Kotlik Shoreline & Water Level Monitoring

A time-lapse camera and tide staff were installed in 2017 at Kotlik to monitor both shoreline change and flooding. Installation was funded by Alaska Institute for Justice and Alaska Ocean Observing System, continued monitoring is being completed by the Native Village of Bill Moore's Slough.

Water levels have been reported on the Alaska Water Level Watch Facebook page. Shoreline monitoring has been conducted using a tape measure from stakes installed and surveyed by DGGS. These measurements have been taken at three locations along the river bank, including sites named: ANTHC Yard, Chris's Site, and AC Hardware.
