As part of Channel 10’s series on the Erie Canal, Genesee RiverWatch weighed in on a topic most people haven’t thought about: The effect of the Erie Canal on the water quality of the Genesee River.
Watch the Channel 10 segment here:
This topic was recently addressed at the Genesee River Basin Summit by Dr. Joseph Makarewicz. For more than a century, the Genesee River and the Erie Canal have exchanged water at a point on the southern edge of the city of Rochester where the two waterways meet. Eastward-flowing canal water is pushed north into the Genesee while northward-flowing river water is pushed east into the canal.
Water quality in the Genesee has been studied thoroughly, and the impacts of erosion, farmland runoff, septic systems, and sewage treatment plant discharges have been well-characterized. But the impact of the water from the Erie Canal on the Genesee’s water quality hasn’t been carefully examined – until now.
Two researchers from SUNY-Brockport, Lindsay Donahoe and Distinguished Professor Emeritus Joseph Makarewicz, have just published a study that quantifies the impacts of the confluence of a man-made canal and a natural flowing river. Joe, a longtime Genesee RiverWatch board member, presented their findings for the first time at Genesee RiverWatch’s 2025 Genesee River Basin Summit.
Genesee RiverWatch hosted its annual Genesee River Basin Summit on Wednesday, May 28, 2025, at the RIT Inn and Conference Center. The topic of this year’s Summit was “Emerging Issues”. Approximately 100 stakeholders, experts, and community members participated in vital discussions on Emerging Issues affecting water quality and recreation in the Genesee River Basin. It was a unique opportunity to learn about critical topics impacting our watershed and to participate in meaningful conversations that can drive positive change. In addition to the presentations, 10 organizations exhibited their work on subjects such as recreation opportunities and improving the environment.
Each year at our Summit, the Elizabeth Thorndike Award is given to individuals, organizations, projects, or events in recognition of significant contributions to our mission of “championing solutions that improve the water quality of the Genesee and initiatives that connect people to the River”. This year’s honor went to Kaeti Stoss, Environmental Education Specialist at RIT. Congratulations, Kaeti!

After a very successful 2024 paddling season, our summer paddling season is underway. Since 2018, Genesee RiverWatch has partnered with the Genesee Waterways Center and the City of Rochester to offer this summer series of on-the-water kayak paddles. We feel strongly that the best way to really appreciate the Genesee is to explore it from water level, along with the herons, turtles, muskrat, mink, and occasional eagles that make their homes on the river and its banks. We have scheduled the following events in partnership with the Waterways Center and the City Recreation Department. Click here to register on the Genesee Waterways website. Pre-registration is required.
Stay tuned to our social media pages for more paddle event information as the dates get closer! (Paddle dates are subject to change.)



On December 20, 2024, New York State Department of Environmental Conservation (NYSDEC) released new proposed water quality guidance values (GVs) that will advance the State’s regulation of the nutrient phosphorus to protect human health and aquatic life in both flowing and ponded ambient freshwaters. Comments were requested and GRW submitted ours on February 16, 2025. Genesee River Watch has been advocating for a phosphorus standard for flowing waters for some time and it’s good to see that NYSDEC is moving in that direction. In addition, RiverWatch comments included recommendations on how the values could be applied to new and existing wastewater discharges. See attached document for our detailed comments.

Jon Goehring of local radio station Warm 101.3 recently interviewed our executive director George Thomas about Genesee RiverWatch. Take a listen to this 15 minute recording and learn interesting facts about the Genesee, how to enjoy the river, and Genesee RiverWatch’s work to improve its water quality.

As we bring our 50th Anniversary Year to a close, we are grateful for the community support that makes our work possible. Together, we are having a meaningful impact on the Genesee River and its surrounding communities. That is why we invite you to consider a donation of $100, $250 – or an amount of your choosing – to Genesee RiverWatch. Your donation will be matched through the end of 2024 due to the generosity of Sarah C. Mangelsdorf, President, University of Rochester & her husband Karl Rosengren, Professor of Brain & Cognitive Sciences, University of Rochester.
We launched Genesee RiverWatch 10 years ago, building on 40 years of environmental leadership of the Center for Environmental Information, started in 1974. Our mission: “To champion solutions that improve the water quality of the Genesee and initiatives that connect people to the River.” At the inaugural Genesee River Basin Summit, we presented our film “Restoring Our River, Work Worth Doing”. This short film focuses on the beauty of the Genesee, from its source in Gold, Pennsylvania to Rochester’s harbor and the work needed to preserve and enhance the Genesee for future generations. We stand by the film’s conclusion – this is indeed “Work Worth Doing”. View the film.
In that spirit, your participation in our Year End Appeal will help ensure that we have the funding in 2025 and beyond to continue our work. Any amount is welcome and appreciated! The table below summarizes our 2024 accomplishment and future plans. Our 2024 Newsletter has all the details.
