Beginning in 1984, surface float <br />velocities were taken times 0.8 per Brakensiek and others (1979) "Field Manual for Research in Agricultural Hydrology" end Buchanan and Sumers' <br />1968) "Discharge Measurements at Gaging Stations". Since August of 1986, velocities ere measured with an electronic flow meter (Narsh•MCBirney). <br />
