Status of the Fishery (as of 07/09/2007)

Walleye abundance appeared to have been down in 2007, although the average size of the fish that were collected was high. All walleye taken in 2007 had been produced naturally, but there had been no strong year classes recently. Walleye growth rates had been good, thanks largely to the presence of an excellent yellow perch forage base.

Northern pike were fairly abundant in 2007, and some larger fish were present. Most of the fish taken were two years of age, with none older than five years of age. Northern pike growth had also been good.

Walleye and northern pike fisheries were supplemented by smallmouth bass, yellow perch, and panfish fishing opportunities in 2007. Smallmouth bass were present in typical numbers for this lake. As has usually been the case in Northern Light Lake, most of the smallmouth bass collected were large. Yellow perch abundance was lower than has been seen in the past in this lake, but it was still high for a lake of this type. The lake supported a high-quality perch population, with many fish larger than eight inches. Pumpkinseed sunfish were also fairly abundant, and while most were small, fish as large as 7.6 inches were seen.

Travel down the Brule River to Northern Light Lake was very difficult in 2007, due to low water and heavy vegetation. Only canoes were able to get through with any ease, and use of an outboard in the channel was nearly impossible by the end of the summer. Higher water from heavy rains in fall 2007 may ease that situation for 2008.
