History & Status of the Fishery
Jacob Lake, better known locally as Louis Lake, is located within the Boundary Waters Canoe Area Wilderness (BWCAW) within the Superior National Forest and is a non-motorized lake. It is accessible by a 250 yard portage off the wide spot of the Horse River, just north of Mudro Lake. It has a maximum depth of 52 feet and very clear water. The lake was thermally stratified on June 4, 2014 with a surface temperature of 69 F and a bottom temperature of 39 F. Ample oxygen for trout was retained to a depth of 30 feet; the temperature was 40 F at this depth. Prior to 2002, brook trout, rainbow trout, and splake were stocked in Louis Lake. Since 2003 brook trout is the only species that was stocked. From 2003 to 2010 the St. Croix Falls strain of brook trout were used for stocking. Since 2011, Minnesota Wild strain brook trout were used. Growth and survival rates are currently being evaluated for this new strain. The catch of brook trout by weight in this assessment was 5.5 lbs/gill net which is just above the established goal. This catch rate was also slightly higher than average for all stream trout lakes within the Tower Fisheries Management Area. Note that trout abundance is expressed in terms of biomass (lb/net) rather than number/net to reduce the influence of occasional high catches of just-stocked fingerlings. Nine brook trout were captured and ranged in size from 10 to 18 inches with an average of 13 inches. Size structure seems to be somewhat small however, with only three of the nine fish being over 15 inches; the remaining six were all less than 12 inches. Stomach content analyses of eight fish showed 3 were empty, 2 contained invertebrates, 2 contained leeches, and 1 had crayfish remains.
