Lake Lawrence Aquatic Weed Harvesting
The purpose of this page is to provide a general overview of the Lake Lawrence Management Districts Harvesting Program. It provides a general overview of pertinent information and the recommended procedures for the programs operations: harvesting schedule and strategy, off-loading sites, and disposal sites. Program objectives are to: 1) Mechanically harvest and remove at least 90% of the aquatic plant material from the harvest areas designated by the steering committee. Ultimately lake quality objectives underlying the harvesting program are the enhancement of summer navigation and water contact recreation and the prevention of fall algal blooms (which utilize nutrients from decaying plant material) . 2) Dispose of the harvested plant material in an environmentally acceptable and productive manner at locations of minimal transport distance from the lake. 3) Maintain a minimal disturbance or inconvenience to shoreline area residents and lake users.
The Washington State Department of Fish and Wildlife advocates that aquatic vegetation management programs allow areas to remain intact as wildlife habitat. Several areas have been designated as conservancy areas. These areas do not hinder shoreline residential access to open water areas and are considered to be valuable areas for fish spawning, wildlife and immature fish shelter, and waterfowl food.
These areas will not be harvested during the early stage of the harvesting season when fish spawning and larval fish development occur. The harvesting plan therefore recommends bypassing conservancy areas on the first lake harvesting or until late July which ever occurs later.
Historically two harvests occur on Lake Lawrence each year removing approximately 50 - 60 acres of plants. These harvests typically target the holiday weekends. The fist occurs prior to the July 4th weekend and the second harvest prior to Labor Day.
