In a cooperative effort between the Sweetwater County Wildlife Association and BLM, improvements were made on the lower section of Bone Draw. Fish pool areas were developed by placing log water drops in the channel, and fencing was done to exclude livestock from the seep area. In addition, fish eggs were placed in some of the pool areas. These improvements were installed after 1980. Reports indicate that fish have returned to spawn in Bone Draw since the original placement. Two major reservoirs exist within the project withdrawal area. They are the Eden Reservoir and the Big Sandy Reservoir and both provide game fisheries habitat. The Eden and Big Sandy Reservoirs are major irrigation water storage reservoirs for the Eden Irrigation Project. The former is a relatively shallow reservoir (15 feet) which may winterkill. Fish common to both the Big and Little Sandy Rivers are present in the reservoirs. The Big Sandy Reservoir maintains a population of brown trout and contains a small number of cutthroat trout. Rainbow trout occur incidentally in the reservoir. The wildlife in the watershed is primarily a composite of native terrestrial animal communities that depend upon specific vegetative types or other animals in the community for food. Some of these animals are closely tied to a particular plant community or vegetative type while others range throughout the study area and adjacent areas. Many animal species may be found in the study area throughout the year, while some migrate into the study area for certain seasons of the year. Pronghorn antelope, mule deer, elk, and moose are the major big game species found in the watershed. The Wyoming Game and Fish Department currently manages the population of these species on a hunt area-herd unit basis. Antelope and mule deer are common sights in and near the irrigated lands. The sage grouse is the predominant and most important game bird inhabiting the watershed. Actual numbers of sage grouse are not known. The sagebrush-grass vegetation is characteristically occupied by sage grouse. This type of vegetation covers much of the study area that is not irrigated. Sage grouse use the irrigated lands extensively for brood rearing. The project area is part of the Pacific Flyway. Important habitat for ducks consists of nesting, brood rearing, and resting areas used during the spring, summer, and fall. These include flowing waters such as Pacific and Jack Morrow Creeks, the Little Sandy and Big Sandy Rivers, stock ponds, reservoirs, and irrigation induced wetlands in the project area. Figure 2 shows the location, types, and size of wetlands in the project area. Table 2 shows the wetland inventory by type and water source. Population estimates are sketchy. Most ducks do not reside in the project area yearlong since the winters are cold enough to freeze flowing waters as well as standing waters. Commonly observed ducks in the project area include mallard, pintail, shoveler, American widgeon, gadwall, teal, ringnecked duck, and redhead. The Canadian goose is also commonly seen in the project area. O:JL 5', 7
