Maintaining noxious lake weeds is important for the Lake Gaston environment, which protects the health of fresh water fish and plants, as well as other wildlife, pets and humans.
So how do we accomplish this? We study, survey and make recommendations to all local, state and federal agencies concerned with quality of human life, water, pollution, recreation, wildlife, fish and fishing conditions on Lake Gaston.
Grass Carp (Ctenopharyngodon idellus) is a large plant eating fish with a feeding preference for Hydrilla. At approximately 20 fish per vegetated acre, they have been shown to eliminate Hydrilla. When stocked in lakes and ponds, however, grass carp will eat veraciously and have been known to eliminate all green plants. In 1995, approximately 6.5 grass carp per infested acre were stocked into Lake Gaston by the Lake Gaston Weed Control Council; 5,000 were added in 1999. No restocking was done until 2003. We were permitted to add 8 per infested acre in 2003 for a total of 25,392 grass carp. We are requesting the maximum allowed for loss to attrition of 40% or 10,157 in 2004.
The Wildlife departments of North Carolina and Virginia have statutory authority to issue permits for stocking of grass carp into public waters. To help control Hydrilla but protect Lake Gaston from excessive plant removal, the departments have agreed to allow the stocking of grass carp of up to 8 carp per acre of weed infestation in 2003 and to review each year an amount based on attrition or 3 to 5 per acre. This will be determined after a 2004 Fall survey.
Fisheries experts agree that it is necessary to maintain desirable plants in the water to provide food and habitat for fish and other wildlife. If too many grass carp were inserted it would be very costly to remove them and to re-vegetate the lake with desirable aquatic plants. Consequently, the current weed management plan is to conduct an intensive weed removal campaign using appropriate chemical herbicides on targeted noxious weeds. In addition, with yearly reviews, grass carp are to be maintained at approximately 8 fish per infested acre with the assumption that this number can maintain Hydrilla at low levels without damaging native plants.

Note: It is "illegal" to take by any method Grass Carp from Lake Gaston in both Virginia and North Carolina. It is also "illegal" to be in possession of Grass Carp on Lake Gaston in both Virginia and North Carolina.
Due to limited funds available to the LGWCC it is sometimes necessary that Lake Gaston Homeowners seek private treatments for the control of nuisance vegetation along the shoreline bordering their property. The Council has provided the information below to assist Homeowners in choosing an application company for this purpose.
For full guidance, please refer to Dominion Power's Appendix E to their Shoreline Management Plan, which offers guidelines as to how to obtain private treatment. To visit Dominion's site and view Appendix E (a PDF file), please visit the Dominion Resource Website.

North Carolina State University initiated a program to monitor “water clarity” on Lake Gaston two years ago. Because there is a need to measure clarity at so many locations on the lake they requested volunteers to assist. The avenue to volunteers typically runs through the Lake Gaston Association. The LGA did decide to assist NCSU with this endeavor.
Measuring “water clarity” is a very simple method. You are provided with a Secchi disk and asked to lower it into the water once a week and determine the depth at which you can no longer view it. This measurement is recorded and reported to NCSU. This data is plotted and is used to see if there is a correlation between hydrilla growth and turbid water.
It does not matter if you live on the main lake, a cove, or a creek. All of the data is important. The coordinator for this locally is Bruce Johnson. You may contact him via email should you have questions or would like to volunteer for this program: firstname.lastname@example.org.
