This document is a collection of informational photographs for a sediment removal project at Black Rock Lake in Thomaston, Connecticut, managed by the U.S. Army Corps of Engineers. The photographs provide visual documentation of the project scope and affected areas.

The images depict two primary sediment removal areas around Black Rock Lake, identified with blue outlines on aerial views. Detailed ground-level photographs show sediment removal work at two culvert locations: Culvert 1 (on Mill Branch Road) and Culvert 2 (on Old Branch Road). The photos illustrate sediment accumulation in tributary streams feeding the lake, showing murky water conditions with visible sediment deposits adjacent to and within the permanent pool area near both culverts. Additional photographs document a designated sediment storage area located off Old Branch Road near the Black Rock Lake facility, shown in both ground-level and aerial views. The storage area appears to be an undeveloped parcel of land used for temporary placement of excavated sediment materials. These informational photos serve as reference materials to identify the physical locations and extent of sediment deposits requiring removal as part of the U.S. Army Corps of Engineers' maintenance or restoration project for Black Rock Lake.
