The City of Chanhassen has approximately 250 publically owned stormwater ponds across the City. A stormwater pond is a common type of stormwater management Best Management Practice (BMP) that is used for rate control, flood mitigation and water quality treatment. In the summer of 2020, city field staff conducted comprehensive bathymetric surveys and visual condition surveys on nearly all 250 ponds. The purpose of these surveys was to obtain quantitative data on the condition of the City’s ponds, and to use this data to prioritize which of the City’s ponds need maintenance. Pond maintenance is crucial to ensuring healthy stormwater infrastructure in the City, and to protect downstream water bodies and natural resources.
