Indian Lake is located two and a half miles west of Silver Creek in northwest Wright County. The lake is 146 acres and has a maximum depth of 31 feet. It has a small watershed that is primarily agricultural and this is reflected in the lower water clarity (3.6 foot average in summer). The lake is primarily managed for largemouth bass and sunfish. Curled pondweed grows to nuisance levels in the spring in most of the nearshore areas. Eurasian watemilfoil was discovered on the lake in 2003 during the vegetation survey.Largemouth bass in Indian Lake are abundant. Eighty-one largemouth bass were sampled by electrofishing in May. The catch rate was 72 bass per hour of sampling, above the Montrose average of 56 bass per hour. Most bass caught were between 8 and 12 inches, though some fish greater than 15 inches were sampled.Bluegills are also very abundant in Indian Lake. Historically, the catch rate of bluegill in trap net has remained well above the average for lakes similar to Indian. The average size of bluegills is small (5.8 inches), with only 4% of fish sampled being larger than 7 inches. Both black and white crappie are present in Indian Lake. Historically, black crappies have been sampled in higher numbers but white crappies have been larger in size. In 2003, the catch rates of both black and white crappies were within expected levels for lakes similar to Indian. Most black crappies sampled were between 7 and 9 inches and white crappies were between 9.5 and 11 inches.The northern pike catch in 2003 increased from the 1994 survey, as did the average size of fish sampled (from 2.0 to 4.8 pounds). Northern pike in the lake grow relatively slowly and most of the large fish were over 10 years of age. Large northern pike play a critical role in controlling the population of smaller pike, which can become over-abundant in lakes. Harvesting these large, older fish could shift the fishery back to being dominated by smaller "hammer-handle" sized pike, so it is important to practice catch and release on these larger fish.Walleye were last stocked in Indian Lake in 1992 by the DNR and in 1999 by the lake association. Indian Lake has few yellow perch present and this makes it difficult to establish a walleye population. Gill net catches of walleye in Indian Lake have remained low, even when more frequent stocking occurred. The gill net catch in 2003 was low, but average size of fish was large (2.8 pounds). Most fish sampled came from the 1999 stocking, though one fish was from the 1992 year class (24.8 inches).Other fish sampled in the survey included white sucker, black bullhead, hybrid sunfish, pumpkinseed sunfish and golden shiner.

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.
