001753 37 Protection Act (Section 1802) to "operate Glen Canyon Dam in ... such a manner as to protect, mitigate adverse impacts to, and improve the values for with Grand Canyon National Park and Glen Canyon National Recreation Area were establishl~d," the GCD-AMP seeks to ensure the in- situ preservation of cultural resources with minimal impact to the integrity of those resources. When in-situ preservation is not possible, data recovery through excavation or other mitigation measures as appropriate may be implemented. GCMRC works with the signatories to the Programmatic Agreement for Cultural Resources and their designated representatives, as well as other stakeholders in the AMP, to help devise monitoring and research projects that will assist in the preservation and treatment of National Register eligible properties. In addition, GCMRC is concerned with devising and implementing monitoring and research projects that address the non-eligible resources of traditional importance to Native American tribes who have cultural affiliation with the Grand Canyon. Since 1992, cultural resources have been monitored by National Park Service archaeologists and by tribal representatives (Leap et aI., 2000). The cultural resource monitoring work conducted to date has primarily been carried out in fulfillment of the Programmatic Agreement requirement to provide information for use in developing a long-term Historic Preservation Plan. The P A-driven monitoring activities typically have included repeated visits to archaeological sites, using repeat photography and qualitative observation to track changes in resource condition. Tribal assessments of traditional cultural resources employ many of the same techniques used in monitoring archaeological sit<~s: repeat field visits, repeat photography and qualitative observations recorded on forms. Tribal[ assessments of the overall "health" of the ecosystem are generally based on subjective assessments grounded in traditional perspectives. Cultural resources are monitored routinely and during high flow events. Beginning in FY06, monitoring of cultural resources in the CRE will be redirected to focus on the specific requirements of the Grand Canyon Protection Act, in addition to providing basic condition information to meet the requirements for monitoring under the P A. The former P A monitoring program will be realigned and redesigned to generate data that will improve understanding of the effects of dam operations on these highly valued and largely non-renewable resources and to provide information to the AMP that will be useful in formulating recommendations to the Secretary of the Interior about managing dam operations so as to "protect, mitigate adverse impacts to, and improve" the cultural resource values in the eRE.
