    2014/15 Quagga Grant Funding Summary


    The Legislature enacted Harbors and Navigation Code, Division 3, Chapter 5, Article 1.3 Sections 675 and 676, which became effective January 1, 2013. The statute requires, “the Department of Parks and Recreation, Division of Boating and Waterways, (DBW) to adopt emergency regulations to prescribe procedures for the collection and use of the quagga and zebra mussel infestation prevention fee”.  The statute also requires, “[t]he emergency regulations shall include rules for administering the grants awarded pursuant to Harbors and Navigation Code, Section 676”. These funds were deposited into the Harbors and Watercraft Revolving Fund and will be distributed, upon approval of the project application, as a grant to any person, or federal, state, or local agency, district or authority that owns or manages a reservoir who implements a prevention plan according to statute.

    The Proposed Text for the Permanent Rulemaking (Proposed Text) shall also include rules as to the implementation and administering of the fees through dreissenid mussel monitoring, inspection, and infestation prevention programs implemented by manager/owners of a reservoir pursuant to the Harbors and Navigation Code.

    Funding is available through the grant program to eligible managers and owners of a “reservoir” that is open to the public and NOT infested with dreissenid mussel. Pursuant to  Water Code, Section 6005.4, a “reservoir” is defined as “any reservoir which contains or will contain the water impounded by a dam”. Pursuant to Water Code Section 6002. "Dam" means any artificial barrier, together with appurtenant works, which does or may impound or divert water, and which either (a) is or will be 25 feet or more in height from the natural bed of the stream or watercourse at the downstream toe of the barrier, as determined by the department, or from the lowest elevation of the outside limit of the barrier, as determined by the department, if it is not across a stream channel or watercourse, to the maximum possible water storage elevation or (b) has or will have an impounding capacity of 50 acre-feet or more.

    2015/16 QZ MUSSEL PREVENTION GRANT APPLICATION INFORMATION contains materials and information for the preparation and submission of an application.


    The mission of DBW is to provide safe and convenient public access to California’s waterways and leadership in promoting the public’s right to safe, enjoyable and environmentally sound, recreational boating.


    As part of its mission, DBW manages the QZ Mussel Prevention Grant Program, which will provide funding to programs and aide in the infestation prevention of the dreissenid mussel in California reservoirs.

    The potential savings to the State due to prevention and education efforts provided through the grant program could avert significant damage to the water delivery system. that provides drinking water to millions of Californians, or damage to the irrigation network that supports a $30 billion per year agricultural industry, and could produce extraordinary economic and social consequences.

    Priority is given to dreissenid mussel infestation Prevention Plans that are consistent with Fish and Game Code, Section 2302, which also takes into consideration the benefits of a regional-scale dreissenid mussel infestation Prevention Plan such as:

    • Assessing the vulnerability of the reservoir for the introduction of non-native dreissenid mussel species by, but not limited to:

    1)  Monitoring the number of visitors
    2)  Inquire as to the origin of visitors (relative to dreissenid infested waters)
    3)  Monitor outside equipment that is allowed (rentals)
    4)  Survey the duration of use (day-use, slipped/moored)
    5)  Monitor access (managed or unmanaged)
    6)  Prevention efforts being implemented
    7)  Education efforts being implemented

    • Develop and implement a program designed to prevent the introduction of non-native dreissenid mussel species by including, at a minimum, all of the following:

    1)  Public Education consists of handouts, flyers, signage, postings and verbal communication and education.
    2)  Monitoring consist of applying substrate and plankton tows equipment for monitoring the adult and/or larval mussels.
    3)  Management of those recreational, boating or fishing activities that are permitted which shall include, but not limited to; inspections, decontamination stations and/or information where to decontaminate a vessel, exit inspections and banding of vessels to trailers.
