HISTORY AND STATUS OF FISHERY

Dinham is a 207 acre lake located 2 miles south of Melrude, MN on County Road 59. There is a DNR administered public access in the northeast bay off of Township Road 542. Maximum depth is 25 feet, with 64% of the lake less than 15 feet deep. Dinham was last assessed in 2002. Dinham was surveyed during the summer of 2010 to update information about fish populations.

Walleye abundance of 0.2 per gillnet lift was down from 2002 (0.7) and was below average compared to other Minnesota lakes of similar type. The walleye gillnet has historically been low on Dinham and has ranged from 0.0 in 1972 to 1.0 in 1957 and 1978. Walleye average length was extraordinary at over 27 inches but only two individuals were captured. Not enough individuals were sampled to evaluate stock density or growth. Two year-classes were represented, 1999 and 2001. Both year-classes correlate to years that walleye fry were stocked before the discontinuation of stocking in 2001.

Northern pike abundance of 1.3 per gillnet lift was down from 2002 and average compared to other Minnesota lakes of similar type. Average length was 24.8 inches, but not enough individuals were sampled to evaluate stock density or growth. All year-classes from 2005 to 2008 were represented.

Black crappie abundance of 1.3 per trapnet lift was up from 2002 (2.1) and was below average when compared to other Minnesota lakes of similar type. Black crappie mean length was 7.1 inches and growth was average compared to other Duluth Area lakes. All year-classes from 2002 to 2007 were represented.

Bluegill abundance of 10.2 per trapnet lift was up from 2002 (6.4) and was average when compared to other Minnesota lakes of similar type. Average length of sampled bluegills was 5.2 inches and growth was slow compared to other Duluth Area lakes. All year-classes from 2003 to 2007 were represented.

A total of 53 largemouth bass were sampled with electrofishing equipment. The catch rate of largemouth bass was 72.7 fish per hour of electrofishing. The 2002 largemouth bass electrofishing catch rate was 16.6 fish per hour. Largemouth bass average length was 12.4 inches and growth was average compared to other Duluth Area lakes. All year-classes from 2001 through 2007 were represented.

Yellow perch abundance of 0.7 per gillnet lift was down from 2002 (1.0) and was below average compared to other Minnesota lakes of similar type. Average length of perch was 5.4 inches, but not enough individuals were sampled to evaluate stock density or growth. Perch from the 2006 and 2008 year-classes were present.

Other fish species sampled included brown and yellow bullhead, golden shiner, pumpkinseed and white sucker.

Information was collected on aquatic vegetation, substrate and water quality. Thirty-five aquatic plant species or species groups were identified along 20 transects. Large-leaf pondweed and flat-stem pondweed were the most frequently found plant species (90% of transects) followed by variable-leaf pondweed (85% of transects). The most common substrate types were sand and gravel which were identified along 70% and 50% of the transects, respectively. Results of laboratory water analysis indicate Dinham is an alkaline, moderately hard water lake with moderate fertility.

Dinham was included in an index of biotic integrity (IBI) assessment in 2010. In addition to standard gillnets and trapnets, beach seines and backpack electrofishing equipment were used to index species richness of the nearshore lake habitat.
