The U.S. Fish and Wildlife Service announced today that nearly $600,000 will be awarded to nine projects targeting three of the highest priorities from the Quagga-Zebra Mussel Action Plan for Western U.S. Waters (QZAP). Colorado and Montana are slated to receive some of the funds for early detection monitoring of water bodies at high risk for introduction and the development of a containment procedures manual for waters that have young or adult mussels.


“As quagga and zebra mussels spread to the Western United States, they can have devastating ecological and economic impacts as already seen in the east and central United States. We must address the spread of these invasive aquatic species, which threaten our Nation’s natural resources, water delivery systems, hydroelectric facilities, agriculture, and recreational boating and fishing,” said Ken Salazar, Secretary of the Interior.


Invasive species are among the primary factors that have led to the decline of native fish and wildlife populations in the United States and one of the most significant natural resource management challenges. A paper published in 2005 in the journal Ecological Economics estimated the cost of invasive species impacts to be approximately $120 billion each year in the United States. We continue to face enormous economic and environmental consequences as a result of invasive, nonnative species spreading in our waterways and on our lands.


Once established these invasive mussels can clog water intake and delivery pipes and dam intake gates. They adhere to boats, pilings, and most hard and some soft substrates. The mussels negatively impact water delivery systems, fire protection, and irrigation systems and require costly removal maintenance. The spread of quagga and zebra mussels across the West brings the potential to extend devastating impacts into a geographic area already challenged with severe water-related problems.


The QZAP provides a common sense approach to guide collective efforts of those fighting the westward spread of quagga and zebra mussels.


The Colorado Division of Wildlife will receive $40,000 in Service funds and $84,000 of in-kind matching to publish a Containment Procedures for Positive Waters manual to complement the State ANS Handbook. Manual will be available in electronic format to all states for their use and adaptation.


Montana Wildlife and Parks will receive $28,754 in Service funds and $150,702 of in-kind matching to increase early detection in Montana’s waters by strategically sampling 10 high priority waterbodies in Montana.




The Bureau of Reclamation will receive $103,559 in Service funds and $38,250 plus time of in-kind matching to implement a pilot laboratory testing program to determine and improve the reliability of laboratory performance regarding early detection of Dreissena larvae in plankton samples.


The Bureau of Reclamation will also receive $72,236 in Service funds and $32,000 plus time of in-kind matching to address key bottlenecks in the effort to expand early monitoring projects by holding two workshops. These workshops will improve the reliability of laboratory results by developing a standard protocol.

Efforts funded in this round of grants include: 

  • Early-detection monitoring programs for quagga and zebra mussels;
  • Developing a manual describing containment activities in infested water bodies;
  • Refining hot water decontamination methods for watercraft;
  • Refining decontamination methods for wildland firefighting equipment;
  • Pilot laboratory testing program for the early detection of larval mussels;
  • Invasive mussel early detection monitoring methods and quality assurance workshops;
  • Creating and implementing uniform minimum protocols and standards for watercraft interception and decontamination programs; and
  • Developing standard and effective equipment (non-watercraft) inspection and decontamination protocols.


The Service also has provided support for quagga and zebra mussel efforts through regional projects under the 100th Meridian Initiative (, a cooperative effort between local, state, provincial, regional, and federal agencies to prevent the westward spread of zebra/quagga mussels and other aquatic nuisance species in North America. In addition, the Service through the Aquatic Nuisance Species Task Force, has funded implementation of State and Interstate Aquatic Nuisance Species Management Plans. These plans describe detection and monitoring efforts of aquatic nuisance species, prevention efforts to stop their introduction and spread, and control efforts to reduce their impacts.
