14=vA means that flow (Q) is calculated by multiplying measured stream velocity (V) times cross sectional area (A); Q=B&S means that Q is determined
by use of a bucket (B) and stopwatch (S).
2Up to the end of 1983, stream velocities were measured using surface floats without a velocity correction factor. Beginning in 1984, surface float
velocities were taken times 0.8 per Brakeneiek and others (1979) "field Manual for Research in Agricultural Hydrology" and Buchanan and Sumers'
1968) °Diecharge Measurements at Gaging Stations". Since August of 1986, velocities are measured with an electronic flow meter.
