UMW - Umatilla R Recycled Water Fac

Status:   Active - Operational
Site Type: Instream Remote Detection System  |  Organization: U.S. Fish and Wildlife Service
General Operational Period: Year Round
Start Date: 1/9/2018 12:00 AM

UMW is an instream detection array in the Umatilla River adjacent to the City of Hermiston’s Recycled Water Plant. One row of three antennas are laid in a pass over orientation, covering most of the wetted width of the river at base flows. In August of 2022, antenna 4 was moved to the antenna 1 spot and antennas 3 and 4 were replaced with newly built antennas. The antenna 2 spot was not replaced and is now empty. Each antenna has a submerged IS1001 node which are connected to an onshore IS1001-MC. The site is grid powered and operates year-round.
