​Rivers, creeks and trees​​

The Huron River is Ann Arbor's most important natural feature. It provides 85% of the city's ​drinking water, along with valued recreational opportunities and quality of life benefits for residents and visitors alike.​

The water resources team works to a​chieve the city's water quality goals related to source water (surface and ground), drinking water, wastewater, and stormwater​. ​

The City of Ann Arbor has:

  • Over 540 miles of storm​water conveyance system
  • Over 23,000 inlets and catch basins​
  • Over 43,000 street trees​
  • Over 6,000 park trees​

The urban forest​

The urban and community forest provides many environmental, economic and social benefits to the community, including reducing stormwater runoff, improving water and air quality, ​moderating summer temperatures, lowering utility costs, improving quality of life and beautifying the city. It is estimated that Ann Arbor’s city-managed urban and community forest, which includes trees growing along streets and in mowed areas of parks, provides nearly $4.6 million in benefits each year. ​​

Adopt-a-​storm drain

​​​Ann Arbor depends on stormdrains and sewers, drainage ditches and culverts to keep streets from flooding during storms. Yet, these devices also collect trash and direct polluted, untreated rainwater straight into our rivers and streams.

Help your community by volunteering with the Huron River Watershed Council's Adopt-A-Stormdrain program​ to help keep our lakes, rivers, and streams free of runoff pollution. ​
