Triangle Lake is located 13 miles east of Ely. There are two "remote" public accesses. The most commonly used access is a 50 yard roller portage between the southern shore of Ojibway Lake and the northern shore of Triangle Lake. The portage is slightly uphill to Triangle but boats up to 16 feet long are able to be rolled over a series of rollers which are attached to two rails. The other access is on the southern shore and is a 160 rod portage to the North Kawishiwi River. This 300 acre lake contains no major inlets and only one outlet which is about 90 feet long and drops 4 feet in elevation to Ojibway Lake. Triangle Lake has a maximum depth of 45 feet and the water color was green at the time of the survey with a slight algae bloom. On July 20, 2020 Triangle was thermally stratified with a surface temperature of 73F and a bottom temperature of 44 F. Oxygen levels were adequate for gamefish to a depth of 19 feet where the water temperature was 59 F. Lake bottom substrates along the shoreline of Triangle Lake are mostly boulder, rubble, gravel, and ledgerock. Aquatic plants are sparse and grow to a depth of 6 feet. The overall gillnet catch rate for all fish combined was 21.2 fish/net which was slightly better than average compared to past catches. Total yield was 32.9 lbs/net which was below average for the lake. Fish species sampled in gill nets were walleye, northern pike, yellow perch, white sucker, rock bass, smallmouth bass, and cisco. The overall trapnet catch rate for all fish combined was 8.3 fish/net which was slightly better than average compared to past catches. Total yield was 8.7 lbs/net which was also better than average. Eighty-nine walleye were sampled in gill nets for a catch rate of 9.9 fish/net, which was very good compared to past surveys on Triangle and other similar lakes. Sizes ranged from 8 to 28 inches with an average of 14 inches, which was slightly smaller than past surveys. Growth rates were good with the average fish reaching 15 inches at four years old. Ages ranged from 1 to 18 with the strongest year classes coming from 2017 and 2018, the latter being a stocked year. Triangle is stocked with walleye fry every three years. The northern pike gillnet catch rate was 3.3 fish/net which was good compared to similar lakes and better than average for Triangle Lake. Lengths ranged from 19 to just over 38 inches with an average of 23 inches, which was similar to past surveys. Nine smallmouth bass were sampled in gill nets for a catch rate of 1.0 fish/net which was above average compared to other similar lakes and right at Triangle's historic average. The average weight was over two pounds which was very good compared to other similar lakes. Lengths ranged from 8 to 19 inches with an average of nearly 15 inches. Although the sample size was small, the fish aged did show exceptional growth rates with the fish reaching 12 inches by age four. Ages ranged from 3 to 11 years. Twenty-six yellow perch were sampled in gill nets for a catch rate of 2.9 fish/net which was above average compared to other similar lakes and past surveys on Triangle. Sizes were small with a range from 6 to 8 inches. Rusty crayfish, which are an invasive species, were first observed in Triangle Lake in the 1986 survey. Subsequent counts of rusty crayfish caught in gill nets have bounced around but generally remained high over time. The 2020 survey sampled them at 66.3 crayfish/net which was the highest catch rate since 2003.
