Rush Lake is about 6 miles north of Ottertail. Types of fish in the lake include panfish, crappie, bluegills, sunfish, pike, perch, walleye and bass. Iron in the lake keeps visibility low, so fish aren't scared off easily. Depth of the lake varies quite a bit, so you either have to know the part of the lake you are fishing, ask someone or have a depth finder on hand. A Minnesota fishing license is required, and limits are enforced.
Ottertail Lake is at the edge of the town of Ottertail. The lake is about 14,000 acres and has a large population of walleye. There is no minimum size limit on walleye, but each fisherman can keep only one fish over 20 inches. Other fish found here include perch, pike, bass and lake sturgeon. Fishing depth is gradual from the edge to the middle and is not as up and down as Rush Lake. Maximum depth is 120 feet. The lake is regularly stocked to keep levels up.
Rose Lake is about 25 miles northwest of Ottertail. It is a small lake of about 1,100 acres but has a good depth of 137 feet. Access to the lake can be found on the northwest side. Walleye are stocked regularly, however, other fish are also found within the waters, including sunfish, bass, bluegill, bullhead and pike. No out-of-state bait is allowed in the fishing waters of Minnesota in order to prevent invasive species from entering the state's waters.
