Field note · Minnesota stocks by year, not by truck day: walleye fry go in within weeks of ice-out, fingerlings and yearlings mostly in fall, and stream trout in spring and fall. A row here means the fish went in during that year; DNR adds the year's rows after the fact, so the current year can look empty until winter.

Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.
Sagamore Lake is a former open pit iron ore mine pit located in the Cuyuna Country State Recreation Area. Rainbow Trout are stocked annual as yearlings (2,000/year) into Sagamore. Temperature and oxygen conditions suitable for trout occurred from a depth of about 15' down to around 60' in July 2023. Rainbow Trout provide for a popular fishery, especially early in the season. Rainbow Trout were sampled at 2.0/gill net, with an average length of 13.0". Lake Trout were first stocked in 2019, with 635 yearlings being stocked biennially. One 11.7" Lake Trout was sampled in this survey. The management goal is to have a self-sustaining Lake Trout population by 2031. Sagamore has a special regulation for Lake Trout: All less than 20" must be released with a possession limit of one. Northern Pike were sampled in low numbers at 1.1/gill net. Average length was 24.5", with 50% in the protected 22-26" slot. Northern Pike measuring at least 26" in length made up 25% of the catch. Tullibee (Cisco) were first stocked into Sagamore in 2019 as adults. They were introduced to provide forage for the Lake Trout population. The gill net catch of 0.3/net was below average for similar lakes. All Tullibee (Cisco) sampled were adults from past stocking efforts, with an average length of 15.8". No invasive species have been discovered in Sagamore, but they are in the area. Lake users are required to inspect and remove any aquatic plants and animals from their watercraft and trailers, as well as pull the plug and drain all water from the watercraft, including bilges, livewells and baitwells.
