Page 5 LAKE SURVEY REPORT INITIAL SURVEY DATED 08/02/1995 FOR DOW NUMBER 27-0045-00 Discussion The present fish population consists of black bullhead, bluegill, green sunfish, and fathead minnows. This population structure is typical of a winterkill. Black bullheads were captured in numbers over 5 times the third quartile level for lake class 37. The mean weight of fish sampled was equal to the first quartile. The black bullhead mean length was 6.0 inches. Only four bluegills were sampled in the seven trapnet sets, even though 400 were stocked in 1994 by the city of Edina. This is well below the first quartile level for number per set. The mean length of the bluegills was 4.3 inches. The largest individual fish was 4.9 inches in length. Green sunfish were sampled in numbers over 6 times the third quartile range (interquartile range 0.2 to 12.4). The mean weight of fish sampled was equal to the first quartile level of 0.2. The mean length was 6.3 inches. Largemouth bass were stocked at the same time as the bluegills by the city of Edina. None of the 600 fish stocked were captured by the trapnets or during seining. Page 6 LAKE SURVEY REPORT INITIAL SURVEY DATED 08/02/1995 FOR DOW NUMBER 27-0045-00 Status Of The Fishery Arrowhead Lake is a small, shallow winterkill lake. The 1995 lake survey found black bullheads and green sunfish dominating the population. Each species was sampled in numbers well above average for similar lakes. The average size of fish, for both species, was slightly below average. Only 4 bluegills were sampled during the survey, even though 400 were stocked by the city of Edina in 1994. None of the 600 Largemouth bass stocked by the city were sampled.
