Spring Lake
Meeker County, MinnesotaEutrophic
Spring Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
At a TSI of 59, Spring Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. A maximum depth of 28 ft puts Spring Lake in the middle of Minnesota's depth distribution. The lake's 164 acres and 3.6 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Spring Lake ranks 11 of 23 in Meeker County — solidly in the upper half of the local distribution.
No invasive species are currently listed at Spring Lake — the lake remains off the Minnesota infested-waters roster. The fishery is bass-led, with 12 documented species across the lake's records. A documented public access point at Spring Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.

Top Species by Catch Rate
| Species | Avg CPUE | Avg Weight |
|---|---|---|
| Bluegill | 45.76 | 0.11 lb |
| Yellow Perch | 14.64 | 0.11 lb |
| BLH | 10.16 | 0.43 lb |

| Yellow Bass | 6.34 | 0.68 lb |
CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE = more abundant in standardized sampling.

From the 2018-06-25 survey
A standard survey was conducted at Long Lake near Dassel, beginning on June 25, 2018, to monitor the fish population. Long is a class 34 lake and net catches were compared to similar lakes around the state. The 2014 lake management plan (LMP) listed Bluegill and Largemouth Bass as the primary management species while…
