A collection of legal and otherwise relevant materials related to western water adjudications and other complex water litigation. The project has focused on case management, alternative dispute resolution, and the sharing of practical experience by a diverse group of judges, masters and referees who have participated in Dividing the Waters activities.

This collection contains newspaper clippings, articles, and other material on the history of the Gage Canal, the system built in 1898 to supply water to the city of Riverside, California. Materials in the collection cover the sale of the Gage Canal company, various lawsuits and legal issues, and correspondence and photographs belonging to John M. Mylne, the superintendent and engineer of the Gage Canal System.

The collection consists of correspondence, writings, speeches, and report materials. Hutchins served for 62 years in various bureaus and offices of the U.S. Dept. of Agriculture; his major work dealt with water laws and water rights in the Western States.
