Conduct a comprehensive visual vegetation survey of Elisha’s Pond to document pre-treatment conditions. 2. Samples of water to be collected from at least 2 points of the pond to establish a base line from which future treatment and testing can be measured. 3. Vegetation survey to include 4 monitoring areas, (5 samples at each) to evaluate Hydrilla and native (non- target) plant species. 15 Tuber samples will be gathered (5 each, within areas 1, 2, & 3 (Excluding area 4 where water is deepest). 1. Mobilization of all personnel and equipment. 2. Purchase and delivery of all materials to complete the project. 3. Use of Sonar One at labeled application rates. The average depth of Elisha's pond is estimated to be approximately 10'. 4. Sonar One to be applied at 20 ppb (parts per billion) using a broadcast pelletized formula applied to the entire pond. This rate will allow multiple treatment to be performed in a single season. Sonar One is a controlled release formula vs Sonar SPR or Sonar Q which are "quick release and less targeted" as the 20 ppb is near the lowest end of the application spectrum.

Initial Sonar One treatment to be performed from jon boat with electric motor (not to exceed 6 horsepower) calibrating a pelletized spreader to evenly distribute the treatment across the entire pond. 6. Access of the pond to be from Camp area carrying the boat down to the water and hauling it out upon completion. 7. Clean up of project area(s) after completion including cleaning of the jon boat following General Prevention Procedures for Stopping Aquatic Hitchhikers by ProtectYourWaters.net. 1. Two (2) weeks after performing the initial treatment, samples of water to be collected from at least 2 points of the pond to ensure the active ingredient is adequate and desirable treatment levels. 2. Water samples to be collected via canoe/kayak and/or paddleboard to access target areas. All samples will be kept on ice and sent in to the lab for analysis. NOTE: Final Second treatment amount is dependent on these results to ensure that we are getting the desired ppb in the pond for efficient Hydrilla treatment. 1. Mobilization of all personnel and equipment. 2. Purchase and delivery of all materials to complete the project. 3. Use of Sonar One at labeled application rates. The average depth of Elisha's pond is estimated to be approximately 10'. 4. Sonar One to be applied at approximately 15ppb using a broadcast pelletized formula applied to the entire pond to maintain ppb. 5. Sonar One treatment to be performed from jon boat with electric motor (not to exceed 6 horsepower) calibrating a pelletized spreader to evenly distribute the treatment across the entire pond. 6.

Water samples to be collected via canoe/kayak and/or paddleboard to access target areas. All samples will be kept on ice and sent in to the lab for analysis. NOTE: Second treatment amount is partially dependent on these results to ensure that we are getting the desired ppb in the pond for efficient Hydrilla treatment. 1.
