East and West Twin Lakes are managed as one lake: Twin Lake. Twin Lake is located east of the north arm of Burntside Lake off the Echo Trail in northern St. Louis County. Access to the lake is via the Dead River from Burntside Lake or a 70 yard portage from Everett Lake. The Minnesota Department of Natural Resources has classified Minnesota's lakes into 43 different types based on physical and chemical characteristics. Twin Lake is in lake class 10. Lakes in this lake class are small in size (mean: 100 acres), have high amounts of area that are 15 feet or less (mean percent: 52), and with clear water.
Anglers who make the long trip into Twin Lake can expect to catch a variety of species including northern pike, walleye, black crappie, bluegill, and yellow perch. Northern pike have an abundance that is typical of other lake class 10 lakes. Pike ranged in length from 18.4 inches to 35.1 inches with a mean length and weight of 24.4 inches and 3.4 pounds.
There is a low density population of walleye in Twin Lake. Numbers can be considerably higher in the early spring however because of spawning walleye from Burntside Lake. Mean length and weight of walleye in Twin Lake was 16.6 inches and 1.7 pounds. The largest walleye captured in 2011 was 29 inches. Walleye is stocked in even-numbered years. Walleye aged over the past seven assessments showed that 56 of 63 were from stocked years.
The most abundant species that anglers can expect to catch is bluegill. Their abundance is on the high range of what you would expect to find in this lake class. Bluegill are generally small with few fish greater than seven inches. Black crappie are also available for anglers however, none were captured over 9.3 inches.
Other fish sampled include yellow perch, pumpkinseed, rock bass, and white sucker.
Twin Lake was selected for fish index of biotic integrity (IBI) sampling. This index is designed to help determine the overall health of the biological fish community of the lake. This type of sampling will typically capture the non-game species and young-of-year game species. For Twin Lake, ten species were sampled. Golden shiner and tadpole madtom were non-game species sampled. Black crappie, largemouth bass, smallmouth bass, and yellow perch young-of-the-year were also sampled.
Twin Lake was designated as infested with spiny waterflea in 2010 due to its connection to Burntside Lake. As of the 2011 survey, no spiny waterflea were observed.

Recreational activities such as recreational boating, angling, waterfowl hunting, and diving may spread aquatic invasive species. Some aquatic invasive species can attach to boats, while others can become tangled on propellers, anchor lines, or boat trailers. Many species can survive in bilge water, ballast tanks, and motors or may hide in dirt or sand that clings to nets, buckets, anchors, and waders. Fortunately, completing simple steps can prevent the transport of aquatic invasive species.
