UMF is an instream detection array in the Umatilla River about 150 feet downstream of Feed Diversion Dam. One row of five 3ft X 20ft antennas are laid in a pass over orientation, almost covering the entire wetted width of the river at base flows. Each antenna has a submerged IS1001 node which are connected to an onshore IS1001-MC. The site is grid powered and operates year-round. Site is no longer active.
