Status of the Fishery (as of 08/18/2008)

Little Jay Gould is a small lake near Cohasset, Minnesota. The lake is relatively clear and appears to support a diverse aquatic plant community. The lake is connected to the Mississippi River via connection to Jay Gould Lake and Blackwater Lake and is part of the larger, Pokegama Reservoir. The US Army Corp of Engineers controls water level at the Pokegama Dam. Little Jay Gould receives water from Pokegama Lake and the Mississippi River depending on water levels. Many homes exist on the lake. The shoreline has been modified and disturbed by residential development in many places.

A population assessment was conducted in August of 2008 to assess the status and characteristics of the fish community. Northern pike were the most common fish captured in gill nets. The catch rate was relatively high but within the expected range when compared to similar lakes. Little Jay Gould has a history of relatively high pike abundance. In 2008, the size structure was relatively poor, as most fish did not exceed 21 inches. Analysis of bony structures identified 7 year-classes. Growth was average and individuals typically exceeded 21 inches in 5 years. Few individuals exceed age-5. Anglers should consider releasing northern pike exceeding 22 inches to increase the number of older, larger fish in the lake. Although abundant, small mean size may limit the popularity of the northern pike fishery.

Black crappies were the second most common fish in the gill net. The gill net catch rate was relatively high when compared to similar lakes. Size structure was favorable as 60% of the individuals exceed 10 inches. Analysis of bony structures identified 6 year-classes suggested fairly consistent recruitment. Growth was average and individuals typically exceeded 8 inches in 5 years. Thirty-four percent of individuals exceeded age-5. Given the age and size structure, good angling opportunities likely exist for this species.

Walleye catch rate was relatively low but within the expected range when compared to similar lakes. Lakes like Little Jay Gould often have low to moderate walleye populations. Size structure was good, however, as most individuals exceeded 15 inches. Five year-classes were present. Growth was average and individuals typically exceeded 15 inches by age-5. Fifty percent of the individuals exceeded age-5. Given the catch rate and size structure, fair angling opportunities should exist. Adjacent Jay Gould and Pokegama lakes are stocked with walleye.

Bluegill were captured in moderate numbers at a rate within the expected range for the lake type. Bluegill catches have been low in previous assessments and the 2008 catch was the highest recorded. The size structure was moderate 48% exceeded 6 inches. Few individuals exceeded 8 inches, however. Several year-classes were present and growth was average with individuals typically exceeding 6 inches in 5 years. Limited numbers and small average size may limit the popularity of the fishery.

Bass are often difficult to assess with test nets, as net avoidance is high. Electrofishing was conducted on Little Jay Gould Lake in June to assess the bass populations. Largemouth bass were sampled in good numbers. The size structure of largemouth bass was good as 22% exceeded 15 inches. Several year-classes were present and growth was average with individuals typically exceeding 15 inches in 5 years. Smallmouth bass were present in limited numbers, as only 3 were captured. The lake has good largemouth bass habitat and largemouth bass are an important component of the fish community. Smallmouth bass were not captured in previous assessments and habitat for this species may be limited.

Other species captured include bowfin, pumpkinseed sunfish, rock bass, shorthead redhorse, white sucker, and yellow bullhead.

The protection of water quality and habitat is critical in maintaining or improving fish and wildlife populations. Unfortunately, human activities often negatively impact our lakes. Fertilized turf-grass lawns and failing septic systems along with the removal of shoreline and aquatic vegetation, mowing to the shore, and installing sand blanket beaches result in destabilized shorelines, uncontrolled erosion, and increased run-off, contributing excess nutrients and sediment to the lake and degrading water quality and habitat. By understanding the cumulative impacts of our actions and taking steps to avoid or minimize them, we can help insure our quality water resources can be enjoyed well into the future. Anglers can further help insure quality fishing by practicing selective harvest and catch and release.
