Cayuga Lake Inlet Hydrilla Educational Materials Available

Thousands of boaters heading out onto to the waters of Central New York's Finger Lakesthey are being warned to keep an eye out for an invasive aquatic weed that has the potential to disrupt the region's lake ecosystems and diminish New Yorkers' future enjoyment of boating, swimming, and fishing activities on the lakes.

A coalition of state, regional, and local partners, coordinated by the Cornell Cooperative Extension Invasive Species Program is asking boaters to be part of the effort to prevent the spread of hydrilla from Cayuga Lake to other Finger Lakes and regional inland lakes, as well.

A boaters, whether they have motorized or non-motorized craft need to become educated on the plant and to follow clean boating practices whenever they enter or leave the lake.

  • Avoid running watercraft through areas of densest infestation
  • Remove all plants, mud or debris from boats, trailers, or other equipment that come in contact with water
  • Dispose of this material in trash cans or on land where it cannot be washed into any pond, lake or stream
  • Drain all water from boats before leaving a launch area
  • Clean and dry anything that came in contact with Cayuga Lake water (including your dogs!)

Educational materials including boat launch signs and educational brochures are available for download here:

Hydrilla poses a serious threat to the lake ecosystem because it grows aggressively, creates thick mats of vegetation that choke waterway,shades out native aquatic plants, reduces the quality of habitat for fish, waterfowl, insects and other beneficial organisms, interferes with boating, fishing, and swimming, reduces shoreline property values, and can cost million of dollars to control.
