Hydro Gate® stop logs are used for level control in open channels.

Logs are beams inserted in grooves cast in a channel wall. Typical nominal height of a stop log is in 6 inch increments, i.e., the log can be 6, 12, 18 inches in height, etc. Hydro Gate aluminum stop logs have rubber lip type seals on each side (end) to seal at the wall and across the bottom to seal at the sill or with the next log. The typical aluminum stop log is equipped with lifting lugs for use with a lifting beam. The beam is a self-engaging log handling device for underwater retrieval and manual lanyard release of the log.
