Sullivan Lake is a small (73 acre), highly developed lake located between Buffalo and Maple Lake in Wright County. The lake has a maximum depth of 58 feet with moderate water quality with an average summer water clarity of seven (7) feet. There is one (1) public access located on the east side of the lake. A lake survey was completed July 6 - 9, 2020 to update fisheries data last collected in 2001 and included summer gill netting and trap netting.

A floating leaf and emergent vegetation survey was completed in September. Cattail (50 acres) and waterlilies (17 acres) were the most abundant species and covered 48% and 66% of the shoreline, respectively.

Spring electrofishing is the preferred sampling method to assess Largemouth Bass populations; however Largemouth Bass sampling was not conducted in 2020 due to the COVID-19 pandemic. Largemouth Bass were last surveyed by electrofishing in 2001 with only 10 small fish sampled ranging in length from five (5) to seven (7) inches.

The Black Crappie catch for gill net sampling in 2020 was lower than 2001, but within the range of expected values for similar lakes. The trap net catch in 2020 was similar to 2001 and the long term average for the lake. Twenty-two Black Crappie were sampled and ranged in length from six (6) to 10 inches with an average length of seven (7) inches.

Bluegill were abundant and small during the 1970s and 1980s, but abundance has declined to more normal levels recently. The catch in 2020 was significantly higher than 2001, but still within the range of expected values for lakes similar to Sullivan. Bluegill sampled ranged in length from three (3) to eight (8) inches with an average length of six (6) inches. Forty percent of the Bluegill sampled were longer than six (6) inches and none were longer than eight (8) inches.

Northern Pike are abundant and offer anglers the opportunity to catch good numbers as well as quality-sized pike. However, anglers are encouraged to harvest small pike (<22 inches) and release the medium-sized pike (>26 inches) to help balance the size structure. Northern Pike numbers in 2020 were high, but similar to 2001 and above the range of expected values for similar lakes. Northern Pike ranged in length from 18 to 32 inches with an average length and weight of 23 inches and three (3) pounds. Twenty-one percent of the Northern Pike sampled were longer than 26 inches and 4% were longer than 30 inches.

Walleye are not a managed species in the lake and have never been stocked in the lake by the state. No Walleye were sampled in 2020 and only three (3) Walleye (all caught in 2001) have ever been sampled in the lake.

Yellow Perch abundance was extremely low. Over the course of four (4) surveys (1983 - 2020) only 10 Yellow Perch have ever been sampled. Low numbers of Yellow Perch is likely due to the high Northern Pike abundance.

Other species sampled included: Black, Brown, and Yellow Bullhead, Bowfin (Dogfish), Golden Shiner, Green Sunfish, Hybrid Sunfish, and Pumpkinseed.
