Abstract
The 12th Mohawk Watershed Symposium was cancelled due to Covid-19. This abstract volume, which was essentially complete at the time of cancellation, is the record of the meeting that did not happen. Over the years this Symposium has taken on an important role in unifying and galvanizing stakeholders in the watershed. A coalition of invested stakeholders allows us as a group to tackle important issues that affect water quality, recreation opportunities, flood mitigation, and other basin-wide issues. By all measures, 2019 was a big year in the watershed. The historic 2019 Halloween Storm caused significant damage in the upper part of the watershed, especially in the West Canada Creek, East Canada Creek, and a number of smaller tributaries. Aid from FEMA for individual assistance was denied and this has caused considerable distress for those with damaged homes. A major effort this year was the work of the Reimagine the Canal task force. This task force took on a number of issues related to the entire Erie Canal, which was divided into Western, Central, and Mohawk sections. Issues included water for irrigation, invasive species, flooding, and ice jamming. The Mohawk was perhaps the most complicated because the Canal and the main stem of the Mohawk need to co-exist despite change in the watershed. The task force effort included the Mohawk Flood Assessment aimed at evaluating benefits from a number of flood mitigation strategies along the length of the River. It also acted on a separate report on ice jamming in the Schenectady Pool in front of the Vischer Ferry Dam, at Lock E7. The Vischer Ferry Dam (VFD) on the lower Mohawk has been under the spotlight for years - in part for its suspected role in causing ice jams that then can flood the Stockade of Schenectady. The Federal Energy Regulatory Commission (FERC) license is coming up, so NYPA, the dam owner, started the renewal process last year for both the VFD and the Crescent Dam, just downstream. The FERC review process can force significant environmental review of the ways in which dams integrate into the local ecosystem and relate to river hydrology. Meanwhile, the City of Schenectady continues formulating its ambitious plan to use FEMA funds to mitigate flooding in Stockade. The plan moving forward may involve elevating or perhaps moving homes in a managed retreat. This plan is intertwined with mitigation efforts for ice jamming at the VFD because jamming causes back-up flooding that can affect the Stockade. Water quality remains a central issue in the watershed and a growing number of stakeholders are involved in this effort. For a healthy and vibrant ecosystem we need clean water. The health of our waters can only be assessed from hundreds of measurements taken across the watershed by students, educators, and dedicated professionals from SUNY Cobleskill, SUNY Polytechnic in Utica, Union College, Cornell, Schoharie River Center, Riverkeeper, DEC, USGS, and others who have been addressing water quality through research. These critical measurements include quantifying the distribution, source, and fate of environmental contaminants including fecal bacterial, microplastics, nitrogen, phosphorus, and others. Stewardship and education are a critical piece of effective watershed management. Stakeholder meetings such as the Mohawk Watershed Symposium, and local water advocates (including West Canada Creek Alliance, Riverkeeper, and Dam Concerned Citizens) play a key role in identifying problems, educating the public, and effecting change where it is most needed. Youth education programs centered on water quality and ecosystem health, such as the Environmental Study Teams at both the Schoharie River Center and Fort Plain High School, insure that all our waterways pass into the hands of the next generation of active, engaged, and knowledgeable stewards. The meeting this year would have featured approximately 30 presentations covering a wide range of topics. We were delighted to see so many familiar names and we welcome those new to the Mohawk Watershed Symposium. We will be back as soon as possible.
