About this file
This document provides an overview map and descriptions of vegetation control areas for the Chatfield Reservoir Project in Colorado. The map outlines seven areas totaling approximately 435 acres that require total vegetation control of all rock, roads, and stockpiles. Noxious weed control is also required across all grass areas. Specific areas include the dam embankment (254.9 acres), outlet works channel (21.8 acres), Massey Draw channel (3 acres), spillway (99.5 acres), administration and maintenance area (34.5 acres), Spring Gulch pond (1.8 acres), and Spring Gulch dam (19.6 acres). Special instructions note all-terrain vehicles are prohibited on the dam embankment due to soft, erodible soils, and application methods in that area are limited to backpack or hoses from the top or bottom of the embankment.
The related federal contract opportunity is a solicitation from the U.S. Army Corps of Engineers Omaha District for weed control services at the Tri-Lakes Project Office in Littleton, Colorado. No further details are provided on response dates, award amounts, or other requirements.
