Notes
Survey followed a roving-roving design. All funding was provided through Fisheries Division.
One clerk worked full time to collect angler survey data. Both weekend days and 3 randomly
selected weekdays were selected for sampling during each week of the survey season. No
holidays were sampled. Clerk followed a randomized count and interview schedule. One of two
shifts was selected each sample day. The entire water body was sampled each day. Starting
location within Brevort Lake and direction of travel were randomized for both counting and
interviewing. Two counts of boat, dock and shore anglers were made per day. Survey period for
both counts and interviews was June 1 to September 30. Months were estimated separately.
Estimates are given in the following tables.
