Entered, delineated, and approximate modeling parameters. North: 12,000 sq-ft average footprint; 3 ft depth = 36,000 cu-ft South: 8,500 sq-ft average footprint; 3 ft depth = 25,500 cu-ft Total: 20,500 sq-ft average footprint; 3 ft depth = 61,500 cu-ft Entered as 40,000 cu-ft permanent pool and 21,500 cu-ft water quality detention. This ensures that most dry weather flow is treated. Simulated wet weather benefits would be negligible. This is the Dairy Fork Wetland, was renamed in OCST at some point.
