Region: 4

Project Description:
(Up to 250 words)
This project will treat and enhance approximately 204 acres of open water on Lake Ophelia National Wildlife Refuge by applying herbicide to control the emergent aquatic vegetation. The method of control will consist of applying 2-4,D, labeled for aquatic use, on 204 acres of Lake Ophelia by boat. The mud-boat is outfitted with a spray pumping system that will allow access to the infested areas. The time-fame in which the project will be completed is late summer 2010. The emergent vegetation in the lake has created problems with access to the point that the public have been unable to fish because of the dense vegetation. Refuge Volunteer along with the Refuge Biologist/Refuge Step Students will monitor the lake and map out areas that need treatment. The Refuge Volunteers and Refuge Biologist/Refuge Step Students will perform the control of American lotus ( Lotus lutea), willow trees (Salix spp.), water hyacinth (Eichhornia crassipes), alligator weed ( Alternanthera philoxeroides) and water primrose (Ludwigia spp.) on Lake Ophelia National Wildlife Refuge.

Project Results:
Give an overview of the results of the project. Include quantifiable measure of success, such as maps produced, efficacy of control measures, number of sites where invasions were detected early and responded to, number of community contacts, etc. (Up to 250 words).
The Refuge was able to treat and kill several large floating mats (10-20 acres)in size of water hyacinth/alligator weed. The spray crew also sprayed all around the edges of the lake where we had infestation of water hyacinth. Treating the vegetation will allow for better access through the entire lake. The Refuge was able to treat and restore the entire lake 204 acres in preparation to restock the fisheries and begin plans to reopen the lake for the public to enjoy. Refuge Volunteers/Students and the Louisina Department of Wildlife Fisheries really made this project a succuss through their partnerships.
Number of Acres Treated: 204
