Golden City & Arapahoe Ditch Company Minutes/Account Book of Mary J. Hyatt
Series 206 (One Volume)
Small book containing meeting minutes of the Golden City & Arapahoe Ditch Company (later the Farmers' High Line Canal) from April 10, 1876 to September 15, 1879, recorded by Secretary A.L. Hyatt. Meetings were held at the brick school house at Ralston Creek. Book also contains the by-laws of the company and some accounting notes. In addition, the book seems to have served as an account book of Mary J. Hyatt with lists of properties for sale; notes held by Mary Hyatt; city, state and county warrants held by her; and warrants bought for T.R. Simmons dated 1890-1893. The relationship of that section of the book to the Golden City & Arapahoe Ditch Company requires further review.
Golden-Littleton Irrigation District Files
Series 205 (1 Small Box)
In 1908, landowners with water rights in the Agricultural and Welch ditches voted in favor of forming a new irrigation district to be known as the Golden-Littleton Irrigation District. The district would be comprised of all land lying between West Colfax Ave. and Bear Creek, and Denver and the foothills. Promoters planned to bring the water of Williams fork of the Grand river on the western slope through the continental divide by means of a three mile long tunnel and then into the Clear Creek watershed. The district was dissolved in 1915. Collection contains petition for organization; meeting minutes of the Board of County Commissioners regarding organization; election notices and results; bonds and oaths of directors; petitions for land exclusion; and dissolution papers.
