November 2021 – Sampling is done for the year and the results are in. You can read about it in our latest post, hear about the year in a 4-minute video, or get all the details in an informative summary by Emily White, PhD, of Bard College.

And November is also the time of year when we pay the lab at Bard College for the cost of our sampling. We’ve just written a big (for us) check for 2021 costs, why don’t you give us just a little to help out. A donation of just $40 will pay for three months of sampling at one of our sites.

Welcome to the online home of the Roe Jan Watershed Community. We’re here to monitor and enhance the Roeliff Jansen Kill, an important tributary of the Hudson River, mostly in southern Columbia county. The Roe Jan flows through the Columbia County towns of Hillsdale, Copake, Ancram, Gallatin, Clermont, Livingston, and Germantown, and one of the Roe Jan’s larger tribs flows through Pine Plains in Dutchess County.

The Roe Jan Watershed Community started as a citizen-science project to sample the Roe Jan, so we would have a better idea of its condition. Using Riverkeeper for guidance, and the Bard Water lab for assistance and testing, and with strong support from the Columbia Greene chapter of Trout Unlimited, the first sampling was in May of 2016 and continued monthly for five more months. In 2016 we sampled fourteen sites along the 50+ mile length of the Roe Jan, from north of Hillsdale all the way to the mouth of the Roe Jan, in between Germantown and Livingston, including 3 sites on the banks of the Hudson. In 2017 we added several new sites, and initiated Student Sampling Day in May.

If you care about the environment in southern Columbia County (NY), please use the “Get Involved” link at the top of this page to let us know.
