Castleman Creek Watershed Association

This Work Plan for the Castleman Creek Watershed in McLennan County, Texas, outlines a strategy for watershed protection and flood prevention over a five-year installation period. Prepared by the Castleman Creek Watershed Association, McLennan County Commissioners Court, and McLennan County Soil Conservation District, the plan addresses frequent flooding impacting 4,900 acres of bottomland. Key components include the accelerated installation of land treatment measures, seven floodwater retarding structures, 13.56 miles of channel improvement, and special treatment for five critical sediment source areas. The plan aims to significantly reduce flood damage, improve hydrologic conditions, and generate an average annual damage reduction benefit of $98,154, with a benefit-cost ratio of 2.6 to 1 for structural measures. Additionally, it anticipates incidental recreation benefits.
