The papers of Nancy Papish document her involvement with Clearwater, North River Friends of Clearwater (NRFC), and the campaign to stop Hydro-Quebec's development plan for James Bay. These papers document the environmental activism of Nancy Papish from the 1970s through the 1990s. Included are meeting minutes, notes, mailings, press releases, news clippings, magazine articles, programs, and publications. The Clearwater files contain near-complete runs of newsletters produced by both NRFC and the parent Clearwater organization. Evidence of NRFC's outreach activities is found in a slide show titled "This Is Clearwater" and numerous poster displays. Documentation of Clearwater's organization and administration, such as meeting minutes, internal reports, and committee files, are almost entirely absent. There is little information about the membership of Clearwater. The James Bay files contain materials from several organizations.
