Hydrilla Library

This collection of resources on hydrilla links to key information such as webinars, press releases and documents on aquatic plant management.  Links to many of the items can also be found in context on the other hydrilla webpages.  Some  file sizes are quit large. Since half of the Internet connections in Tompkins County are dial-up, large file sizes are usually noted. The sections include:

• Hydrilla in Cayuga Inlet
• Press Releases about Hydrilla in Cayuga Inlet
• General Information about Hydrilla
• Information about Aquatic Weed Management in General
