Status of the Fishery (as of 06/07/2005)

Okamanpeedan (Big Tuttle) is a 2,294 acre lake of which only 1,313 acres are in Minnesota. The remaining 981 acres reside in Iowa. The lake has a maximum depth of 6.5 feet, has 12.2 miles of shoreline and is located near the town of Ceylon in Martin County. The lake is presently managed for northern pike primarily while yellow perch and white crappie are managed secondarily. Since the lake is connected to the Des Moines River and fish have a way of re-establishing themselves, the lake is only stocked with northern pike in the event of a "catastrophic" winterkill.

Northern pike catch rates were lower in 2005 than what we saw in 1998 and 1993. Despite the lower catch rates, Okamanpeedan is still a popular northern pike lake for local anglers. Only two northern pike were sampled in our trap nets which were 18.7 and 23.7 inches in length.

Walleye catch rates were similar to what we saw in 1998. Two walleye, which were 17.5 and 20.8 inches in length, were sampled in trap nets. Several boats were observed during the assessment at the outlet throughout the survey. According to angler interviews, "nice" walleye were being caught near the outlet above the dam.

Yellow perch catch rates were what we would expect for lakes similar to Okamanpeedan. Yellow perch lengths ranged from 4.4 to 9.8 inches and averaged 6.8 inches. Three different ages of yellow perch were observed during the survey.

White crappie catch rates were also what we would expect for lakes similar to Okamanpeedan. White crappie lengths ranged from 6.9 to 12.2 inches and averaged 8.7 inches. Two ages of white crappie were observed during the survey of which a majority of the fish were two years old. The white crappie population was in very good condition.

Black crappie catch rates were lower than what we would expect in lakes similar to Okamanpeedan. Black crappie lengths ranged from 6.9 to 8.2 inches and averaged 7.1 inches. Two ages of black crappie were observed during the survey.

Black bullhead catch rates were higher than what we would expect in lakes similar to Okamanpeedan. Black bullhead lengths ranged from 6.3 to 8.2 inches and averaged 7.6 inches.

Carp catch rates were also higher than what we would expect for lakes similar to Okamanpeedan. Carp lengths ranged from 5.1 to 31.9 inches and averaged 19.8 inches.

Bigmouth buffalo catch rates were what we would expect for lakes similar to Okamanpeedan. Bigmouth buffalo lengths ranged fro 14.9 to 27.1 inches and averaged 19.7 inches.

The only other species of fish caught in our nets in 2005 was orangespotted sunfish.

To promote and maintain healthy fish populations, pollution and other inputs need to be controlled. Fish habitats are directly affected by water quality. Nutrient, sediment and other waste inputs can drastically alter the biological, chemical, and physical components of a lake. It is paramount to maintain if not improve the current water quality of Okamanpeedan Lake through watershed management to preserve this fishery for future generations to enjoy.
