Status of the Fishery (as of 06/20/2011)

Hogback Lake is 40 acres with 60% littoral area, having a maximum depth of 43 feet. Located 12.2 miles east of Isabella, MN on USFS Road #172 (Dumbbell Lake Road), there are three drive-in campsites, one remote campsite (water access), an outhouse, a back-in gravel ramp access to the lake and a barrier-free fishing pier. Anglers can also fish from shore on Hogback Lake at various places along the hiking trail, on the north and east sides of the lake. Designated Stream Trout Lake signs are posted near each access point on the north side of the lake.

Hogback Lake is one of the more popular managed stream trout lakes in the Finland Management Area and gets high fishing pressure in the summer and winter angling seasons. Splake fingerlings are stocked annually in the fall and rainbow trout yearlings are stocked annually in the spring.

The splake numbers sampled in Hogback Lake were average for the Finland Area and similar to catches in previous investigations. The average length of the catch was 8.9 inches (0.4 pound); the largest splake sampled was 22.7 inches (4 pounds). Sixty-seven percent of the splake sampled in 2011 were yearlings, stocked as fingerlings in the fall of 2010, which brought down the average size of the fish in this report.

The rainbow trout numbers sampled in 2011 were above average for the Finland Management Area. The average length of rainbow trout in the catch was 11 inches (0.7 pound), the largest rainbow trout 20.3 inches (3.7 pounds). More than 50% of the rainbow trout sampled were yearlings stocked in the spring of 2011, which brought down the average size of the fish in this report. Rainbow trout populations are difficult to assess with any sampling gear, many different methods have been tried to attain a larger sample without much success. Angling for rainbow trout is often better for the public in Hogback Lake than population assessment catch rates would indicate.

One yellow perch was collected in the 2011 lake survey, the first time yellow perch were sampled in Hogback Lake since the 2002 lake rehabilitation project. Yellow perch are a problem in managed stream trout lakes, out-competing the stocked fish for food and negatively affecting trout survival and growth
