Purvis Lake, also known as Sparrow Lake, is in Ecological Lake Class 10. Lake Class 10 consists of 76 lakes in northeast Minnesota that are small with very soft (low mineral content) water. Purvis Lake was thermally stratified on 08/03/2009 with a surface temperature of 65 ?F and a bottom temperature of 41 ?F. Adequate oxygen for fish (2 ppm) was retained to a depth of 26 feet where the temperature was 45 ?F.

Lake bottom substrates along the shoreline are mostly boulder, with some gravel, sand, and muck. There are no inlets. The outlet leads to the Beaver River and was obstructed by a large beaver dam, blocking most of the flow and acting as a barrier to fish movement at the time of the 2009 survey. Water levels were high in 2009, which caused flooding of terrestrial grasses and sedges along the shoreline.

The 2009 survey consisted of four gillnet sets to assess the fish population in Purvis Lake. Five previous fish population investigations, dating back to 1966, consisted of 2-8 gillnet sets. No trapnets have been set in Purvis Lake due to the difficult portage access.

The 2009 total catch of fish (all species combined) in gillnets of 6.5 fish/net (9.82 lbs) was nearly identical to the median catch of 6.4 fish/net (7.1 lbs) for all investigations on Purvis Lake. Northern pike were the most abundant fish sampled in 2009, followed by walleye. Low numbers of largemouth bass, white sucker, yellow perch, and rock bass were also caught. Pumpkinseed sunfish were captured in the 1999 assessment but were not caught in any other investigation. Lake Class 10 is one of the least productive lake classes in northeast Minnesota in terms of gillnet catches of fish.

The northern pike catch rate in 2009 (3.3 fish/gillnet) was normal for Lake Class 10 and higher than the median catch (2.4 fish/gillnet) for all investigations on this lake. Average northern pike size in 2009 was 18.1 inches (1.3 lbs), which was smaller than the average length (20.5 inches) for all assessments on Purvis Lake and smaller than normal for this lake class. The largest pike captured in 2009 was 24.4 inches long. Four age classes were present in the 2009 assessment with most (10 of 13) coming from the 2007 year class. Northern pike growth was normal by area standards.

The walleye catch rate in 2009 (1.8 fish/gillnet) was normal for Lake Class 10 and slightly higher than the median catch (1.4 fish/gillnet) for all investigations on Purvis Lake since walleye fry stocking began in 1975. Similar to previous assessments, walleye sizes were large averaging 18.6 inches (2.2 lbs) and the largest captured in 2009 was 22.7 inches. Six of 7 walleye caught in 2009 were from fry stocked year classes (2004 and 2006). The seventh walleye was from the non-stocked 2003 year class. Growth of walleye caught in 2009 was faster than normal by area standards.

Largemouth bass numbers in 2009 (0.5 fish/gillnet) were normal for this lake class and identical to the median catch for all investigations on Purvis Lake. Angling reports in previous years, along with the fact that largemouth bass are not sampled effectively in gillnets, suggests largemouth bass numbers in Purvis Lake are likely higher than the gillnet catch indicates.
