Flow is continuously Parshall flume u/continuous monitored except during winter (November - recorder (high O=VA, low G=88SI February). Weekly/triannual water quality. 7 O=VA means that flow (O) is calculated by multiplying measured stream velocity (V) times cross sectional area (A); D=B8S means that 0 is determined 2by use of a bucket (B) end 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 erakensiek and others (1979) "Field Manual for Research in Agricultural Hydrology" and Buchanan end Sume rs' 7968) "Discharge Measurements at Gaging Stations". Since August of 1986, velocities ere measured with an electronic flow meter (harsh-NCBirney).
