Status of the Fishery (as of 07/14/2008)

A resurvey was conducted on Diamond Lake during July of 2008. Diamond is a moderately large (1,565 acres), productive, and moderately deep (27 feet maximum) lake located in Kandiyohi County. There are numerous small inlets and one large inlet that drain primarily agricultural row crops via tile systems into Diamond. The outlet connects to the Middle Fork of the Crow River via a ditch system. The immediate watershed is primarily agriculture with residential, hardwoods, and wetlands composing the remainder. Diamond Lake is highly developed with 352 homes/cabins, one resort, and one county park/campground. The southeast bay "Dogfish" bay is the least developed portion of the lake. Submergent vegetation species are varied and densities moderate in Diamond. Curly-leaf pondweed has been a nuisance especially along the north portions of the lake in the past, but has been less bothersome in recent years. Pondweeds (narrow-leaf, sago, clasping leaf, etc.) were moderately abundant in 2008. The most common submergent species present during 2008 were muskgrass, narrow-leaf pondweed, water moss, northern milfoil, and clasping-leaf pondweed. Emergent vegetation present included mostly hardstem bulrush (north point, east shoreline area) and cattail species (Dogfish Bay). Shoalwater substrates of the main basin were mostly sand, rubble, and gravel. Silt and muck compose the majority of substrates in Dogfish Bay. Mid summer dissolved oxygen levels (>7.0 ppm) were good down to 25 feet deep during 2008. Total phosphorus levels were moderate (0.033 ppm) in June of 2008. Chlorophyll-a levels were low (2.30 ppb) in June of 2008. Water clarity was moderate to good during the 2008 summer (6.0 - 14.5 feet). Walleye natural reproduction is frequent and significant in Diamond compared to other Spicer Area lakes. Diamond is managed primarily for walleye, with northern pike, black crappie, bluegill, yellow perch, and largemouth bass managed as secondary species.

Black crappie numbers were abundant in 2008 (15.00 fish/gillnet) compared to the normal ranges for Diamond (25th=0.08, 50th=2.83, 75th=7.65 fish/gillnet) and similar lakes. The 2008 black crappie abundance in trapnets (10.67 fish/trapnet) was also above the normal ranges for Diamond (25th=1.29, 50th=3.08, 75th=5.88 fish/trapnet) and similar lakes. The black crappie historical catch rates are 4.99 fish/gillnet and 3.92 fish/trapnet. The black crappie average sizes were similar for both gillnets and trapnets (0.44 pounds and about 9.14 inches) in mid-July of 2008. The historical average weights were 0.23 and 0.38 pounds for gillnets and trapnets respectively. The 2008 catch rate of quality size (8.00 inches) and larger black crappie was high (14.25 fish/gillnet). Black crappie growth rates were above the Spicer Area normal ranges for ages 1-3. The 2005 year class comprised 96% of the 2008 black crappie gillnet and trapnet catch. There were low numbers of young of year "YOY" black crappie (2.67 fish/haul, 1.93 inches average length) captured in the 2008 shoreline seine hauls.

Local anglers had excellent success catching black crappie (8-10 inches average size) throughout the 2007-08 winter. Conservation Officers reported that limits of black crappie were common occurrence for anglers during this time period. There were 184 fish houses counted on Diamond during mid January of 2008 by DNR personnel. One local angler reported over 800 ice-fishing shelters on the ice during one weekend in late January of 2008 during the peak fishing success. In the 2008-09 winter, anglers reported moderate success for catching black crappie (10-12 inches average size).

Bluegill numbers were moderate in 2008 (5.25 fish/trapnet) compared to the normal range for Diamond (25th=2.99, 50th=4.50, 75th=6.87 fish/trapnet), but low compared to the normal range for similar lakes. The bluegill historical average catch rate is 10.61 fish/trapnet. The 2008 bluegill average size was large to moderate (0.28 pounds and 6.30 inches) from trapnets. The bluegill historical average weight is 0.23 pounds from trapnets. Local anglers reported catching low numbers, but large sized bluegill during the 2007-08 winter. The 2008 catch rate of quality size (6.00 inches) and larger bluegill was moderate (3.42 fish/trapnet). Bluegill growth rates were above the Spicer Area normal ranges for ages 1-4. The 2005 year class comprised 64% of the 2008 gillnet and trapnet catch. There were abundant numbers of YOY bluegill (114.17 fish/haul, 1.47 inches average length) captured in the 2008 shoreline seine hauls.

A spring electrofishing survey for largemouth bass was not conducted due to time constraints in 2008. Largemouth bass abundance was high in the 2003 spring electrofishing survey (27.00 fish/hour, 1.84 pounds average weight) compared to the Diamond historical average (17.24 fish/hour, 1.92 pounds average weight). There were moderate numbers of YOY largemouth bass (22.67 fish/haul, 2.20 inches average length) captured in the 2008 shoreline seine hauls.

