1Q=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 Brakensiek and others (1979) "Field Manual for Research in Agricultural Hydrology" and Buchanan and Sumers'
1968) "Discharge Measurements at Gaging Stations". Since August of 1986, velocities are measured with an electronic flow meter.
