraded habitat conditions not directly related to grazing management and build additional trust and cooperation. The Thomas Fork Habitat Management Plan developed cooperatively by WGFD and BLM in 1979 “to preserve, manage, and enhance BCT habitat” identified sediment contribution from the Coal Creek road as an important issue. In 2010, WGFD hired a consultant to develop conceptual plans to address the large amounts of sediment contributed into the stream at eleven (11) key sites along a two (2) mile stretch of Coal Creek. Although the [...] (Read More)

  • Dirtyman Creek Fish Barrier Replacement

    Populations of Colorado River cutthroat trout (CRCT) have experienced dramatic declines throughout their historic range. Current distributions of CRCT are typically limited to isolated headwater streams and lakes. Primary threat to the CRCT is the introduction of non-native salmonids and loss of habitat. A fish barrier on Dirtyman Creek was placed on BLM administered lands to prevent invasion of non-native salmonids and maintain a genetically pure population of Colorado River cutthroat trout. However, the existing structure has degraded over time and needs to be replaced before the integrity of the barrier is lost. The goal of this project is to prevent non-native fish from invading upstream of the existing barrier thus maintaining [...] (Read More)

  • Fish Migration Enhancements on Upper Big Sandy River

    This project will improve fish movements in the Upper Big Sandy River by fish screen and fish passable irrigation diversion replacement. (Read More)

  • Gooseberry Creek Fish Passage Project

    Due to anthropogenic activities and large stochastic events within the drainage, Gooseberry Creek no longer has a population of CRC above a man made Gabion structure. Gooseberry Creek is a small tributary and cannot support a large population of CRC to persist without connectivity to Trout Creek and Sage Creek. When passage is provided through the structures, approximately 1.5 miles of Gooseberry Creek will be available for CRC and other native fish for spawning, rearing and other life history needs. This project is part of an ongoing effort to improve aquatic and riparian habitat within the Greater Little Mountain area to increase the range of the native Colorado River cutthroat (CRC) trout. The Gooseberry Fish Passage Project [...] (Read More)

  • RSFO-Currant Creek Habitat Restoration

    Project Synopsis: the strategy for restoring the habitat on Currant Creek is to permanently exclude unauthorized livestock from the stream and adjacent meadows unless livestock are authorized in the special use pasture. Livestock are only to be permitted to graze every 3rd year for 3 weeks or as approved by authorized officer. (It's been about ten years since grazing has been authorized in the area due to resource concerns.) The most imminent threat to the currant creek habitat is continual cattle drift into the drainage. This results in the unauthorized grazing of riparian vegetation and BLM projects such as willow, aspen, and other woody species plantings. The area is important habitat (ACEC area) for Colorado River cutthroat [...] (Read More)

  • Sweetwater River Restoration (Phase II)

    The restoration project constructed a low level dike, headwall, and head-gate at the mouth of the irrigation ditch to move the river back into its original channel. Phase II– The Sweetwater River jumped into an existing irrigation ditch creating a shortened braided channel (3,200 ft) and dewatering the historic single thread channel of 4,958 ft. The steepened channel created a head-cut in the main channel, causing channel incision and severe bank instability throughout the project area. The restoration project constructed a low level dike, headwall, and head-gate at the mouth of the irrigation ditch to move the river back into its original channel. Project completed August 2008. Approximately 12,100 ft of channel down stream was successfully [...] (Read More)
