Prairie View Golf Course Pond Modification
Lake Okabena does not meet state water quality standards due to high phosphorus levels. The Total Daily Maximum Load Study identified a 70% reduction in phosphorus from the watershed is needed to meet water quality standards. The City of Worthington owns the recently closed Prairie View Golf Course. Okabena Creek flows through the golf course and some small ponds. This project will modify these three ponds to increase storage and removal efficiency, and add an iron-enhanced filter bench to enhance soluble phosphorus removal. These modifications will an estimated 945 pounds of phosphorus annually, accomplishing about 30 percent of the total watershed load reduction needed.