Northern pike numbers were moderate in 2008 (3.75 fish/gillnet) compared to the normal ranges for Diamond (25th=1.67, 50th=3.75, 75th=4.92 fish/gillnet) and similar lakes. The northern pike historical average catch rate is 4.20 fish/gillnet. The 2008 northern pike average size was moderate to large (4.73 pounds and 26.80 inches) for Diamond. The northern pike historical average weight is 2.71 pounds from gillnets. The catch rate of preferred size (28.00 inches) and larger northern pike was moderate (1.50 fish/gillnet) in 2008. Northern pike growth rates were above or within the Spicer Area normal ranges for ages 1-7. The 2005 year class comprised 32% of the 2008 gillnet and trapnet catch.

Yellow perch numbers were moderate to abundant in 2008 (54.25 fish/gillnet) compared to the normal ranges for Diamond (25th=19.43, 50th=31.00, 75th=60.13 fish/gillnet) and similar lakes. The yellow perch historical average catch rate is 43.07 fish/gillnet. The 2008 yellow perch average size was moderate (0.19 pounds and 7.31 inches) from gillnets. The yellow perch historical average weight is 0.14 pounds from gillnets. The 2008 catch rate of quality size (8.00 inches) and larger yellow perch was 10.80 fish/gillnet. Yellow perch growth rates were near or above the Spicer Area normal ranges for ages 1-3. The 2006 and 2005 year classes comprised 50% and 45% respectively of the 2008 gillnet and trapnet catch. There were abundant numbers of YOY yellow perch (115.33 fish/haul, 2.52 inches average length) captured in the 2008 shoreline seine hauls.

Walleye numbers were low to moderate in 2008 (8.75 fish/gillnet) compared to the normal ranges for Diamond (25th=8.00, 50th=14.00, 75th=19.79 fish/gillnet), but high compared to the normal ranges for similar lakes. The walleye historical average catch rate is 16.64 fish/gillnet for Diamond. The 2008 walleye average size was moderate (1.47 pounds and 14.63 inches) from gillnets. The walleye historical average weight is 1.71 pounds from gillnets. The 2008 catch rate of quality size (15.00 inches) and larger walleye was low (2.25 fish/gillnet). Walleye growth rates were below the Spicer Area normal ranges for ages 1-3, but within or above the normal ranges for ages 4-8. The two prominent walleye year classes present in the 2008 gillnet and trapnet catch were from 2006 (31%) and 2005 (40%). Abundant numbers of YOY walleye due to natural reproduction were noted in fall electrofishing surveys of 2005 and 2006.

The YOY walleye catch rate was low (22.00 YOY/hour) in the 2008 fall electrofishing survey compared to the Spicer Area historical average (76.32 YOY/hour). The 2007 YOY walleye numbers were also low (22.00 YOY/hour). The Diamond Lake historical average YOY walleye catch rate is 138.03 YOY/hour. The 2008 walleye YOY average size (6.57 inches) was slightly larger than the Spicer Area (6.34 inches) and Diamond (6.46 inches) historical average sizes respectively. The 2006 YOY walleye catch rate was the second highest (528.00 YOY/hour, 5.43 inches) for Diamond. The highest recorded Diamond catch rate was 604.00 YOY/hour in 1996. There were abundant numbers (190.00 fish/hour, 10.15 inches average length) of yearling walleye (2006 year class) captured in the 2007 fall electrofishing survey. We also observed abundant numbers (140.00 fish/hour) of adult fish (probably from the 2006 year class) in the 2008 fall electrofishing survey. Recent walleye stockings included 1998 (37,274 fingerlings, 2,261 pounds) and 2004 (19,354 fingerlings, 925 pounds; 276 yearlings, 46 pounds; 487 adults, 348 pounds).

Black bullhead numbers were low in 2008 (1.25 fish/gillnet) compared to the normal ranges for Diamond (25th=1.35, 50th=9.50, 75th=24.38 fish/gillnet) and similar lakes. The black bullhead historical average catch rate is 35.22 fish/gillnet. Black bullhead abundance was also low in the 2008 trapnets (0.50 fish/trapnet). Black bullhead abundance was high (221.00 fish/gillnet) during the previous 2003 assessment. The 2008 black bullhead average weights were large (1.11 and 1.87 pounds from gillnets and trapnet respectively). The black bullhead historical average weight is 0.80 pounds for both gillnets and trapnets.

Common carp numbers were moderate to high in 2008 (1.25 fish/trapnet) compared to the normal ranges for Diamond (25th=0.47, 50th=0.91, 75th=1.44 fish/trapnet) and similar lakes. The carp historical average catch rate is 1.50 fish/trapnet. The 2008 carp average size was large (10.26 pounds and 26.99 inches) from trapnets. The carp historical average weight is 6.73 pounds from trapnets.

Current fish management activities on Diamond include monitoring the fish population on a periodic basis, protecting aquatic vegetation through the permit process, participating in local watershed initiatives, and stocking various fish species as warranted. A fall electrofishing survey is scheduled to assess walleye natural reproduction in 2009. A fish population assessment is scheduled for 2013.
