Embarrass Lake is located approximately one mile east of Biwabik. It has a surface area of 507 acres and a maximum depth of 19 feet. There are two concrete ramps for public access at the municipal campground.
The Embarrass River flows through a chain of lakes before it reaches the Saint Louis River. Embarrass Lake is between Wynne and Cedar Island Lakes in this chain. There is a stop log dam about 200 yards upstream of the lake that is a periodic barrier to upstream fish movement. Lake bottom substrates along the shoreline of Embarrass are mostly rubble and sand. Aquatic plants grow to a depth of 5 ft and are generally sparse.
The most abundant gamefish in the lake were walleye and northern pike. Panfish were also present in low numbers. The fishery is diverse and includes bluegill, channel catfish, shorthead redhorse and three species of bullhead.
Walleye numbers in 2012 (4.6/gill net) were slightly higher than the long term average for all assessments on this lake. Embarrass lake is stocked with fingerlings every other year. Most walleye were from the 2010 year class but there were also many walleye from the 2009 year class indicating there is some natural reproduction. The average walleye sampled was 12.0 inches long and 3 or 4 years old. The largest walleye sampled was 16 inches long.
Northern pike numbers in 2012 (2.7/gill net) were lower than the long term average for all assessments on this lake. The pike were small on average at 16.9 inches long and about 3 years old. The largest pike sampled was 27.0 inches.
Yellow perch were low in abundance but showed a wide range of sizes from 6 to 12 inches long. Bluegill (1.4/trap net) and black crappie (0.6/trap net) were sampled in low numbers. The largest bluegill sampled was 10.0 inches and the largest crappie was 12.6 inches. Other species sampled include rock bass, and channel catfish. Yellow, black, and brown bullhead were all sampled. Most of these other species were relatively low in abundance with the exception of white sucker.
Rusty crayfish were found in low abundance throughout the lake for the first time in a fisheries assessment. Rusty crayfish are an invasive species and are illegal to introduce to lakes or other waterbodies.
