PNM (Public Service Company of New Mexico) operates a water diversion structure on the San Juan River in Farmington NM. A selective fish passage facility was constructed on the Navajo Nation side of the San Juan River to allow movement of endangered native razorback sucker and Colorado pikeminnow around the PNM weir structure.
Biomark, in conjunction with the US Bureau of Reclamation, Navajo Nation and Utah State University installed a MTS (Multiplexing Transceiver System) with six antennas to monitor the fish passage and a section of the concrete weir wall. The fish passage is monitored by two 20’ X 5’ pass through antennas and 80’ of the weir wall is monitored by four, first ever, 20‘ x 4’ concrete base super stout antennas. The concrete antenna base was developed to be deployed in fast moving water on a concrete surface and to withstand heavy flows and impact from large debris. The data collected at this site is to evaluate the efficiency of the fish passage facility and to provide recapture information to the San Juan Recovery Program for survival and population analyses.
