This document is a set of aerial maps depicting the Birch Hill Dam facility in the Lower Connecticut River Basin managed by the U.S. Army Corps of Engineers. The maps illustrate four distinct areas of the facility: the main entrance and duck pond area, the dam and upstream habitat, Birch Hill Dam Road, and River Road and Swamp Road. Each map displays the Birch Hill boundary (indicated by red lines), and specifies spraying areas related to a chemical spraying contract for dam spraying and road spraying activities scheduled for 2026.

Figure 1 identifies the entrance road spraying area in light green, located near the main facility entrance. Figure 2 delineates the upstream spray area in yellow, showing the habitat zone upstream of the dam structure itself (shown in white). Figure 3 and Figure 4 both depict road spraying areas in light blue, covering portions of Birch Hill Dam Road and River Road/Swamp Road. The maps provide geographic context and scale measurements in miles to support planning and execution of the chemical spraying contract activities across the specified facility zones in 2026.
