Stocking Notes
1 - indicates fish purchased and stocked by private citizens and sporting groups.
2 - indicates fish purchased by the DNR for stocking.

Stocking Fish Sizes
Fry - Newly hatched fish that are ready to be stocked usually called "swim-ups". Walleye fry are 1/3 of an inch or around 8 mm.
Fingerling - Fingerlings are one to six months old and can range from a size of one to twelve inches depending on the species. Walleye fingerlings range from three to eight inches each fall.
Yearling - Yearling fish are at least one year old. A one-year-old fish can range from three to twenty inches depending on the species. Walleye yearlings average from six to twelve inches.
Adult - Adult fish are fish that have reached maturity. Depending on the species, maturity can be reached at two years of age. Walleye reach maturity between the ages of four and six years.

Fish Consumption Guidelines

These fish consumption guidelines help people make choices about which fish to eat and how often. Following the guidelin es enables people to reduce their exposure to contaminants while still enjoying the many benefits from fish.

Status of the Fishery (as of 08/22/2011)

Hall Lake is a 513 acre lake of which 277 acres are within the littoral zone of 15 feet or less. The lake has been dredged and has a maximum depth of 27.0 feet. Hall Lake is part of the "Fairmont Chain of Lakes" and is within the city limits of Fairmont. The Fairmont Chain of Lakes (from headwaters to mouth) is comprised of Amber Lake, Hall Lake, Budd Lake, Sisseton Lake, and George Lake which are all natural impoundments of Center Creek in the Blue Earth River Watershed. Hall Lake is the largest and deepest of the lakes with a watershed-to-lake ratio of 43 indicating a large influence of the watershed effects in the lake. The city of Fairmont operates a storm water runoff system that empties into the lakes and the city also draws drinking water from Budd Lake, so it is imperative to reduce negative influences of water impairments in the watershed to improve the water quality in the lakes. Martin County Soil and Water Conservation District has taken the lead on this and has implemented some projects that help reduce the effects of water quality impairments on the lake, but more can be done to virtually eliminate all influences through best management practices in the watershed. Fish community changes over time tell us a lot about the health of an aquatic environment and its water quality. Hall Lake is a class 43 lake and is managed primarily for walleye while crappie, yellow perch and channel catfish are managed secondarily. Fish population assessments have been conducted every 4 to 6 years since 1984 with an initial assessment conducted in 1953. A recent fish population assessment was conducted during the week of August 22, 2011 to analyze the current management of species in Hall Lake and to determine changes in the fish community over time.

In 2011, the walleye catch rates were 2.7 fish per gill net and 0.8 fish per trap net. The catch rates were within the normal range for gill nets (1.2 to 6.3 fish per net) and trap nets (0.3 to 1.2) but below the long-term average of 7.1 and the management goal of maintaining a gill net catch rate of 5.0 fish per net. While the catch rate did not meet the management goal, there is some sign of improvement since the 2005 survey. The gill net catch rate in 2005 was 1.0 fish per net indicating an increase in abundance of walleye in Hall Lake in 2011. Surplus walleye fingerling stocking (not part of the ordinary stocking plan) took place in the fall of 2011 (all Fairmont lakes included) which should continue to boost the population in Hall Lake. While the abundance was less than desired, the sizes of walleye in the population was good. The average length of fish in the gill nets was 14.9 inches and 12.4 inches in the trap nets with a range of 8.9 to 28.4 inches. Growth was average as walleye reached 13.9 inches by age 3. The average condition of the fish was fair. Usually, when condition is fair in August it indicates a population that is experiencing some kind of stress. In August the walleye should be feeding well and be past the reproductive stresses of spring indicating the stress is forage related. Competition for food with other species can be a huge factor in walleye success and there are many species to compete with in Hall Lake, most notable would be crappie and channel catfish (both on the rise in terms of abundance). Increasing the abundance of a top predator such as northern pike (through a protected slot limit) may lead to decreased abundance of other species and lead to improvement in the overall walleye population as a result.

Yellow perch may be a good targeted species in Hall Lake. The 2011 gill net catch rate of yellow perch in Hall Lake was the second greatest in the history of population assessment sampling with a catch rate of 45.0 fish per gill net and greater than the long-term catch rate of 27.7 fish per net. The yellow perch catch rates indicate a population that is meeting management expectations. The size structure of the yellow perch was excellent; the average length of yellow perch caught in the gill nets and trap nets was 8.6 and 8.5 inches, respectively, with a range in length from 5.6 to 10.7 inches. The overall condition of the yellow perch in the sample was average, in August, which means the fish were exhibiting a less than desired overall condition in the peak of their prime growing season. The cause of the average condition factor may be explained by the high abundance of yellow perch in the sample causing a general decline in weight per individual due to competition for food resources. Overall, the yellow perch population is exceeding management goals for Hall Lake and will continue to maintain similar abundance for several years as the 8.5 inch average size fish continue to grow for 3 or 4 more years.

Bluegill are another managed species in Hall Lake. The management goal is to maintain the bluegill population within the normal trap net range of 7.5 to 62.5 fish per net for Hall Lake. The 2011 trap net catch rate was 4.9 fish per net which is below the normal range, falling short of the management goal, but near the long-term average catch rate of 6.1 fish per net. The size structure of the bluegill population favored larger fish; the average size of bluegill in the trap net sample was 7.5 inches with a range of 5.9 to 9.0 inches. The overall condition of the bluegill was good for an August sample. Overall, it appears the size structure and condition of bluegill in Hall Lake is good while the population level is at a less than preferred level. Even at low abundance the bluegill are doing well; given a successful spring spawn their abundance may increase.

In 2011, the channel catfish gill net catch rate was at the greatest level observed since sampling began in 1984 with a catch of 15.7 fish per gill net. The long-term average in Hall Lake is 5.0 fish per gill net, so the 2011 catch is over 3 times the long-term average. The catch rate of channel catfish in the trap nets was 4.2 fish per net, trap nets are not a target gear for channel catfish. The size structure of channel catfish in Hall Lake is very good; the average size of channel catfish caught in the gill nets was 18.2 inches with a range of 8.1 to 26.8 inches, fish up to 28.4 inches were caught in trap nets. The average condition of channel catfish was average, which is usual for an August sample and indicates a population that is finding adequate forage. Channel catfish would be an excellent targeted species in Hall Lake during those hot summer nights.
