Does anyone know anything of Alruss Lake? Portage unmarked and fish unknown. Very small lake but I know nothing else and cannot seem to find much on it.

It's a designated trout lake. Rainbow and possibly Brook trout.

didnt believe me, huh?

Status of the Fishery (as of 05/24/2006)
Alruss Lake is in Ecological Lake Class 10, which consists of 76 lakes in northeast Minnesota that are small and have clear and soft (unmineralized) water. Alruss Lake is smaller than most of the lakes in this lake class.

Alruss Lake was thermally stratified on 05/24/2006 with a surface temperature of 62 F and a bottom temperature of 41 F. Adequate oxygen for trout (more than 5 ppm) was retained to a depth of 32 feet, where the temperature was 42 F. Previous investigations showed that in midsummer, 5 ppm oxygen is retained to a depth of about 25 feet, where the temperature was about 60 F. Alruss Lake has no inlets. The outlet to Sandpit Lake has beaver dams and a waterfall that prevent fish movement. Lake bottom substrates along the shoreline are 44% boulder, 26% sand, 19% ledgerock, and 11% rubble. Aquatic plants are sparse and grow to a depth of 6 feet; the most common plants are yellow waterlilies and three-way sedge.

This early summer gillnet assessment for stream trout consisted of two gillnet sets. Two fisheries lake surveys and eight gillnet assessments were previously conducted on Alruss Lake, dating back to 1965. Most of these previous investigations were done in late May or early June and consisted of 1-2 gillnet sets.

The initial fisheries lake survey in 1965 caught no fish, although minnows were observed near the shore. Rainbow trout, splake, or brook trout have been stocked annually since 1966, except for 1968 and 1976. Only brook trout have been stocked since 2000.

Seven brook trout (3.5/gillnet) were caught in 2006. One of these brook trout had been stocked as a fingerling the previous fall and had grown to a length of 6.7 inches when recaptured eight months later. Six brook trout had been stocked as fingerlings in the fall of 2004 and averaged 13.7 inches (range: 12.6 inches to 14.9 inches) when recaptured 20 months later. Five of the trout stomachs contained chironomid midge larvae or adults, while one contained a fathead minnow and one was empty.

The 2006 trout catch of 3.7 lb/gillnet was lower than the median trout catch of 8.5 lb/gillnet in all investigations on this lake, but was similar to the median trout catch of 4.2 lb/gillnet in recent investigations of 25 stream trout lakes in the Tower Fisheries Management Area.

Alruss Lake has had a low population of small white sucker since 1978. The 2006 sucker catch of 2.0/gillnet with an average length of 10.6 inches was similar to previous sucker catches.?

Caught rainbows on it a few years back, not much size to them though .
