An inexpensive anchor system was designed and used at numerous sites in the forebay of John Day Dam for the purpose of charting river currents during outmigration of juvenile salmonids. This system allowed for the removal of a current meter from the water for periodic maintenance and data retrieval while the anchor remained in a stationary position on the bottom. The anchor system functioned satisfactorily during the 2‐year study.
