EPA Region IV r, ,.... CD o C.il ill Lake Tholocco, Alabama: This recreational lake, used by more than 100,000 people each year, was frequently closed to contact recreation in 1979 because of bacterial contamination from animal waste. Aggressive promotion at the local level combined with good farm planning has resulted in the treatment of 8 of 20 swine operations, despite a depressed economy in the area. ~. 11II Taylor Creek-Nubbin Slough, Florida: This watershed COntributed about 30 percent of the phosphorus loading in only 4 percent of the inflow to the highly.valued, but eutrophic, Lake Okeechobee; This large, shallow lake provides water for 5 towns, and supports a $6 million commercial fishery and a sport fishing industry worth another $20 million annually. .Im- plementation of BMPs on the many dairy and cattle farms in the 11 0,000- acre project area has been extremely active, because of technical assistance and cost-sharing (including supplemental state funds) in the , , presence of regulatory pressures. Final project analyses probably wl/l.be able to document that RCWP implementation reduced phosphorus load- ing. II! Lower Kissimmee River, Florida: This river basin delivers 20,percent of the total phosphorus and 25 percent of the total nitrogen io Lake Okeechobee. Phosphorus sources are nutrient runoff (manure and fer- tilizer) from pastures and direct manure deposits by cattle in streams and ditches. Based upon what was learned in the Taylor Creek-Nubbin Slough project, this new RCWP began in 1987 with a "nutrient mass balance' ap- proach to dairy farm management. In essence, on large dairy farms all nutrients are to be recycled. Shaded feeding areas provide an alternative tq cooling olf In the stream, keeping cattle away from stre~ms. 14
