Between June 29 and July 24, 1968, counts of boats and fishermen on Clear Lake were made at scheduled times. The peak count was 258 boats between 2 and 3 P.M. on a Sunday, about 1 boat per 14 acres. The total per week came to 5747 boat hours, with about 35% of it on weekends. Boat usage declined earlier in the evening on Sundays than on other days. Power boats constituted about 45% of the total boat hours, and fishing boats about 25%. Water skiers were most active in afternoon and evening, and most of the sailboating occurred on Sundays. Fishing effort per week was estimated at 8121 man-hours, and the weekly catch at 3135 fish, including 1932 bullheads and 491 walleyes.
