Flow is continuously Pe rshall flume w/continuous monitored except during winter (November - recorder (high g=VA, low a=885) February) 1 g=YA means that flow (D) is calculated by multiplying measured stream velocity (V) times cross sectional area (A ); g=B85 means that 0 is determined 2by use of a bucket (B) and stopwatch (S). Up 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 end others (1979) "Field Manual for Research in Agricultural Hydrology" and Buchanan end Sumers' 1968) "Discharge Measurements at Gaping Stations". Since August of 1986, velocities ere measured with en electronic flow meter (Marsh-NCBirney).
