>) ~""'" ''ti)) a. "A Proposal to Determine Effects of Controlled Flood on the Aquatic Ecosystem if the Colorado River Downstream from Glen Canyon Dam, Arizona" provides a pre -, during, and post-test flow plan for aquatic resources (Persons 1995). b. Additional plans have been developed for the physical and biological resources affected by the test flow under the coordination the GeES. c. SALVAGE PROTOCOL. Humpback chub specimens found dead, or taken as part of research activities, will be turned over to Arizona Game and Fish Department (AGFD) for investigation of food habitats or parasites, and then deposited in the collection of fishes at Arizona State University. 2. A report of the results of the monitoring, including complete and accurate records of all incidental take that occurred during the course of the project, will be submitted to the Service the same date that a draft and final is submitted to Reclamation. Progress reports provided to Reclamation will also be provided to the Service. This report will also describe how the terms and conditions of all reasonable and prudent measures in this incidental take statement were implemented, including any deviations from the test flow and explanation for need to change. 3. The reasonable and prudent measures, with their implementing terms and conditions, are designed to minimize incidental take that might otherwise result from the proposed action. With implementation of these measures the Service believes that take will be minimized and will not exceed 25 humpback chub found floating dead in mainstem or no native fish from the 1995 year class will be found in nearshore habitats above RM 73. If. during the course of the action, this minimized level of incidental take is exceeded, such incidental take would represent new information requiring review of the reasonable and prudent measures provided. The Federal agency must immediately provide an explanation of the causes of the taking and review with the Service the need for possible modification of the reasonable and prudent measures. Kanab Ambersnail AMOUNT OR EXTENT OF TAKE The Service anticipates that as much as 17 percent of the Kanab ambersnail habitat in Grand Canyon could be taken as a result of this one time proposed action. The 10 percent incidental take level remains with the return to normal operations. This translates to approximately 129m2 of the population's primary habitat. Based on impacted area and anticipated snail densities, approximately 640 individuals are expected to be directly affe~leJ by this project. The incidental take is expected to be in the form of harm, harass, mOrralil\ during salvage, and death. Biological and Conference Opinions Glen Canyon Beach/Habitat-Building Flows 2/16196 ,.
