Fish Status

BLUEGILL

Very Good

Bluegill were collected from Arrowhead Lake during the 2017 survey at a rate that was higher than that of the previous seven years. Fifty-three percent of bluegill were larger than 6 inches (exceeding the management plan goal), but the proportion larger than 7 inches decreased from 29 to 9%. Bluegill body condition was below the management plan goal range.

CHANNEL CATFISH

Very Good

Channel catfish were collected at a rate during the 2017 Arrowhead Lake electrofishing survey that was a slight increase compared to the previous year. Channel catfish ranged in size from 13 to 22 inches and were in fair condition. Channel catfish are stocked every other year to sustain the population. Site Regulation: 6 fish daily limit

CRAPPIE

Poor

Very small numbers of black and white crappie were included in the 2017 Arrowhead Lake sample. White crappie ranged 6 to 12 inches, while black crappie were 7 to 10 inches in length. Crappie body condition remained substandard. Site Regulation: 15 fish daily limit.

LARGEMOUTH BASS

Good

Largemouth bass were collected at a rate in spring 2017 that was higher than the previous two years, and much higher than the management plan goal. Percentage of 12-inch and larger bass was higher than the previous 15 years at 54%, and this index achieved the management plan goal for the first time in 10 years. Most bass ranged from 9 to 14 inches in length, but a few were larger than the upper end of the lake’s slot limit of 15 inches and one weighed 7.8 pounds. The proportion over 15 inches was 7%, and bass body condition remained slightly substandard. Site Regulation: 12 to 15-inch protective slot; 2 bass per day under 12 inches and 1 per day over 15 inches.

REDEAR SUNFISH

Good

Redear were less abundant than bluegill, as usual, in 2017. Eighty-eight percent of redear were larger than 7 inches in length, and 75% were larger than 8 inches, while 38% were over the 9-inch mark. Redear body condition remained very good.

YELLOW BASS

Very Good

Yellow bass (7-10 inches) were collected at a rate of 320 per hour of electrofishing, and these fish have the potential to impact growth and survival of all other sport species. For this reason, anglers should be encouraged to remove yellow bass from Arrowhead Lake whenever possible.
