Hydrilla - an extremely aggressive aquatic plant - was found in Cayuga Lake adjacent to Wells College in the Village of Aurora in the fall of 2016 and off the shore of King Ferry in 2018. If left unchecked, hydrilla will spread rapidly forming into thick mats of vegetation making swimming and boating impossible as well as negatively affecting fish populations. The impact to the local economy can be significant.
