Biggest Inland Lake in Michigan: Houghton Lake (20,044 acres)

Houghton Lake is Michigan's largest inland lake per the Michigan DNR, Institute for Fisheries Research. Below: 50 Michigan lakes ranked by surface area.

The largest inland lake in Michigan is Houghton Lake at 20,044 acres , in Roscommon County, according to the Michigan DNR, Institute for Fisheries Research. Lake Michigan is larger at 22,300 sq mi water area (US EPA). Michigan borders four Great Lakes (Superior 31,700 sq mi, Huron 23,000, Michigan 22,300, Erie 9,910), all vastly larger. Houghton is the largest lake entirely inside Michigan.

Houghton Lake isn't in our water-quality index — we grade lakes with enough EPA Water Quality Portal samples to score, which leaves out many large reservoirs and border waters. The ranking below covers the 50 Michigan lakes with nutrient and algae readings, led by Houghton Lake.

Reading Michigan's size profile

Michigan's largest lake by surface area is Houghton Lake in Roscommon County, spanning 20,070 acres and reaching 21 ft deep. Most of Michigan's biggest waters are natural basins left by glaciers, with stable shorelines and deep main basins.

Surface area is a poor proxy for water quality on its own — a large lake can hold a clean, deep core and a nutrient-loaded bay at the same time. Each lake below links to its full page with nutrient readings, clarity, depth, and EPA impairment status. Area figures come from state DNR surveys and the USACE National Inventory of Dams; water-quality readings come from EPA and state monitoring data.

Frequently Asked Questions

What is the largest lake in Michigan?

Houghton Lake, at 20,044 acres, in Roscommon County. Lake Michigan is larger at 22,300 sq mi water area (US EPA). Michigan borders four Great Lakes (Superior 31,700 sq mi, Huron 23,000, Michigan 22,300, Erie 9,910), all vastly larger. Houghton is the largest lake entirely inside Michigan. Source: Michigan DNR, Institute for Fisheries Research, 1962 (DNR lake inventory map: marginal survey 1935-36, depth contours revised Oct. 1962; retrieved 2026-07-30).

How is lake surface area measured?

Surface area comes from state DNR lake surveys and, for reservoirs, US Army Corps of Engineers (USACE) National Inventory of Dams records. Area is reported in acres at normal pool level. Reservoirs rise and fall with management and drought, so their listed area is the long-term normal rather than a single-day reading.

Are Michigan's largest lakes natural or reservoirs?

Of the top 50 Michigan lakes by area, 3 sit on a dammed river (reservoirs) and 47 are natural basins. Glacial states (MN, WI, MI, NY) skew natural; plains and southern states (MO, IA, ND, OH) skew toward reservoirs built for water supply, flood control, and recreation.

Do larger lakes have better water quality?

Not reliably. Quality varies more within a big lake than between lakes — a large lake can have a clean, deep main basin and a murky, algae-prone bay fed by a tributary, so one reading can mask wide swings. Depth, watershed land use, and how fast the lake flushes matter far more than raw surface area.

How big is the typical Michigan lake in this ranking?

Across the top 50 Michigan lakes by surface area, the median is 4,136 acres (South Manistique Lake). This list is biased toward the biggest waters; the typical Michigan lake is far smaller.
