Project 1 Technical assistance with the implementation of the Interagency Monitoring Action Plan (I-MAP) for Quagga Mussels is ongoing. During this quarter, analysis was completed for 42 juvenile/adult samples and analyses of the remaining samples are underway.

The Interagency Quagga Mussel Meeting was held on 05/17/11; the next meeting is scheduled for 08/25/11. Project 2 Appendix 7, an addition to the Long-term Limnological and Aquatic Resource Monitoring and Research Plan for Lakes Mead and Mohave, has been completed and is under review. All associated deliverables from NPS project partners are continuing to be collected for a close-out report to SNPLMA on all Water 2025 Conservation Initiative-funded projects (Rounds 4, 5, and 7); this quarter focused on drafting the narrative portion of the report. A draft interagency quagga mussel needs statement was prepared and will be available for review at the next Interagency Quagga Mussel Meeting. The project group is contributing to the NPS-funded U.S. Geological Survey Circular Report on the science of Lakes Mead and Mohave. Interagency Monitoring and Research Coordination Meetings were held on 4/14/11 and 6/16/11; the next meeting is planned for October
