Where in the Western United States have Dreissenid Mussels been introduced and where are the populations increasing? Reclamation received ARRA funding for a Dreissenid mussel early detection program for the most vulnerable Reclamation reservoirs and facilities. The program sponsored systematic testing for approximately 329 Reclamation reservoirs and connected waters from 2008 through 2010. During this period, Reclamation has developed a very strong early detection program utilizing cross-polarized light microscopy, scanning electron microscopy, Flow Cam, and DNA testing. The capability to detect the earliest stages of potential mussel infestation at our reservoirs, allows facility managers to make budget and management decisions in the best interest of Reclamation Facilities. Invasive quagga and zebra mussels pose a significant threat to the costs of operation of Reclamation dams, power plants, pumping plants, and other water infrastructure. The aim is to detect the earliest stages of mussel exposure or infestation at Reclamation reservoirs, so that response planning and budgeting for protective measures can be initiated. The purpose of this proposal is to secure funding for the Reclamation Mussel Detection Laboratory in Denver.
Need and Benefit
The two Dreissenid species currently found in the United States have a life cycle that ranges from microscopic larvae to thumbnail size adults, and both have the ability to adapt to extreme environmental conditions. Reclamation facilities were not built and designed with redundant systems, which would allow operations to continue in the event that an invasive species such as the mussels were introduced. Therefore, this invasive species has the ability to disrupt facility operations. Based upon experience with zebra mussels in the eastern U.S., if mussels are detected early, facility operators may have three to five years to plan, budget, and implement protective measures before the population of mussels are large enough to clog pipes, water intakes, drains, gates and trashracks, and thereby impair generation of hydropower and delivery of water. In order to stay ahead of mussel infestations and to help guide preventative and mitigation measures, Reclamation began a monitoring and detection program for many of its reservoirs determined most at risk of mussel exposure and infestation. The aim is to detect the earliest stages of mussel exposure or infestation at Reclamation reservoirs, so that response planning and budgeting for protective measures can be initiated. If microscopic mussel larvae are detected early in a reservoir, potentially several years may be available for response actions to be taken prior to full infestation of facilities. Early actions may also be taken to prevent the spread of mussels to other water bodies.
Results will be reported to the Regional and Area offices on a monthly basis. The state ANS Coordinators will then be sent the result reports. Total counts will be reported to the R&D Office as requested and kept on file at the end of each fiscal year.
Milestones as follows:
FY2013 Milestone 1: Detection method improvements for all test methods.
FY2013 Milestone 2: Results from 2012 program will be used for the 2013 planning.
FY2013 Milestone 3: A Summary report of the program during the 2013 season will be delivered to the R&D Office.
FY2014 Milestone 1: Detection method improvements for all test methods.
FY2014 Milestone 2: Results from 2012 program will be used for the 2013 planning.
FY2014 Milestone 3: A Summary report of the program during the 2013 season will be delivered to the R&D Office.
