A population assessment was conducted at Arvilla Lake in 2009 to evaluate the lake's fish population. A total of 16 different species of fish were sampled, plus hybrid sunfish. Arvilla has a history of partial winterkills, with the latest documented kill occurring during the 2007-2008 winter. The lake was not stratified on 6/29/09 and dissolved oxygen was 7 mg/l from top to bottom. Clarity was poor, due to an algae bloom, with a secchi disk reading of 1.5 feet.

Gill nets sampled 36 northern pike for a catch rate of 6.0/net, which was within the normal range for this type of lake. The 2004 catch rate was almost identicle at 6.4/net. Northern pike were 10.2 to 30.7 inches long averaging 20.5 inches. Trap nets sampled fish up to 35.1 inches in length. Northern pike were 1 to 5 years old with 5 year-classes present. Growth was moderate.

Gill nets sampled 36 walleye for a catch rate of 6.0/net, which was within the normal range for this type of lake and the highest ever measured at Arvilla. The 2004 catch rate was 1.8/net. Walleye were 9.5 to 26.2 inches long averaging 14.7 inches. Trap nets sampled walleye up to 27.6 inches in length. Walleye were 2 to 12 years old with 6 year-classes present. Approximately 78% of the gill net catch was from the strong 2007 year-class. Growth was fast. The old stocking regime (500 fry/littoral acre two-out-of-three years), which started in 1998 and ended in 2005, produced a unsatisfactory catch rate in 2004. A new regime (1,000 fry/littoral acre every-other-year) was initiated in 2007 and this first evaluation indicated favorable results.

Spring night-time electrofishing sampled 13 largemouth bass for a catch rate of 13.5/hr. This was the first time that electrofishing was used on Arvilla to sample largemouth bass. Largemouth bass were 4.6 to 13.5 inches long averaging 8.9 inches. Largemouth bass were 1 to 5 years old with 4 year-classes present. Growth was moderate. Dead largemouth bass were found on shore following the 2007-2008 winter.

Gill nets sampled 5 channel catfish for a catch rate of 0.8/net. The catch rate in 2004 was 2.4/net. Gill netted fish were 20.2 to 23.5 inches long averaging 21.4 inches. Several dead channel catfish were found on the shoreline following the 2007-2008 winter. Channel catfish could be partially responsible for the apparent drop in black bullhead numbers at Arvilla.

Trap nets sampled 118 black crappie for a catch rate of 13.1/net, which was within the normal range for this type of lake. The 2004 catch rate was 10.4/net. The 2009 gill net catch was 23.5/net, which was well above the normal range and the highest ever observed at Arvilla. The 2004 gill net catch was 7.6/net. Gill netted black crappie were 3.8 to 10.8 inches long averaging 7.1 inches. Trap nets sampled fish up 13.98 inches in length. Black crappie were 1 to 8 years old with 8 year-classes present. Growth was moderate.

Trap nets sampled 56 white crappie for a catch rate of 6.2/net which was above the normal range for this type of lake. Only 1 white crappie was sampled during the 2004 population assessment. Gill nets sampled 48 white crappie in 2009, for a catch rate of 8.0/net which was within the normal range and the highest ever recorded at Arvilla. Gill netted white crappie averaged 5.2 inches in length. Trap netted white crappie were 4.5 to 13.9 inches long averaging 8.1 inches.

Trap nets sampled 108 bluegill for a catch rate of 12.0/net, which was within the normal ranged for this type of lake. The 2004 catch rate was 19.9/net. Bluegill were 2.8 to 7.95 inches long averaging 5.8 inches. Approximately 17% of the trap net catch was 7 inches or longer. Bluegill were 1 to 7 years old with 7 year-classes present. Growth was moderate. Dead bluegill were found on shore following the 2007-2008 winter.
