EX DWGS - 26149 Selection of Original 1950s 1960s Drawings SRSGA.pdf

This file contains a collection of original engineering drawings from the 1950s and 1960s related to the Shiawassee River State Game Area in Michigan, submitted in support of contract opportunity 751/26149 for dam safety repairs. The drawings include area maps covering Section 35 and the south half of Section 26 (T11N R3E), cover sheets, and detailed technical drawings of critical infrastructure including an equalizer structure, the Shiawassee River channel configuration, an inverted siphon, and the Pickerel Creek Bridge. These historical documents serve as reference materials for understanding the original design and construction specifications of the dam and associated hydraulic structures that are the subject of the safety repair project.

The drawings represent the foundational design documentation for the Shiawassee State Game Area dam complex and provide essential technical information for contractors bidding on the safety repairs and improvements. As original engineering documents from the mid-twentieth century, these drawings establish the baseline infrastructure conditions and design parameters necessary for developing comprehensive repair and rehabilitation specifications that address current safety standards and regulatory requirements.
