This is a technical engineering drawing from the Department of the Army Corps of Engineers showing detailed architectural plans for Baldhill Dam's Stage No. 2 Spillway, specifically focusing on Piers Nos. 2 and 3 masonry. The drawing includes multiple views: a Section A-A showing anchor bolt setting for trunnion anchorage, a plan view, downstream elevation, main elevation, and upstream elevation views of the spillway structure.

The drawing contains precise measurements and specifications for various components including concrete structures, copper water stops, anchor bolts, and chamber details. It shows detailed cross-sections with elevations marked and includes technical notes about water pressure joints and trunnion bearings. The scale is noted as "SCALE IN FEET" and the drawing appears to be from an original engineering document that would be used for construction or renovation work on the dam's spillway system. This technical drawing aligns with the scope of work described in solicitation W912ES25B0001 for repairs to Baldhill Dam, particularly regarding the concrete and structural elements that require rehabilitation.
