Beast Lake is an 81 acre, located approximately 29 miles ESE of International Falls. It is located in Voyageurs National Park and the access is limited to a 3/4 mile portage going west off of Mica Bay on Namakan Lake. The sportfish community is comprised of northern pike and smallmouth bass.
Northern pike gill-net abundance in this investigation was 2.33/set which is just below the median of similar lakes, and mean weight was 3.52 lbs. Lengths ranged from 14.0 to 30.4 with a mean of 25.5 inches. Ages ranged from 2-9 with good representation of all year classes present. Growth rates were near the average for lakes in the International Falls management area.
Open water angling was also used to sample smallmouth bass. Nineteen bass were captured in 8 angler hours of fishing for a CPUE of 2.38/hour. Lengths ranged from 5.3 to 17.5 with a mean of 10.7 inches. Eleven year classes were present with ages ranging from 2 to 12 years and good distribution throughout the ages. Growth rates appeared to be slightly slower than average for lakes in the area.
Additional species sampled were one white sucker in a gill net and 122 blacknose shiner's in quarter inch trapnets.
