The Lake Jeff Conservation Association

Non-Profit Organization

About Us

We are an association made up of a group of residents along Lake Jefferson and others in our area who care about the preservation of the lake. Our mission is to save the lake by repairing the dam and to conserve and restore the environmental, recreational and flood management qualities generously provided to us by Lake Jefferson for the benefit of all residents of Jeffersonville, NY.
Lake Jefferson was created by a dam built in 1927 so the village bathers could romp at and recreate in the shadow of the Lake Jeff Hotel, one of the crown jewels of Jeffersonville until its closing in 1998. Four years later, in 2002, fire burned the hotel to the ground.
During a severe flood in 2006, the spillway face at Lake Jeff was partially shorn away. Following the flood and state of emergency, a costly and extensive repair was done on the dam. The sheer force of the flood waters had scoured out a cave underneath the toe of the dam spillway; it was considered the priority one danger. The repair took place over two construction seasons and involved divers, drillers, industrial-sized pump-out operations above and below the spillway, professional engineers, government engineers, dozens of volunteers, two cement mixers pumping concrete from the Swiss Hill side and Route 52 side and many thousands of dollars in materials and concrete. This was just one of a number of very significant and costly repairs and spillway resurfacings that have taken place over the life of the dam and spillway. And unfortunately, further costly repairs are needed.
In order to ensure the survival of Lake Jefferson, please visit our donation page and consider a tax-deductible contribution. We cannot do it without your support.

Save the Lake

Rebuild the dam

Estimates from multiple engineering firms have put the cost of the repair at around at least a $200,000, and likely higher. An initial engineering study is needed to assess the structural integrity of the dam and watershed model of the lake. We are working with the current owners of the dam to take ownership so that we as a non-profit organization can apply for grants to help fund the repair (something the current private owners cannot do). Once the repair is complete, we will be required to periodically have an engineer inspect the dam to ensure it remains in good condition. All of this will require a large initial funding, and smaller ongoing funding.
The East Branch of the Callicoon Creek is a stocked and native trout stream, home to the American Eel as well. Ensuring that fish and eel are able to bypass the dam is an improvement we may be required to construct as part of dam repair also.

As a lifelong New Yorker with a naturalist inside, Raphael Rosenbaum has always stove to find balance in his surroundings. As a homeowner on Lake Jeff Raphael and his wife Anastasiya were drawn here by the beauty of the rural setting and sense of community.
With an BA in Environmental Studies from the University at Buffalo and completing an MS in Environmental Science from Brooklyn College, Raphael has often worked with regulatory agencies as an environmental scientist and project manager on a variety of environmental cleanup sites.
Preserving this dam and lake are a calling that the history of this Village and the legacy of Lake Jeff deserve, and Raphael is honored to serve on the board of the LJCA.

It was upon her return to the States in June of that year that she was struck with the need to try to help out Main Street in Jeffersonville. One business quickly grew into six and the past four years have been among her most rewarding to date.
