(Chapman and Overton 1966). Captured fish were taken to the midpoint of each 

 zone prior to marking and released to prevent introducing a bias into the es- 

 timate. 



CREEL CENSUS 



A partial creel census designed to sample anglers as they left the reser- 

 voir was conducted in 1975 and 1976. A creel census station was established 

 on the main access road to the reservoir (figure 29) and was operated from 

 10:00 A.M. until dark or until all fishermen had left the reservoir. Signs 

 instructing fishermen to stop were erected on the approach to the station. 

 Fishermen were interviewed to determine distance traveled, gender, license 

 type, total hours fished, fishing method, bait, shore or boat, number of fish 

 caught, and number of fish released. Lengths, weights, and scales were taken 

 of the fish which had not been dressed. In 1975 the station was operated on 

 subsequent days during the week (i.e. Monday one week, Tuesday the next week, 

 etc.), and alternate weekend days. The 1976 fishing season was stratified by 

 two week periods, with two weekdays and two weekend days randomly selected for 

 each period. Data were recorded on creel census forms and transferred to com- 

 puter cards for analysis.
