Purpose
To show how available
building lots can leverage
renewable power from the dam
to promote:
1. New Business
Development
Attract new business
development opportunities to
the area.
3. Value-Added
Development to Support
Existing Local
Agricultural Businesses
Allow for the development of
value-added opportunities for
existing agricultural industries.
2. Alternative Energy
Technology Research and
Development
Attract federal, state or other
research and development
funding opportunities
Hydrogen Fuel Production Facility
• Generate hydrogen fuel with renewable hydroelectricity instead of
natural gas or other fossil fuels.
• Modeled after the proposed hydrogen fuel production facility on the
Chubb River in Lake Placid, New York.
• Potential to save thousands of dollars on gasoline and employ Croghan
residents to maintain both the H2 production and hydropower facilities.
Flywheels: Federal R & D $$
Available for Energy Storage Technology
A flywheel is essentially a generator in reverse; a steel rotating disc with
magnets on its edge spins on magnetic bearings within a vacuum. The
reduced friction allows for the flywheel to efficiently store energy and
quickly recharge.
• Good system with intermittent power sources (hydro) or industry
demand (i.e. day time vs. nighttime operations): Flywheel bank will
equalize power output between higher and lower flow rates.
Maple Syrup Facility
Lewis County maple farmers are currently largest maple producers in
NYS, yet enormous untapped resources & potential for increased revenue
with use of renewable energy/ energy efficient production options.
Example: Reverse osmosis technology powered by hydroelectricity.
• Electric system cuts process down to ~1/5 of traditional energy inputs
• Hydro electric allows for product to remain sustainable/inexpensive
• Opportunity for cooperative = several producers or one large scale
operator = equipment cost sharing
• More economically feasible to tap more trees & produce more syrup.
Results Provide some specific examples in each of the three general
development scenarios:

Conclusions • Potential for social, economic, and
environmental benefits all rely, first the
dam being saved from the DEC’s proposed
removal and, second utilizing hydroelectric
power on site.
• All provide state-of the art development
through energy efficient technology.
• Provide economic benefit to the Croghan
area.
• Could be used as a baseline for other small
dams in the state/country.
• Potential for growth & sustainable
evolution; investing in this site could be a
monumental step for the rural areas of New
York State and the country as a whole.
NYS DEC Dam Inventory shows enormous potential for
revitalizing NYS dam infrastructure and increasing
renewable energy capacity without building new dams.

ASSESSMENT BASELINE =
Rebuild Dam + Install Hydropower
Abstract As finding cleaner, domestic energy sources becomes more important,
some argue we need look no further than the 1000+ small overflow
dams sitting at the heart of towns and villages throughout the
Adirondack region.
This study encompasses an analysis of potential development
strategies and scenarios for small overflow dams, using the Croghan
Dam, in Croghan, NY as a case study.
After a period of initial research, it was determined that finding funding
to simply rebuild these dams was not a likely scenario, therefore:
• A more holistic approach was adopted, refocusing attention on a
more broadly-defined development strategy, highlighting the
economic potential of the entire dam “site”.
• Deemphasizes the actual dam reconstruction and focuses on
facilitating, wherein dam reconstruction offers the unique
opportunity to incorporate “free”, “green” power and electricity
generated into all business development models.
Methods 1. The SLU Energy & Environment class taught by Dr. Amanda Lavigne traveled to Croghan in September 2010 to assess the dam site.
2. Met with Glen Gagnier, former mayor of Croghan and member of the Lewis County Development Committee (LCDC): a grass roots
organization working to save dam from scheduled removal by DEC & Croghan Island Mill from closure due to the loss of free hydropower.
3. Worked with LCDC on project highlighting recommendations for possible development options following repair of dam.
4. Through meetings with member of the LCDC, the SLU students created a three scenario development model.
5. Study was presented to the Croghan community and local officials on December 7, 2010 at the Croghan Maple Syrup Museum.
