1996Rates come from standard DNR survey gear (gill nets, trap nets, electrofishing), judged against statewide benchmarks for the same gear, so the same number of fish per net can read differently for two species. Where the standard gear can't count a species reliably, only presence and size are listed. Typical is the middle fish of those measured. Open a row for the full length spread, survey by survey.
How to fish Spectacle Lake through the year
Largemouth bass
- Spring
- Largemouth are moving up into the warming bays and flats, staging around wood, docks and new weeds to spawn. At 15.4 ft of clarity, fish them deeper and lighter than usual.
- Early summer
- Largemouth are on the shallow spawning flats and protected bays, where beds go on firm bottom next to isolated cover.
- Summer
- Largemouth are in and along the weeds: cabbage and milfoil edges, matted cover and shade. On a lake that drops to 51.5 ft, check the deep edge of that structure too.
- Fall
- Largemouth are chasing bait back onto the flats and into the remaining green weeds, feeding hard and shallow before the freeze.
Bluegill
- Spring
- Bluegill are on the beds in firm-bottomed shallows, in colonies of dozens. On a clear lake those colonies sit deeper than you expect. At 15.4 ft of clarity, fish them deeper and lighter than usual.
- Early summer
- Bluegill are off the beds and onto the weed edges and brush, the biggest ones pulling out first.
- Summer
- Bluegill are on the deep weedline of a stratified lake, sliding out as the surface starts back down. On a lake that drops to 51.5 ft, check the deep edge of that structure too.
- Fall
- Bluegill are back up onto the flats and into the last green weeds, feeding hard while the shallows still hold heat.

Longest fish measured by DNR survey crews in each year's nets. Survey gear samples the population, so the lake usually holds larger fish than any survey measured.

From the 2022 survey
A targeted survey of the nearshore fish community in Spectacle Lake was conducted by Fisheries Index of Biological Integrity (IBI) Program Staff on 25 August 2022. Ten sampling sites were evenly spaced around the lake and each was sampled by backpack electrofishing and seining with a 15-foot or 50-foot seine, where possible. Backpack electrofishing was completed at all ten sites. A 50-foot seine was used to sample eight sites, a 15-foot seine was used at one site, and deep, soft sediments with abundant water lilies prevented the use of seines at one sampling site. Nearshore sampling captured 16 native species of fish including five species that are intolerant of disturbance (Banded Killifish, Blackchin Shiner, Blacknose Shiner, Iowa Darter, and Pugnose Shiner) and one species (Green Sunfish) that is tolerant of disturbance.
The nearshore data were combined with gill net and trap net data from an August 2022 survey to describe the fish community and provide a Fish-based IBI (FIBI) score. The FIBI uses fish community data to measure a lake's health, and the types of fish species present can help identify any stressors that may be negatively affecting the lake environment. In Minnesota lakes, certain fish species cannot survive without clean water and a healthy habitat (e.g., Blackchin Shiner, Iowa Darter, and Rock Bass), while other species are tolerant of degraded conditions (e.g., Black Bullhead, Fathead Minnow, and Green Sunfish). The FIBI score, composed of several fish community diversity and composition metrics, indicates the overall health of a lake by comparing it to what is expected for a healthy lake. For additional information on the FIBI, search for "lake index of biological integrity" on the mndnr.gov website.

Results from this survey indicate the fish community of Spectacle Lake is affected by disturbance as indicated by an FIBI score very near to the impairment threshold for aquatic life use determined for similar lakes. Data from this survey will contribute biological information about the health of the fish community to the Rum River Watershed assessment process in coordination with MN Pollution Control Agency.
