Iowa State Record Brook Trout: 7 lb
The Iowa state record brook trout weighed 7 lb. It was caught in 1996 from Fountain Springs by Doug Korvarik, and the Iowa DNR still recognizes it as the state mark 30 years later.
Where the record came from
The record came from Fountain Springs. We don't carry a water-quality grade for it: our index covers standing lakes with enough EPA Water Quality Portal samples to score, which leaves out rivers and tributaries, Great Lakes water, and smaller ponds that are rarely sampled. Browse the Iowa lakes we do grade instead.
Brook Trout records by state
Iowa ranks 3 of 6 among the states in our index for record brook trout. Wisconsin holds the heaviest at 9 lb 15 oz, set in 1944.
| # | State | Weight | Year | Water |
|---|---|---|---|---|
| 1 | Wisconsin | 9 lb 15 oz | 1944 | Prairie River |
| 2 | Michigan | 9 lb 8 oz | 1996 | Clear Lake |
| 3 | Iowa (this page) | 7 lb | 1996 | Fountain Springs |
| 4 | Pennsylvania | 7 lb | 1996 | Fishing Creek |
| 5 | Minnesota | 6 lb 5.6 oz | 2004 | Lake Superior tributary |
| 6 | New York | 6 lb 3 oz | 2025 | St. Regis Canoe Area |
Each figure comes from that state's own fisheries agency. Agencies differ on what they certify — some recognize catch-and-release length records alongside weight — so treat this as a comparison of standing certified weights, not a single national list.
How it ranks inside Iowa
12 of Iowa's 19 standing records are heavier than the 7 lb brook trout — unsurprising, since record weight tracks species size more than anything about the water. 10 Iowa records have stood longer, the brook trout mark dating to 1996.
