11/14/2022 0 Comments Beaver lake project office![]() Increased education and awareness to over 20,000 stakeholders in the Beaver Lake watershed.ĩ. areas with no habitat, use of habitat structures by anglers, angler information on fishing the structures with a creel survey.Ĩ. Evaluation and survey data on fish habitat improvements, including comparisons on fish use of new habitat structures vs. Improved shoreline and weekend angler success by placement of 30 fish habitat structures close to public access areas and shoreline fishing locations and improved angler catch rates and satisfaction rates.ħ. Improved fish habitat in Beaver Lake with added 130 habitat sites.Ħ. Improved water quality in Beaver Lake (that is used for drinking water for over 500,000 people).ĥ. Local demonstration site for landowners to visit to learn more on stream restoration.Ĥ. Six acres of riparian buffer enhanced with Ozark native plants.ģ. 600 linear feet of streambank and stream channel restored along Big Clifty Creek.Ģ. Habitat placement goals include 130 new fish habitat sites on Beaver Lake, thirty sites will be located close to public use areas to improve shoreline angling success and increase access to underserved community groups.ġ. The trees will be placed in Beaver Lake to improve fish habitat around the lake. Removal of the trees will correspond with a prescribed burn schedule to improve plant diversity and wildlife habitat. The goals of the Beaver Lake Cedar Tree Habitat Project will be to improve fish, wildlife and glade habitats on Beaver Lake, and Beaver Lake Wildlife Management Area (WMA) by removing invasive Eastern Red Cedar trees from several areas around the lake. A Stream Channel and Riparian Stabilization Project will implement best management practices to achieve nutrient and sediment reductions, and will be installed along Clifty Creek, a tributary of War Eagle Creek, and within close proximity of Beaver Lake. War Eagle Creek is also listed by the Arkansas Division of Environmental Quality as an impaired stream due to increased siltation and nutrients. The War Eagle Creek subwatershed is predicted to deliver the largest nitrogen load under both existing and future scenarios (See Figures 3 and 4). As with sediment, the Beaver Lake and War Eagle Creek subwatersheds are predicted to be the largest sources of phosphorus to the lake. By 2055, the total phosphorus in the lake is expected to increase by approximately 24,000 pounds per year. Without additional protective measures, stream channel erosion is estimated to contribute most (approximately 60 percent) of the sediment load to Beaver Lake. According to the Beaver Lake Watershed Protection Strategy future annual sediment loading is estimated to increase 21 percent or almost 50,000 tons per year. Increased siltation, excessive nutrients, and lack of littoral structure are priority impairments identified in the Southern Appalachians region. This fertility gradient is a function of the high retention time (1.5 year’s average) of water in the reservoir working in combination with varying inflows of nutrients and sediment into the reservoir.īeaver Lake is an aging reservoir, it is over 53 years old and fish habitat is degrading over time. The fertility of Beaver Lake varies from being extremely fertile in the upper reaches of the tributary arms to being relatively infertile in the lower areas around the dam. Historically, standing timber was abundant in some coves, but is now deteriorating as the lake ages. Shoreline habitat varies from shallow sloping mud flats, moderately sloping gravel and cobble banks, to sheer vertical limestone and sandstone cliffs with large rockslides. ![]()
