MEG - Megler Cr.-Col. R. Estuary

Status:   Active - Operational
Site Type: Instream Remote Detection System  |  Organization: Columbia River Estuary Study Taskforce
General Operational Period: Year Round
Start Date: 1/1/2019 12:00 AM

Megler Creek is a 2nd order stream that flows south out of the Willapa Hills into the Lower Columbia River (RKM 13) Estuary. Tidal influence extends approximately 300ft into Megler Creek from the Columbia River. On June 27th, 2017 two 15ft HDP Passover antennas were installed roughly 10ft apart in Megler Creek at the upper extent of tidal inundation. The antennas span the wetted width of the channel, and are configured as separate nodes to provide directional detection/movement of tagged fish. The property is owned by the National Park Service, part of the Lewis and Clark National Historical Park. A transformer and power outlet with a meter was installed to power the set up. The site is manually downloaded monthly to a USB drive; files are stored on the CREST server.
