This document is a collection of aerial maps depicting herbicide treatment areas at Lake Isabella, a U.S. Army Corps of Engineers facility in California. The maps identify specific locations where herbicide application is planned or has been conducted across multiple dam structures and associated facilities.

The document presents six detailed aerial photographs with color-coded overlays marking treatment zones: Isabella Main Dam (featuring purple lines indicating treatment boundaries along the dam face and yellow zones on surrounding areas); a Keyesville River Access area with yellow-marked treatment zones near a gauging station; Auxiliary Dam (with purple, yellow, and blue outlined treatment areas); Emergency Spill Way (showing yellow zigzag patterns marking the spillway structure and red boundary lines around operational areas); Headquarters facility (displaying purple, blue, and yellow outlined zones around administrative buildings and parking areas); and Storage Yard (with yellow boundaries delineating the Water Wellhouse and Maintenance Storage Yard areas). Red location markers identify specific reference points including the Main Dam, Gauging Station, Headquarters, and Ponderosa Drive. The maps serve as visual references for vegetation and invasive species management operations across the Lake Isabella project area.
