A video of the webinar, Are Your Ponds Serving Their Water Quality Function, is available for viewing. Sponsored by the City Engineers Association of Minnesota, it looked at stormwater best management practices to retain phosphorous. University of Minnesota researchers John Gulliver and Poornima Natarajan discussed outcomes of the LRRB project, Stormwater Pond Maintenance, and Wetland Management for Phosphorus Retention
A Pond Assessment Tool was developed to identify and evaluate ponds at risk for poor phosphorus water quality and export of phosphorus to receiving water bodies. Data analysis of 230 water bodies and detailed water quality and sediment analysis of 20 ponds formed the basis of the Pond Assessment Tool with statistical analysis of field data and regression models for predicting pond TP, pond anoxia, and sediment release.
The presenters provided recommendations for stormwater pond maintenance and wetland management based on project results and data synthesis of construction and maintenance costs and runoff storage/settling alternatives.
