Water levels and discharge have been measured at Imnavait Creek since 1985. The drainage is gauged just upstream from the culvert underneath the material site / Alyeska pipeline road, which can be accessed from Dalton Highway MP290.5. The watershed area at the gauge site is 2.2 km2. This gauging site was initially installed as an H type flume, but later the flume was replaced with a trapezoidal weir (with a v-notch). Manual discharge measurements are made at least daily during spring breakup, and a stage-discharge relationship (rating curve) is used to estimate runoff during the summer months. Summer discharge is manually measured 2-3 times per year to verify the rating curve. River stage is measured with 1) automated pressure transducers and 2) manual staff gauge readings.
