We speak for the river.
We are are on-the-ground advocates protecting the right to clean water in our communities by patrolling local waterways, organizing environmental clean-ups, and educating the public, We take on polluters in the courts of law and public opinion.
We educate future stewards.
We conduct annual environmental education programs, camps, and field trips for middle and high school students to engage in ecological science through experiential learning.
We get people involved.
We organize volunteer task forces to join in our water monitoring programs, the results of which keep thousands of people abreast of water quality in their communities.
What We Do
We monitor and patrol over 8500 square miles, throughout the lower Susquehanna watershed.
In May 2024, 700 middle and high school students experienced the river on our field trip educational program.
Since 2009 LSRA and its volunteers have removed over 230 tons of plastic tires and trash from our waterways.
In 2023 our supporters took action on our advocacy alerts to send 3,460 email messages
In a typical year our riverkeepers and volunteers collected over 400 water samples from different areas of our territory to analyze for a wide range of pollutants.
Since 2017 LSRA has been a plaintiff in 9 legal cases and has secured over $2,000,000 in penalties from polluters.
