<br />Yn joint partnership with the U.S. Fish and <br />Wildlife Service and the Colorado River Indian <br />Tribes, the ,-~Cl-ill ~'.~~N~J[=~ Ponds were <br />created to rear endangered razorback sucker <br />and bonytail fish}. Six ponds totaling 14 <br />surface acres were constructed on tribal <br />reservation land with funding and services <br />contributed by the Bureau of Reclamation. <br />The Tribes made the land and water <br />available at nominal costs. This high priority <br />Recovery Plan project has the potential to rear <br />50,000 fish of each species for stocking in the <br />lower Colorado River. Program funds supported construction and initial operations of the <br />ponds. The warm Arizona climate makes it possible to raise more fish in less time than at <br />other locations. <br />documented diverse bat fauna on 275 miles of the <br />Colorado River from Lee's Ferry through Grand <br />Canyon National Park. The project also surveyed 27 <br />different caves to determine bat use, location and size <br />of roosting colonies. <br />Threats to important roost <br />sites were also assessed. <br />Nine bat species not <br />previously known from this <br />range were identified. The <br />report concluded that it is <br />unlikely that serious <br />adverse effects to bat <br />communities have resulted <br />from the construction and <br /> <br />operation of Glen Canyon Dam. Recommendations for protection and management of <br />selected bat caves were developed for consideration by the National Park Service. The <br />"ANABAT" ultra-electronic detector was used to identify bat species at night from their <br />unique flight calls. At upper right is the call of the Mexican free-tailed bat; at lower left the <br />pallid bat. <br />
