Why the Low Flow Test <br /> <br />Introduction <br /> <br />The Test was conducted by Reclamation from July 9-15, <br />2001. Impacts were studied primarily from Navajo Dam to <br />Farmington, New Mexico, although some effects were <br />assessed further downstream, Releases from Navajo Dam <br />were lowered from approximately 500 cfs to approximately <br />250 cfs during this time. <br /> <br />The purpose of the Test was to assess the effect of low <br />summer riverflows on various resources, The information <br />obtained will be used to prepare an EIS in 2002 on <br />operating Navajo Dam to meet Flow Recommendations for <br />designated critical habitat of downstream endangered fish <br />while maintaining authorized purposes of the Navajo Unit, <br />which include allowing for current and future water <br />development. The water development would include, but <br />not be limited to, the Animas-La Plata Project near <br />Durango. Colorado, and completion of the Navajo Indian <br />Irrigation Project near Farmington, New Mexico. <br /> <br />Endangered fish (the Colorado pikeminnow and razorback <br />sucker) and their critical habitat are protected under the <br />1973 Endangered Species Act (ESA), while Navajo Unit <br />authorized purposes are mandated by the 1956 Colorado <br />River Storage Project (CRSP) Act, <br /> <br />Summer Low Flow Test Report - April 2002 <br /> <br />-1- <br /> <br />00590 <br />
