Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.
Regenbogen Lake is located 9 miles north of Ely. There is one access which is a carry-in (0.3 mile portage) off the Echo Trail, which does cross private land. Regenbogen Lake is a ten acre lake with a maximum depth of 34 feet. A mix of rainbow trout and brook trout were stocked in Regenbogen from 1956 to 1983. From 1983 to 2010 only brook trout were stocked. Brook trout stocking was discontinued after 2010 due to a reduction in the stream trout program. Recently, there has been a renewed push in the program with some previously stocked stream trout lakes potentially being added back to the stocking list. This survey was done with the anticipation that Regenbogen Lake may at some point be stocked again. Only one large brook trout was sampled in two gillnet sets in 2015. The 18 inch fish weighed 3.2 pounds and is the biggest brook trout sampled from Regenbogen Lake. Twenty-one white suckers were sampled for a catch rate of 10.5 fish/net. This is the highest catch rate on record for sucker on the lake. Sizes were small with an average of 8 inches and the largest being 12.5 inches.
