Power Analysis for Long-Term Monitoring of Fishes in Selected Waters of the Gila River Basin, Arizona

摘要

Completion of the Central Arizona Project (CAP) in 1993 allows the potential transport of non-indigenous fishes and other aquatic organisms from the Colorado River, where the CAP network of canals originates, to central and southern Arizona. A U.S. Fish and Wildlife Service (USFWS) Biological Opinion (BO) on transportation and delivery of CAP water to the Gila River Basin (USFWS 1994) determined that the project would jeopardize continued existence of 4 threatened or endangered fishes: Gila topminnow (Poeciliopsis occidentalis), spikedace (Meda fulgida), loach minnow (Tiaroga cobitis), and razorback sucker (Xyrauchen texanus).
