Under The Ice

On February 26, Nick Stasulis and Charlie Culbertson visited USGS station 01054200 Wild River at Gilead, Maine to make a streamflow measurement through the ice. For these measurements, 20-30 holes are drilled through the ice and a current meter (the spinning yellow cups) is used to measure velocity. River depths and distance across the channel are also measured. After this measurement, this video of the current meter under the ice was obtained, including a great view of the channel conditions.
