5203 |a"The sockeye escapement to Sproat Lake in 1979, estimated on the basis of partial visual counts, was 76,446. The estimated escapement to Great Central Lake, based mainly on counts obtained from an automatic counter, was 263,995. Entry of sockeye into Sproat Lake began and ended about 2 wk earlier than at Great Central Lake; at both locations peak periods of passage were associated with high water levels in early July and early September. Diurnal migration patterns differed at the two counting sites. Peak passage generally occurred earlier in the morning at Great Central Lake than at Sproat and the proportions of the daily runs passing at night reached much higher levels at Great Central Lake. The considerable variation in diurnal migration patterns at both locations was not completely random and allowances were made for this when making estimates based on partial visual counts. Some observations on the passage of other salmon species were also made"--Abstract, page v.
