21 | P a g e vegetation and tree clearing, along with the addition and repair of fishing piers will greatly improve access. Additionally, the sportfish population could be improved with the chemical renovation of the existing fisheries. Goals: Habitat, Prevention, Access Tasks: a. Improve shoreline angler access by repairing existing fishing piers and adding bump-outs or floating docks. b. Chemical renovation of fish population to improve sportfish populations. c. Improve aquatic habitat with shoreline reshaping and selective deepening. Ownership: NGPC Potential Partners: NGPC Parks Division, Fort Kearny Expo Committee Harlan County Reservoir (Harlan County) At 13,500 acres, Harlan County is Nebraska's second largest reservoir and is owned and operated by the US Army Corps of Engineers for flood control and irrigation. Shoreline erosion and lateral transport of sediments have reduced available aquatic habitat and connectivity of 10 major coves to the main reservoir. A COE 1135 project, completed in 2024, restored Methodist Cove and experiences learned from that project could be applied to these other coves. While evaluating the protection of the cove habitat, identify areas to enhance angler access which are limited throughout the reservoir. Expansion of confined animal feeding operations and intensive row crop agriculture in the Republican River and Prairie Dog Creek watersheds have increased transportation of sediment and nutrient contributing to harmful algal blooms. Evaluate possible solutions to reduce sediment and nutrient inputs and protect water quality within the reservoir. Goals: Habitat, Access, Evaluation Tasks: a. Enhance habitat conditions by restoring connectivity of coves for shoreline- oriented species such as crappie. b. Improve littoral habitat by protecting select areas of shoreline around the reservoir to prevent future erosion and in-lake sediment transfer. c. Protect water quality and reduce sediment and nutrient inputs by constructing wetland and sediment dikes in the upper end of Prairie Dog Cove. d. Enhance in-lake fish habitat using cedar trees and artificial structures. e. Evaluate effectiveness of cedar tree and artificial habitat placed in Methodist Cove. f. Improve shoreline access with bump outs, jetties and docks. Ownership: U.S. Army Corps of Engineers Potential Partners: U.S. Army Corps of Engineers.
