Birch Lake is a 15 mile long reservoir located northeast of Babbitt. It is accessible by four public ramps and several portages/carry-ins. This 7,074 acre lake has a maximum depth of 25 feet and brown water. Several major inlets flow into Birch Lake and the only outlet is the Kawishiwi River which flows out the far northern tip of the lake. A dam at the outlet is used to control water supplies for the Winton hydroelectric facility downstream at the outlet of Garden Lake; dam operation can result in winter drawdowns of up to 4 feet at times.
On August 17, 2020 Birch Lake was thermally mixed with a surface temperature of 72 F and a bottom temperature of 71 F. Oxygen levels were adequate for gamefish throughout the water column. Lake bottom substrates along the shoreline of Birch Lake are mostly boulder and ledgerock, with gravel, sand and muck in the bays. Aquatic vegetation grows to a depth of 5 feet and is generally limited to the bays.
In the 2020 survey, 192 walleye were sampled for a catch rate of 16.0 fish/gill net, which was very good compared to other similar lakes in the state and the second highest ever on Birch Lake. Walleye lengths ranged from 8 to 29 inches with an average of 12 inches which was slightly below normal compared to past surveys on the lake. Mean weight per fish was just under a pound which was on the low side compared to other similar lakes. Walleye growth was also slower than normal compared to other lakes in the Tower area. Despite large numbers of fish, ages tended to be young with just over 90% of the total catch being five years old or younger.
The northern pike gillnet catch rate of 1.8 fish/net falls just shy of average for Birch Lake and other similar lakes in the state. Lengths ranged from 14 to 35 inches with an average of 23 inches. A special regulation for northern pike (24-36 inch protected slot with one over 36 inches allowed in possession) went into effect in 2003. Pre-regulation August assessments showed that on average, only 29% of northern pike captured were greater than or equal to 24 inches long. Post-regulation assessments continue to show improvement with 49% of pike greater than or equal to 24 inches. Consequently average lengths also improved with a pre-regulation average of 23 inches compared to a post-regulation average of 25 inches.
The cisco (tullibee) catch rate in 2020 was 10.4 fish/net which was above average compared to past investigations on the lake. The average weight was just over a half a pound and sizes ranged from 7 to 16 inches with an average of 10 inches.
Other species sampled in low numbers were yellow perch, white sucker, smallmouth bass, black crappie, and rock bass.
Rusty crayfish are an invasive species that exists in Birch Lake and are in high abundance in lakes downstream of Birch Lake. Counts in Birch Lake have been made of rusty crayfish entangled in gill nets since they first appeared in 2003. Numbers have generally remained low but do show an increasing trend through 2020.Item description -
