Grand River Environmental Action Team

The Upper Grand River Watershed is Special in Several Ways

  • At 260 miles, the Grand River is longest river in the State of Michigan and the second largest watershed.
  • The two branches of the Grand River begin at Grand Lake and Center Lake Chain (natural beginnings) in Jackson County and join east of Jackson dropping 467 feet to Grand Haven on Lake Michigan.
  • Headwaters of the Kalamazoo, St. Joseph, and Raisin Rivers are also close. They all flow west to Lake Michigan, except the Raisin which flows east to Lake Erie.
  • Jackson County sits on one of the largest aquifers in North America.
  • There are over 200 miles of river waterways to paddle and hundreds of small lakes.
  • Some of the largest remaining wetlands in lower Michigan are located in this watershed.
  • The potential in this area for river and lake recreation is enormous.
