Full Exclusion Guide Nets 

Pacific Netting Products was invited to bid on the manufacture and supply of a new barrier net for the Lower Baker Dam in 2011. The full-depth exclusion guide net works “like an extension of the shoreline” said one agency biologist. The success of these high-tech barrier nets has been proven in fish passage counts, installation and maintenance cost, and in customer satisfaction. Following PSE’s investment in fish passage improvements, by June of 2014 over one million downstream migrating salmon were collected and returns of sixty to one hundred thousand adult fish are soon expected.
