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.
Cook Lake, also known as Cork Lake, is a small lake located west of Alexandria adjacent to Lobster Lake. The lake has no public access but winter anglers access the lake off HWY 114. The lake is fringed with dense stands of cattail and water lilies. Submergent vegetation is also extremely abundant. The large amounts of vegetation provide very good spawning and nursery habitat. These plants also enhance water quality by protecting the shoreline from wave action and taking up available nutrients preventing algal blooms. The mid-summer secchi reading was 12.0 feet.Cook lake is utilized primarily in winter due to the lack of a public access. Winter anglers target bluegill and black crappie. Bluegill relative abundance increased from 5.2 fish per trapnet in 1996 to 13.0 fish per trapnet in 2001. Approximately 83% of the sampled fish exceeded 6.0 inches with 10% exceeding 8.0 inches in length. Black crappie numbers have also increased slightly with a trapnet catch of 1.5 fish per net. These fish averaged just over 9.0 inches long.Northern pike can also be active on the lake and catch rates have increased from 6.5 fish per trapnet in 1996 to 9.5 fish per trapnet in 2001. The mean length of the sampled fish was 19.9 inches with the largest fish measuring 22.7 inches. The mean weight these fish was 1.6 pounds.Largemouth bass are extremely abundant with a electrofishing catch rate of 142.5 fish per hour. The size structure, however, is less than desirable with a mean length of 9.6 inches and no fish measuring over 14 inches.
