Water Chestnut Weeds in Putnam Lake
The Park District has initiated hand weed pulling (one of the best methods for removal) of the highly invasive Water Chestnut weed in an effort to eliminate it from our waters. Water Chestnut weeds were located along the entire coastline of Putnam lake and highly concentrated from Hudson and Interlaken Beach to the north end. Water Chestnuts are a highly invasive weed that reproduce rapidly and out-compete native plants for sunlight. One acre of water chestnut can produce enough seeds to cover 100 acres the following year. If uncontrolled, it creates a nearly impenetrable mat across wide areas of water, thus limiting the passage of light into the water. At die off, it reduces oxygen levels, which may increase the potential for fish kills. Water chestnuts also produce spiked seeds that are capable of puncturing shoe leather and pose a danger while launching boats and to beach users when spread to those areas. Fortunately, these weeds are fairly easy to hand pull from any boat or kayak and can be controlled. Efforts on this project will need to continue every summer until all visible plants are removed. Each year's weed pull dramatically reduces the next year’s crop.
