East Chub Lake is easily accessible off of Highway 1, just northeast of Isabella, MN, and has a gravel back-down access that can accommodate boat trailers. The lake is 62 acres and has a maximum depth of 9 feet. Sand and gravel shoreline around the lake provide room for shore-fishing, especially during low water levels. With the exception of a small piece of privately owned land containing cabins, the shoreline is mostly public land.
East Chub's game fish community is composed of northern pike and yellow perch, as well as small (less than 4 inches) pumpkinseed. Also present are white suckers and some minnow species. The lake has a soft bottom, clear water (a Secchi disc is visible to the bottom), and a moderate amount of aquatic vegetation. Several boulders surround the East Chub's small island, located on the western side of the lake; some boulders are near enough to the water surface to present a hazard for boat motors. East Chub Lake is connected to West Chub Lake by a small channel that cuts through the bog on the northwestern shoreline; the lake has no outlets.
Northern pike sampled in 2012 averaged 21.3 inches and 2.0 pounds; the largest pike sampled was 26.9 inches (3.5 pounds). Catch rates of northern pike were above average for similar lakes in the area, northern pike 20-24 inches are fairly abundant in East Chub Lake. Compared to the 2006 assessment, the northern pike population has improved and now has more fish that are slightly larger on average.
Yellow perch sampled were smaller than average in 2012, measuring 6.7 inches and 0.14 pounds, on average. The largest yellow perch sampled was 9.1 inches (0.3 pounds); about 18% of the yellow perch sampled were over 8 inches. Catch rates of yellow perch were higher than average compared to similar lakes in the area. Yellow perch appear to have strong year classes every 3-5 years in East Chub, and high abundances of these strong year classes may result in slow growth (and smaller size) of perch.
East Chub's only sunfish species, pumpkinseed, are very small and average 3.5 inches. The largest pumpkinseed captured during the 2012 survey was only 3.7 inches; the pumpkinseed in East Chub Lake may provide forage for northern pike, but are most likely too small to attract angling pressure.
Historically, the East Chub Lake fish community also included walleye, bluegill, and largemouth bass, and rock bass. However, a partial winterkill in 2003/2004 removed these species from the fish community. Periodic winterkill conditions still occasionally affect the lake, limiting the potential for reintroductions of these species. Northern pike are now the top game fish in the lake and the high abundance of medium-sized pike provides good angling opportunities.
