History & Status of the Fishery
Sonju Lake is a 37 acre lake with a maximum depth of 8 feet located 5 miles northeast of Finland Minnesota. There is a carry in access down a fairly steep hill from the Sonju Lake road to the northwest corner of the lake. Other than the access there is no development on the lake shore, it is entirely in public ownership. Sonju Lake connects to the East Branch of the Baptism River, a designated trout stream by way of an unnamed creek.
The purpose of the spring 2016 targeted survey was to assess if any Brook Trout remained in the lake following the decision to discontinue stocking in 2014. No Brook Trout were sampled during the 2016 survey. It is possible that Brook Trout may move into the lake seasonally from the East Branch of the Baptism River, but is unlikely that they can maintain a population in the lake year round due to the limited depth. The only fish sampled during the 2016 survey were White Sucker and Common Shiner.
With the notable exception of summer 2009 (an exceptionally cold summer) the trout fishery in Sonju Lake and net catch in Sonju Lake have been poor. Surveys of winter dissolved oxygen have revealed that it is inadequate to support Brook Trout through the winter; due to the shallow depth of the lake (max depth 8 feet) summer temperatures are not suitable for Brook Trout either. Most likely as a result of these two issues, observed survival of stocked Brook Trout was very poor. Brook Trout stocking on Sonju Lake was discontinued in 2014. From a game fish perspective, this lake will not be of interest to most anglers as there are no permanent gamefish populations. It however is a scenic lake and may be of interest to canoers and duck hunters, it has been used in the past as a source of bait for local minnow dealers.
