Croghan Island Mill
Why it's listed
On Croghan Island in the Beaver River, a wood-clad mill complex and a concrete dam still turn out lumber products and millwork using water power. The main block, a two-and-a-half-story gabled building on a laid stone foundation, was built about 1875 by the Rice brothers. Later additions include a cold storage block, an office block and a sawdust outbuilding. A wooden water wheel set horizontally beneath the water drives a gear and master belt, which power pulleys in the basement and about a dozen late nineteenth and early twentieth century machines on the floor above. The poured concrete dam dates to about 1906 and replaced an earlier wooden crib dam. The mill was listed because it is a rare, largely intact example of a water-powered sawmill in New York, preserving its building, machinery, power source and island setting. Croghan's economy long centered on lumber and forest products, and the mill reflects that history. The period of significance runs to 1960 because the mill still operates the same way.
Significance in brief: The nomination argues the mill is a rare, substantially intact example of a nineteenth-century water-powered sawmill in New York State. It keeps its exterior, setting and mechanical systems, and still operates commercially on water power. It reflects the water-powered industry that once fed many mills across the state and the lumber economy of Croghan.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
