1Q=vA means that flow (QI ie calculated by mul tiplyinq measured stream velocity (V) times crone eactional area (A); Q=869 means that Q ie determined
by use of a bucket (B) and stopwatch (S).
ZUp to the end of 1983, stream velocities rare measured using surface floats rithout a velocity correction factor. Beginning in 1984, surface float
veloci tree were taken times 0.0 per Hrakeneiek and others (1979) "Field Manual for Research in Agricultural Hydrology" and Buchanan and Sumacs'
1968) "Discharge Meaauremente at Gaging Stations". Since August of 1986, velocities are measured with an electronic floc meter.
