The Heritage Winooski Mill Museum opened in July 1998 as a "work-in-progress" exhibition in a donated gallery and hall space of the Champlain Mill, one of the former textile mills which now also houses shops, restaurants, and offices. A highlight of the hall exhibits is a large panorama of the Winooski Falls mill complex, c.1920, by Louis McAllister. There are also sequential maps of the mills site, 1840-1993. Future hall panels will in include the Yankee and immigrant workforce as well as transportation.

The gallery overlooks the Winooski River. The Chace Mill and some remnants of it's waterpower technology are in full view. Gallery exhibits already installed are: River & Mills with a working power transfer model, The 1927 Flood, Wool Textile Manufacture, At Work in the Mill with photographs by James Detore and others, a huge power loom and short video, "From Wool to Cloth." Additions will include working conditions, child labor featuring Louis Hine photographs in Vermont, and mill products in peace and war. Section labels are in both French and English.

Major support has come from the Champlain Mill, Chace Mills, Woolen Mill, Winooski One Hydroelectric Plant, Winooski Community Partnership, Pecor Family Foundation, Vermont Council on the Humanities under a grant from the National Endowment for the Humanities (NEH), Lake Champlain Basin Program, Oakland Foundation, Florence Gould Foundation, Merchants Bank and Wiemann-Lamphere Architects. Donations, payable to Heritage Winooski, are welcome.
