tidegates and self-regulating tidegates
Tidegates are typically one-way culvert placed under a levee or dike that separates freshwater and tidally influenced areas. It is designed to open and allow freshwater to drain to the sea during low tide, but to close at high tide.
Self-regulating Tidegates (SRTs) are a kind of tide gate technology that uses a float or another mechanism to detect water level, and delays closing of the tide gate until flood tide reaches a certain level. Compared to a standard tide gate or flood gate, a SRT maintains connectivity between the Salish Sea and tidal channels, purportedly improving water quality and access for estuarine dependent fish.
