HELP THE PLA GET RID OF WATER CHESTNUT PLANTS IN THE LAKE!
Invasive Water Chestnut Removal
Water chestnut, also known as Trapa natans, is an invasive aquatic plant that can cause many problems for the environment and humans.
Environmental impacts
Water chestnut's dense mats can shade out native plants, which can reduce biodiversity and food and shelter for native fish, waterfowl, and insects. When the mats decompose, they can reduce oxygen levels and sometimes kill fish. The mats can also heat the water, which can impair fish survival.
Human impacts
Water chestnut can make it difficult to use boats, kayaks, canoes, or swim in infested areas. The sharp fruits of the plant can also cause painful wounds if stepped on. Property values along shorelines may also decrease.
Sanitary problems
Water chestnut mats can collect organic waste, which can create water pollution hazards and breeding grounds for mosquitoes.
Pulling out water chestnuts via "hand-pulls" (ie, simply pulling it out of the lake) is best held during the summer when their floating rosettes are present but before their fruits ripen and lower to the sediment - typically from late June through early August. Pulls can be done from a boat, canoe, kayak, or small motorboat
The PLA Board thanks everyone who is pulling out the water chestnut and would ask for your continued effort to rid the lake of this invasive plant.
Thank you for your help!
