A winter creel census of bluegills (Lepomis macrochirus) conducted on Pool 7 (Lake Onalaska, Wisconsin) on the Upper Mississippi River in 1976‐1977 used a half‐day sampling schedule and car counts to estimate angler numbers. The calculated harvest was based on these counts plus data from interviews with 3,429 anglers. The total estimated harvest for the 17‐week fishery (22 November‐18 March) was 233,061 bluegills taken by 25,402 anglers during 96,519 hours of fishing (2.41 fish per hour). Of the bluegills harvested, 52% were taken during the first 5 weeks of the fishing season. Average length and weight of bluegills harvested was 178 mm and 136 g, respectively; total estimated weight of the catch was 31,696 kg.
