This document is a set of detail plans for Structure No. 1, a flood protection and water control structure on the Middle Fork of Anderson River Watershed in Perry and Crawford Counties, Indiana. The project was developed in cooperation with the Perry County Soil and Water Conservation District, Crawford County Soil and Water Conservation District, and Middle Fork Watershed Conservancy District under the U.S. Department of Agriculture Soil Conservation Service.

The plans include comprehensive engineering drawings and specifications for a concrete and steel structure designed for watershed protection and flood prevention. Key components include a principal spillway with emergency spillway capacity, a gated intake structure for water control, reinforced concrete pipe conduits, an antiseep collar and gasket-type joint system, and detailed foundation work with concrete bedding and steel reinforcement. The structure incorporates multiple design features including a drain inlet system, bell wall fitting, slide headgate, and provisions for perforated pipe drainage. Plans specify soil moisture-density relationships, boring logs, cross-sections of various structural elements, and standard construction details. Material specifications include concrete Class 400/3400 entraining, steel bar reinforcement, corrugated metal pipe, and various hardware components. The drawings reference multiple bench marks, elevation data, and construction staging sequences. Document revision dates and Form SCS 313 (November 1965) indicate the plans were finalized in the mid-1960s as part of a cooperative federal-state watershed protection initiative.
