Watersheds in your District

These maps explore the overlap of human and natural boundaries to help elected officials make wise and informed decisions about the waterways that flow through their Michigan legislative districts.

What is a watershed?

A watershed is an area of land wherein all of the rain and melting snow drains to a single body of water such as a creek, river, or lake. Nearly all of Michigan’s watersheds eventually flow into one of the Great Lakes.

Why are watersheds important?

  • Healthy watersheds reduce flood risk, support crops, filter pollutants, mitigate effects of climate change, and boost human wellbeing.
  • Our actions upstream have consequences downstream.
  • Water is only as clean as the land it flows over.
  • A river or lake is only as healthy as the water draining into it.
