Description | Work involves application of Cutrine Ultra or Copper Sulfate in Lake Mohegan as an aqueous solution by a licensed contractor approved for aqueous pesticide applications in New York State. A maximum of one-half of the lake (approximately 51 acres) would be treated per application to minimize the effect on the fish and other lake fauna. The treatments would be sprayed into the water from a boat. There will be no application within 100 feet of the state designated wetlands at the south and north ends of the lake, or within 100 feet of the outflow area in the north end. Cutrine Ultra (Pesticide EPA Registration Number 8959-53) has an active ingredient in a 27.8% concentration of Copper Ethanolamine Complex, Mixed. The application rate for Cutrine Ultra would be .6gallons/acre foot with a maximum treated depth of the top 6 feet. The dosage rate for Cutrine Ultra is designed to ensure a concentration of no more than .2 ppm in the upper 6 feet of the lake. Each treatment would cover 51 surface acres and 306 acre feet. This would involve a dosing in a single application of 183.6 gallons of Cutrine Ultra, and a total annual dosage if all 8 treatments are performed of 1,468.8. gallons. | ||||
