Rates 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 Big Watab 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 16 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 123 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.
Northern pike
- Spring
- Pike are in the shallow bays and along new weed growth. At 16 ft of clarity, fish them deeper and lighter than usual.
- Early summer
- Pike are on the outside weed edge and points.
- Summer
- Pike are on the deep weed edge and points near the coolest water they can find. On a lake that drops to 123 ft, check the deep edge of that structure too.
- Fall
- Pike are on the last green weeds and the breaks beside them, feeding heavily as the water drops.

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.

MN DNR · in their words
From the 2025 survey
A targeted survey of nearshore fish species in Big Watab Lake was conducted on June 23 - 25, 2025, by Lake Biological Monitoring and Assessment Program (LBMA) staff. Sampling sites were evenly spaced around the lake, and each was sampled by backpack electrofishing and seining with a 50-foot or 15-foot seine, where possible. Backpack electrofishing was completed at 10 sampling stations. Similarly, a 50-foot seine was used to sample six stations, and a 15-foot seine was used at four stations. Nearshore sampling captured 14 species of fish including seven species that are intolerant of disturbance (i.e., Banded Killifish, Blackchin Shiner, Blacknose Shiner, Iowa Darter, Least Darter, Pugnose Shiner, and Rock Bass) and one that is tolerant of disturbance (i.e., Green Sunfish).
A concurrent summer trap net survey was also conducted by LBMA staff. Nine trap nets were set along the shoreline in locations that encompassed multiple habitat types. Trap net sampling captured seven species of fish including one that is intolerant of disturbance (i.e., Rock Bass). Bluegill comprised a majority of the catch by number and biomass.
Read the full DNR narrative
The nearshore and trap net were combined with gill net data from a July 2023 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., Green Sunfish and Common Carp). 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 web site.
Results from this survey provide evidence that the fish community in Big Watab Lake is healthy as indicated by an FIBI score that exceeds the exceptional use threshold determined for similar lakes. These results are similar to the FIBI from 2023. The survey results will be considered when the biological health of the lake is assessed during the Mississippi River Sartell watershed assessment process, which will be completed in coordination with MN Pollution Control Agency. You can help protect the fish community in Big Watab Lake by reducing runoff, maintaining natural shorelines, and preventing the spread of invasive species.
