摘要: Abstract The Central Arizona Project (CAP) canal delivers Colorado River water into the Gila basin. During its planning and construction, issues arose regarding unwanted entrainment transport of nonindigenous fishes other aquatic biota into, through, out canal. One control strategy was emplacement electrical fish barriers on two CAP distributary canals to prevent from moving upstream drainage. operation, maintenance, effectiveness these are described for period 1988–2000. Documented outages totaled more than 100 h, representing less 0.001% downtime since installation. It is nearly certain that allowed immigration by undesired fish(es). Immigrations occurred when were operating according design criteria indicate do not totally block passage upstream-migrating fish. proximate sources barrier outage included component damage lightning strikes...
