About this file

This document is a Vegetation Control Plan for the William L. Jess Dam, dated 12 April 2012. The plan details a comprehensive vegetation management strategy with three priority levels of control areas: 1) High Priority - Dam Structure, Abutments, Toe, Survey Lines of Sight, and Instruments, 2) Medium Priority - Spillway Channel, Regulation Outlet Structure, Upper Tailrace Area, and 3) Low Priority - Lower Tailrace Area and Areas Upstream of Dam. The map clearly delineates different vegetation zones, including vegetation-free zones (grass only), vegetation maintenance areas (grass and brush only, no trees), and multiple survey lines of sight control areas. The plan provides detailed geographic mapping with specific zone markings, measurement scales, and precise area demarcations to guide vegetation management efforts, ensuring clear visibility, structural integrity, and operational safety of the dam infrastructure.
