Pumpkinseed and bluegill are present in very low numbers, black bullhead in average numbers and northern pike in high numbers. Northern pike present, are, for the most part, naturally reproduced fish. Bluegill numbers have been drastically reduced from levels found in earlier surveys (1970, 1975). One possible reason is undetected winterkill conditions. Largemouth bass and bluegill young of the year were found in shoreline seining.

Two adult Brown Trout (BNT) averaging 21.32\" TL and 4.08 pounds were captured during this survey. These fish were surplus brood stock that had been culled from the state hatchery system and stocked the previous Fall to provide a put-and-take fishery. Northern Pike (NOP) were sampled below the median levels for abundance and above the median level for mean weight in 2007. The average size NOP captured was approximately 22.6 inches and 2.8 pounds. Bluegill (BLG) were sampled in the highest abundance of any species during this survey. The trap net catch rate for BLG was the highest ever recorded for this lake, but no individuals larger than 5.7 inches in length were captured. The average size for sampled BLG is 4.5 inches and 0.05 pounds (19.5 fish/lb). Growth rates for NOP and BLG were found to be below average.

Bluegills were sampled in the highest abundance of any species during this survey. The trap net catch rate for Bluegill was the highest ever recorded for this lake, but the average size is small with only 23 individuals out of total of 397 (6%) larger than 6.0 inches in length being captured. Growth rates for Northern Pike and Bluegill were found to be below average when compared to statewide averages. Other panfish seen during this survey were Pumpkinseed and Hybrid Sunfish, each of which was also sampled in their highest abundance ever. These other panfish were found to be small in size and have poor to slow growth for lakes similar to Holland Lake. Six Largemouth Bass were observed in the sampling gear, these fish had an average length of 12.36 inches and an average weight of 1.42 lbs. Some other fish seen in during this survey were Black Crappie which were observed in low numbers and were of small size and Green Sunfish which were also not very numerous and small in size.

The lake is currently managed by the Fishing in the Neighborhood (FiN) program. Holland is located entirely within Lebanon Hills County Park in the City of Eagan. There is a fishing pier at the park, and recreational boating is restricted to kayaks and canoes. The fish community primarily includes Northern Pike, Bluegill and Largemouth Bass. Yearling Rainbow Trout are stocked every fall, providing a put-and-take winter trout fishery. Additionally, adult Brown and Rainbow Trout are stocked when available.
\n
\nNorthern Pike were sampled at a rate of 5.0 fish per gill net in 2024, falling between the first quartile and median catch rates for the lake class, and slightly below the 2013 rate of 8.5 fish per gill net. Historical catch rates for Northern Pike have ranged from 0.50 to 8.50 fish per gill net since 1975, with an average of 4.9 fish per gill net over the past five surveys (since 1995). The proportion of larger pike has increased since 2013. Northern Pike lengths ranged from 15.55 to 30.39 inches, with a mean of 23.82 inches and a mean weight of 3.19 pounds.
\n
\nBluegills were sampled at a rate of 4.5 fish per trap net, slightly above the first quartile for the lake class but the second-lowest catch rate recorded for Bluegill in this lake. Historical catch rates range from 10.50 to 49.75 fish per trap net, except a rate of 0.25 fish per trap net in 1980. The 2024 catch rate falls below 24.06 fish per trap net, which is the average catch rate across the last five surveys (since 1995). In 2024, Bluegill lengths ranged from 3.35 to 5.2 inches, with a mean of 4.28 inches.
\n
\nWhile not a preferred sampling method, gill nets captured Largemouth Bass at a rate of 1.00 fish per gill net, the median for this lake class. The two bass captured were both 15.55 inches in length, with a mean weight of 2.04 pounds. Historical surveys indicate low catch rates for Largemouth Bass, with 0.50 fish per gill net recorded in 2013 and 1995, and no bass sampled in 2007 and 2001.
\n
\nPumpkinseed Sunfish and Hybrid Sunfish have historically been present in low abundance in trap net surveys. In 2013, both species reached their highest recorded catch rates, at 10.88 and 6.75 fish per trap net, respectively. In 2024, catch rates declined to 1.75 Pumpkinseed Sunfish and 0.88 Hybrid Sunfish per trap net. Pumpkinseed Sunfish had a mean length of 4.72 inches, while Hybrid Sunfish averaged 5.2 inches.
\n
\nAlthough Rainbow Trout are stocked annually (and Brown Trout periodically) in Holland Lake, none were captured in the nets in 2024. Additionally, one 16.54-inch White Sucker was sampled.
\n
Fish numbers in the 1995 survey were low. Fish aged were small and growth was slow. Bluegill, pumpkinseed, green, and hybrid sunfish were captured, with most under 6 inches in length. Black and white crappie were captured for the first time in the lake, with no fish over 9 inches. Three largemouth were sampled, one of acceptable size to anglers. One black bullhead was captured, down from previous nettings.

average abundance - a significant reduction from previous investigations. This may be a result of lower water levels as a result of recent drought conditions. Growth of pike was average for the area. Golden shiners were abundant. Bluegill were sampled in average numbers, but were of small average size. Bluegill abundance has remained stable for several investigations. Hybrid sunfish were sampled at higher than state and local median levels. Black bullheads were sampled at above local median levels and were small in size. Higher numbers of small largemouth bass were sampled in gillnets. Three largemouth bass year classes were sampled which exhibited average growth for the region.
"},{"narrative":"The fish population of Holland Lake has primarily consisted of northern pike, bluegill, and largemouth bass. Northern pike were sampled above median levels for abundance in gill nets and at the highest catch rate ever observed. The average northern pike sampled was 22.24 inches in length and 2.95 pounds. Thirty-one percent of the gill net sample of northern pike was 26.0 inches or larger. Overall growth rates were near average for this species. Bluegill and pumpkinseed sunfish were sampled above median levels for abundance in trap nets and at the highest catch rates ever observed. The average size of sampled bluegill was 4.9 inches in length and 0.08 pounds. Only 8.1% of all bluegill captured were 6.0 inches or longer. Pumpkinseed sunfish averaged only 4.22 inches in length. Two small largemouth bass yearlings and no adults were sampled during this assessment. Recent management efforts for this lake have attempted to develop a two-story fish population by stocking brown and rainbow trout. Adult brown trout broodstock culls have been stocked here since 1998. Yearling rainbow and brown trout have also been stocked since 2000. No trout were captured during the 2001 netting assessment.
