Project Title: Emergent Aquatic Weed Control on Lake Ophelia NWR
Region: 4

Project Description:
(Up to 250 words)
This project will enhance approximately 150 acres of open water lakes on Lake Ophelia National Wildlife Refuge by spraying the herbicide Aqua-Net to control the emergent aquatic vegetation. The method of control will be applying a Glyphosate product, (Aqua Neat), labeled for aquatic use, on 150 acres of Lake Ophelia NWR by boat. The boat is outfitted with a spray pumping system that will allow access to the infested areas. The emergent vegetation in the lakes has created problems with access to the point that the public have been unable to hunt and fish because of the dense vegetation.

This project has captured the interest of surrounding landowners and refuge users on just how important it is to control invasive species within these small lakes on Lake Ophelia NWR.


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).
Approximately 150 acres of infested aquatic weeds were mapped out and treated. The treatment have greatly helped with the control of invasive species in these lakes, but in FY 09 the refuge plans on visiting these lakes again to treat areas that were missed in 08.
Number of Acres Treated: 150 acres
Number of Acres Inventoried and/or Mapped: 150 acres
Number of Acres Restored: 100 acres


Budget: Account for funds in broad categories such as equipment, volunteer stipends, travel, coordinator salary/contract, etc.

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
This program was very useful in meeting the objectives of this project. Five thousand dollars seems like a small amount of money when dealing with invasive species projects but it's surprising how much work is completed with the help of refuge volunteers.
