Members of the Lake Anna Business Partnership with Sharonand Greg Shalawylo owners of Billikens BBQ Company at the Once the scourge of the warm side hydrilla has re- turned to the cold side this time. There were three reported locations confirmed by Dominion Resources personnel in 2014. These infestations are small. How- ever hydrilla can replicate itself from just about any portion of its length so boats swimmers or rakes used to clear it out create lots of potential new growth. This current infestation is significantly smaller than it grew into before treatment 20 years ago. Left to itself though it could become a major problem for lake side recreation. Delay in taking action is not our friend. By the time hydrilla was finally treated back in 1994 it had spread over almost 900 acres on the warm side. It created problems for swimmers and boaters. VDGIF Virginia Department of Game and Inland Fisheries approved a permit and Dominion eventu- ally placed over 6000 sterile carp life span - 15 years or longer in the warm side to attack the infestation. Within a year according to several residents who were here at the time the carp ate all of the hydrilla. But then the carp began eating less-favored but avail- able aquatic weeds around the warm side. Gradually the carp spread out over the entire lake indiscrimi- nately harvesting desirable aquatic weeds as well as non-native weeds. This reduced habitat for many other lake creatures. According to VDGIF and Dominion Resources biologists Lake Anna is recovering from this eating binge. Fishing has improved on the lake as native weeds have returned providing cover and food for the lakes fish population. Carp are not the answer to the hydrilla question in all cases and while VDGIF supports carp in ponds on its website it does not support the return of carp into Lake Anna at this time. Evidence from other states has indicated that the use of carp is a hit or miss affair. A study published by the state of Washington stated Sometimes the stocking rate of sterile carp results in no control control or even complete elimination of all underwater plants. ...in 39 of the 98 lakes stocked with carp all submersed plant species were eradicated. It has become the consensus among researchers and aquatic plant managers around the country that grass carp are an all or nothing control option. They should be stocked only in water bod- ies where complete elimination of all submersed plant species can be tolerated. source - www.ecy.wa.gov programswqplantsmanagementaqua024.html The Lake Anna Advisory Committee LAAC a governmental body created by joint agreement be- tween Louisa Spotsylvania and Orange counties has assumed the leadership role in the emerging fight against hydrilla as required by its charter. At a recent meeting the committee reviewed the several options for removing the weed from the lake. Do nothing while always an option this was dis- carded since such a position would allow the infesta- tion to grow. It would only create a larger problem later on as hydrilla continued to spread out from the small sites it is currently found. After all the 900 infested acres in 1997 didnt get infested overnight. Mechanical harvesting this involves the use of machines to cut the weed off at its root and remove it from the infested areas. This method was discarded because there is every likelihood that the weed pieces not collected would only repopulate the infestation and spread it out. Herbicides Unlike during the last infestation to- days herbicides are less of a threat to animals and humans much like the Round-Up product used for spot treatment of weeds on lawns.They are weed- specific and become inert within a short time period a day or so. In addition these chemicals require a state licensed contractor to apply them. This method was chosen for a pilot project on the three sites on the lake. A spot treatment for a spot problem. LAAC approved a pilot with an approximate cost of 2000 not to exceed 5000. Sterile Carp This was determined to be over-kill at this point since the current infestation is small and carp cannot be trained to remain in a single location to eat just the hydrilla. As was quoted above carp could once again remove many desirable aquatic weeds once hydrilla is eliminated. Should the chemi- cal pilot fail this would be the possible fall back. In Florida where the water stays warm most of the year supporting hydrilla propagation a combination of both chemicals and carp is used. As of this writing the pilot is also viewed to in- clude a public awareness program so boaters and swimmers can readily identify the weed and have a means of reporting it. Also since so many boats are launched into the lake over the boating season an education program at lake side marinas is also be- ing considered. The Lake Anna Civic Association www.lakeannavirginia.org will have additional in- formation on this effort. What can you do Learn to identify hydrilla. When you find it write down the GPS location Latitude Longitude and report it to LAAC. The best way to reach LAAC at this point is through this publica- tions email address. They will forward your report to the appropriate party. Remember the issue is time Hydrilla grows fast and spreads easily. Fast spot treatment will allow LAAC and other organizations to quickly assess the best approach for the future.
