Huron River

The Huron River is the central natural feature of the City. Its channels, ponds, flow, floodplains and terraces, dams, fish and animal habitats, and the hills and moraines down through which it has cut, comprise its character. It transports water and sediment, it stores and moves floodwaters, and it is the major source of drinking water for the City. Associated with the river are tributaries, wetlands and meadows, and the City's most significant topography.

The long-term vision for the river is to continue to restore the water quality of the River and its tributaries, making them once again rich in wildlife, and appealing for swimming, water sports, fishing, and for more pleasant recreation of all sorts.


What the City of Ann Arbor is doing

  • Phosphorus Ordinance - By limiting the unnecessary application of phosphorus to lawns, the City can reduce the amount of phosphorus into the river by a significant 22 percent.
  • Huron River Watershed Plan -The Watershed Plan for the Huron River in the Ann Arbor – Ypsilanti Metropolitan Area, was written in 1994 and last updated in 2008 by the Washtenaw County Water Resources Commissioner and the Huron River Wateshed Council, provides a long-term strategy to preserve and protect the County’s most prominent waterway.
  • Huron River and Impoundment Management Plan - A committee met from 2007-2009 to develop management recommendations for the Huron River, including strategies for maintaining the ecological balance and providing sustainable recreation opportunities.
  • Source Water Protection Plan - The City has completed a source water protection assessment for both the surface water and groundwater drinking water sources. Results were based on the geologic formations, water chemistry, and number and type of potential contaminant courses located within the source water protection area. A summary and explanation of our results can be found in our annual water quality report. The City will develop and implement a source water protection plan based on the results of the source water assessment.
  • Huron River aquatic vegetation study - This study presents a preliminary review of aquatic plant management alternatives for Barton, Argo, Geddes, and South Ponds, all of which are impoundments of the Huron River.
