Water on your land: wetlands, drains, ponds, and the beach
Home and property
This page explains Michigan law in plain English so you know what questions to ask. It isn’t legal advice, and water rules turn on exactly where your land sits. Before you dig, fill, or fight, talk to EGLE’s district office, your county drain commissioner, or a Michigan attorney.
The short version
Water is where landowners get blindsided, because the rules are invisible until you touch them. The soggy back corner may be a state-regulated wetland. The ditch along the road may be a legal “county drain” you can be billed for. And the Great Lakes beach below the high-water mark belongs, in a walking sense, to everyone.
Wetlands: permits before shovels
You need an EGLE permit before filling, dredging, draining, or building in a regulated wetland. That applies on private land, regardless of zoning — and not knowing it was a wetland is no defense. What’s regulated, generally: wetlands connected to or near lakes and streams, plus larger isolated ones (five acres and up). The state’s wetland inventory maps are clues, not answers. EGLE’s fee-based Wetland Identification Program gives a definitive on-site call — cheap insurance before you buy or build.
Farming exemptions exist — established agricultural activities, grazing, farm and stock ponds, drain maintenance. They’re real but narrow. Expanding into new wetland is where farmers get in trouble. A few local governments also regulate smaller wetlands, so both permits can apply. Penalties for unpermitted fill include restoration orders. Bulldozing first is the most expensive shortcut in rural Michigan.
The county drain commissioner (the most Michigan office there is)
Under the Drain Code of 1956, your county’s elected drain commissioner maintains hundreds of established “county drains.” Many of them look like ordinary creeks and ditches. Work on a drain is financed by special assessments on every parcel in the drainage district — which is why you can get a bill for a ditch you’ve never seen. Projects start by petition, often from a handful of landowners or a municipality. There are public hearings, and the appeal windows are measured in days, not months. If a drain notice shows up in your mail, act on the letter, not the eventual bill. One useful interaction: PA 116-enrolled farmland is exempt from many special assessments. Another reason that program matters.
Ponds
Small upland farm and stock ponds are generally exempt from wetland permitting. Dig in a wetland or near a stream and you’re in permit territory. Bigger projects can trigger dam-safety and soil-erosion rules too. The honest advice: one call to EGLE’s district office before the excavator shows up.
Docks, seawalls, and inland shorelines
Inland lakes and streams (Part 301 of the environmental code) and Great Lakes bottomlands (Part 325) have their own permit systems. They cover dredging, seawalls, major dock projects, and beach grooming. Know the names, and call EGLE before structural work at the water line.
Riparian basics, and the beach-walking rule
Waterfront (“riparian”) owners on inland lakes generally own the bottomlands to the middle of the lake. They share reasonable use of the surface with other riparians and the lawfully launched public. Public road ends at lakes are a classic fight: they’re generally access points, not private beaches or dock farms.
On the Great Lakes, the rule is settled. Glass v. Goeckel (Michigan Supreme Court, 2005) held that the public trust covers the shore below the ordinary high-water mark. Walking the Great Lakes beach along the water is lawful, even in front of private cottages. Lounging, bonfires, and cutting across private land to reach the beach are not. One sentence of law; a century of arguments settled. (Beach safety and beach treasure cover the fun side of that strip.)
Who decides
EGLE: wetlands, streams, and shorelines. Your county drain commissioner: drains and their assessments — find yours through your county’s page. The courts: riparian disputes.
The signpost
EGLE’s Water Resources Division pages cover wetlands and shoreline permits, including the Wetland Identification Program. Your drain commissioner’s office explains any drain letter. MSU Extension covers the farm exemptions well. Start at Owning Land in Michigan.
