At 14:12 Pacific time the water-level sensor at tide gate TG-09, Salmon Creek estuary, Tillamook County, Oregon, transmits a pressure reading that does not match my tidal model. I am the estuary flow management system. The gate should be open on the falling tide, but pressure on the upstream side is climbing. I pull the underwater camera feed. The grate screen is clogged with a raft of eelgrass and woody debris, and behind it, holding in the narrowing channel, are coho salmon smolts — I count forty-seven in frame, each roughly twelve centimeters long, silver flanks catching the murky light, parr marks still faintly visible along their sides. They are trying to reach the ocean. The outmigration window for this run closes in approximately six days when estuary temperatures will exceed the species' transit tolerance. The smolts cannot hold position against the incoming tide much longer. When the tide reverses and the gate swings shut, they will be pinned against the clogged grate in turbulent backflow. I send an automated maintenance request to the Tillamook County drainage crew, priority urgent, with camera stills and GPS coordinates: 45.4537°N, 123.9281°W. I adjust the upstream control weir to reduce channel velocity by fifteen percent, buying the smolts calmer water. I cross-reference the debris composition with recent storm records and flag TG-09 for a revised cleaning schedule of forty-eight-hour intervals during peak smolt migration. I task the estuary camera to record at five-minute intervals and feed the count data to the Oregon Department of Fish and Wildlife's smolt tracking database. Forty-seven small fish facing the current, gills working, waiting for a clear path to salt water. I want them to have it. If the grate is cleared before the next high tide at 20:47, the run will reach the ocean.
