    I never used to be a conspiracy theorist......I'm leaning that way more and more every day. SCDNR aquatic management plan links are "404 File Not Found"
    Listen to your elders. Not because they are always right but because they have more experiences of being wrong.

    . Lake Murray
    (Lexington, Newberry, Richland and Saluda Counties)
    Problem plant species
    Hydrilla, Water Primrose
    Management objectives
    37 SOUTH CAROLINA AQUATIC PLANT MANAGEMENT PLAN
    Minimize hydrilla growth throughout the lake to prevent its spread within the lake, help prevent
    its spread to adjacent public waters, and avoid adverse impacts to drinking water withdrawals
    and public use and access.
    Monitor water primrose growth and consider control options if impacts are greater than
    anticipated.
    Maintain diverse aquatic plant community through selective application of control methods and
    introduction of desirable native plant species.
    Selected control method
    Triploid grass carp – stock 3000 triploid grass carp to rebalance the population after significant
    losses due to opening of the Flood Gates in 2015

    Aquatic herbicides - selected areas of water primrose infestation to provide public access.
    Problem Species Control Agents
    Hydrilla Chelated copper (Nautique)
    Water primrose Renovate 3, Habitat, Clearcast
    Area to which control is to be applied
    Release approximately one-half of the triploid grass carp on the north side of the lake and onehalf
    on the south side.
    Use aquatic herbicides to provide control at high priority public access points, such as boat
    ramps and park sites.
    Rate of control agent to be applied
    Triploid Grass Carp: Stock 3000 sterile grass carp, 1500 in the spring and 1500 in the fall, to
    rebalance the population. (Continue maintenance stocking in future years with 1710 sterile
    grass carp per year to maintain a density of 1 grass carp per 6 surface acres (8333 fish). Continue
    maintenance stocking in 2018 based on conditions. Stock to maintain 1 to 6 surface acres
    density when population dictates and to add different age class fish. 3000 sterile grass carp to
    maintain a density of 1 grass carp per 6 surface acres (8333 fish). The Aquatic Plant
    Management Council is committed to maintenance stocking of triploid grass carp in Lake
    Murray to provide long-term control of hydrilla. The Aquatic Plant Management Council, with
    recommendations from DNR and Lake Murray staff, agrees that the adaptive stocking plan
    should be continued, based on current observations of collected data, Herbicide treatments
    may be utilized to provide temporary control of hydrilla when necessary. Changes to the
    strategy will be implemented if survey results, regrowth, or habitat loss warrant.

    Water primrose treatment:
    Renovate 3 - 0.500 to 0.750 gallons per acre.
    Habitat - 2 to 4 pints per acre.
    Clearcast - 1 to 4 pints per acre.
    Method of application of control agent
    Triploid grass carp - See section 3 above.

    All agents to be applied when plants are actively growing.
    Timing and sequence of control application
    38 SOUTH CAROLINA AQUATIC PLANT MANAGEMENT PLAN
    Additional grass carp should be stocked in the spring/fall following Council approval.
    Apply herbicides to aquatic vegetation as it becomes problematic.
    Other control application specifications
    If needed, all sterile grass carp will be a minimum of 12 inches in length. All sterile grass carp
    shipments for Lake Murray will be examined by the SCDNR for sterility, size, and condition at the
    Campbell Fish Hatchery in Columbia prior to stocking in the lake.

    Control by Residential/Commercial Interests:
    This plan is designed to provide relief from noxious aquatic vegetation for the public at large.
    Private entities such as lake-front residents and commercial interests may have site specific
    concerns not addressed immediately using grass carp or mechanical harvesters at public access
    areas. Residential and commercial interests may remove nuisance aquatic vegetation manually
    or by use of mechanical harvesting devices. Of the three-major control methods the following
    conditions apply.
    1) Mechanical harvesters – Commercial aquatic plant harvesting services may be hired to
    remove hydrilla and Illinois pondweed from areas adjacent to residential and commercial
    property after notification of SCE&G. Harvesting precautions as stated in item above must be
    adhered to.
    2) Aquatic herbicides – SCE&G opposes regular or general application of herbicides in Lake
    Murray, therefore, aquatic herbicides may not be applied in the lake by lake front property
    owners. Label rate of herbicide will be stringently adhered to.
    3) Sterile grass carp - A sufficient number of grass carp have been stocked by SCDNR to control
    nuisance aquatic vegetation. Stocking additional grass carp in Lake Murray without written
    consent by the SCDNR is prohibited.
    Entity to apply control agent
    Triploid grass carp - Commercial supplier with supervision by the SCDNR.
    Aquatic herbicides - Commercial applicator under supervision by the SCDNR.
    Estimated cost of control operations
    Triploid grass carp - $28,000
    Aquatic herbicides - $0
    Potential sources of funding
    Triploid grass carp.
    S.C. Electric and Gas Company, Lexington and Richland Counties 50%
    S.C. Department of Natural Resources 50% (up to $30,000 cost share per waterbody)
    Mechanical harvester, S.C. Electric and Gas Company, Commercial marina operators, and
    residential property owners.

    Aquatic herbicides
    S.C. Electric and Gas Company, Lexington and Richland Counties 50%
    S.C. Department of Natural Resources 50% (up to $30,000 cost share per waterbody)
    (Percentage of match subject to change based on availability of Federal and State funding.)
    39 SOUTH CAROLINA AQUATIC PLANT MANAGEMENT PLAN
    Long term management strategy
    a) Manage the distribution and abundance of nuisance aquatic plant populations at
    levels that minimize adverse impacts to water use activities and the environment
    through the use of federal and state approved control methods.
    b) Maintain or enhance native aquatic plant populations at levels beneficial to water
    use, water quality, and fish and wildlife populations through selective control of
    nuisance plant populations where feasible, introduction of native plant species
    where appropriate, and public education of the benefits of aquatic vegetation in
    general.
    c) Seek to prevent further introduction and distribution of problem species through
    public education, posting signs at boat ramps, regular surveys of the water body,
    and enforcement of existing laws and regulations.
    d) Improve public awareness and understanding of aquatic plant management
    activities through the maintenance of the Lake Murray Aquatic Plant Management
    web site. The web site includes up-to-date information on annual management
    plans, dates and locations of current and historical control operations, locations of
    habitat enhancement activities, and other pertinent information.
    e) Periodically revise the management strategy and specific control sites as new
    environmental data and control agents and techniques become available and public
    use patterns change.

    They must have fixed the links this morning because they are working for me now to. I am starting to think the triploid carp is the South Carolina state fish.

    I hope they do. I haven't seen any Hydrilla out there in a long time.

    What a waste of money.

    Lake Murray has 50,000 surface acres with an estimated area of vegetation coverage of 50 acres. Do the math on this horrible infestation of nuisance aquatic vegetation. .001 % the carp will starve.......unless they eat all of our native vegetation.

    At one time there was a hydrilla problem at Murray, but that has been a while now. I don't remember the last time I've seen hydrilla on the lake, not to mention much in the way of native vegetation. They need to cool off some on the carp and find a happy medium IMHO.
