Impaired list (303 d)for Oxygen and
Phosphorus• Total Phosphorus > 0.015 mg/l• Oxygen very low at 10-20 foot
depth in Summer– 3-7 ppm early 1900’s– < 1 ppm today
• Cause: Primarily from non-point pollution and internal loading
TMDL• Total Maximum Daily Load via
Clean Water Act– Maximum amount of Phosphorus
that a body of water can receive while still meeting water quality standards
– TMDL completed by early 2015• 319 funds available to help meet
Phosphorus reduction goals
