Records of the North Poudre Irrigation Company
Scope and Contents
The Records of the North Poudre Irrigation Company consists of documents dated 1880 to 2009, with the bulk falling from 1901 to 2005. The company's activities and system are documented through a variety of material types including annual reports, stock certificates, financial records, legal documents, and engineering reports. Voluminous correspondence documents daily operations until the 1970s, but only the first decade of board meetings are documented through minutes. The company also documented facilities and their maintenance and rehabilitation well through maps and plans, as well as with photography starting in the 1970s, along with few but significant images from the earliest years. Other organizations documented include two which merged with NPIC, the Mountain Supply Ditch Company and the Box Elder Ditch and Reservoir Company, as well as groups in which NPIC participated, such as the Cache la Poudre Water Users Association, the Northern Colorado Water Conservancy District, and the Four States Irrigation Council. Beyond irrigation, water management, and engineering, other subjects covered in the collection include land planning, oil and gas extraction, and environmental and community issues in the Cache la Poudre Basin.

Since 1901, the North Poudre Irrigation Company (NPIC) has supplied water to Northern Colorado's Boxelder Creek Valley farmers and ranchers through its system of canals and reservoirs. Today, the company owns nineteen reservoirs and approximately 200 miles of ditches and laterals. Reflecting broader trends in Colorado history, the system provides an increasing portion of its water to municipal users.
In the 1870s, Larimer County residents recognized that an irrigation canal could divert from the North Fork Cache la Poudre River to enable cultivation of the lands north of Fort Collins. Local business owners incorporated a series of irrigation companies that formed and failed in quick succession: North Fork Irrigation Canal Company (1878), the North Poudre, Box Elder, and Lone Tree Canal Company (1879), and the North Poudre Land, Canal and Reservoir Company (1880).
The North Poudre Land, Canal and Reservoir Company used money from eastern investment companies to fund construction of the North Fork Canal (later renamed the North Poudre Canal), but in 1886 Traveler's Insurance Company foreclosed on the ditch and 16,000 acres of company land used to secure the loans. F.C. Grable purchased the renamed North Poudre Land and Canal Company in 1896 but was unable to make the enterprise profitable.
Northern Colorado investors bought the partially-constructed system in 1901 and incorporated the North Poudre Irrigation Company. The company located its offices in Greeley and increased the number of available capital stock shares, using the funds to complete the North Poudre Canal and construct several large reservoirs: Fossil Creek, Halligan, and Reservoir No. 15. NPIC also acquired higher priority diversion rights by strategically selling Douglas Reservoir to the Poudre Valley Reservoir Company and purchasing stock in the Larimer No. 2 Ditch, New Mercer Canal, and Box Elder Ditch and Reservoir Company. These improvements and the water exchanges they enabled spurred farmers to purchase company-owned land and brought about the founding of Wellington, Colorado, in 1903.
In 1912, investors again reorganized the company, which had moved its offices to Fort Collins six years earlier. They increased the number of capital stock shares to 10,000 and reincorporated NPIC as a mutual ditch company. That same year, NPIC merged with the Mountain Supply Ditch Company, originally incorporated in 1905. NPIC then took over the Box Elder Ditch and Reservoir Company in 1916, thus increasing its system substantially in a small number of years.
By the 1930s and 1940s, NPIC worried less about financial viability and more about how to maintain and expand its aging system. During this time, the company was able to rehabilitate some of its facilities with help from the Civilian Conservation Corps. Following approval of the Colorado-Big Thompson Project in 1937, NPIC became the largest holder of C-BT units (40,000 units), which were delivered from the Cache la Poudre River to the NPIC system through the newly-constructed North Poudre Supply Canal (also called the Munroe Gravity Canal).
As the twentieth century progressed, NPIC sought additional control of the water in its system. In 1964, the company moved its offices closer to its shareholders and system assets by relocating to Wellington. In 1970, NPIC upgraded Halligan Dam and constructed a project first discussed in 1905, Park Creek Reservoir, which held water from the North Fork Poudre River. After decades of dealing with destructive flash floods, NPIC partnered with the Soil Conservation Service for the Boxelder Creek Watershed Project. From 1977 to 1982, five flood control dams were built on Boxelder Creek. In 1978, NPIC voted to rehabilitate its entire system of canals and reservoirs, a project the company pursued through the 1980s.
Beginning in the 1970s, NPIC faced increasing pressure from urban development as Northern Colorado's population grew. Subdivisions sprang up along the edges of NPIC reservoirs and laterals. Towns looking to secure water for an increasing number of people began to acquire NPIC shares. Wellington negotiated use of Reservoir No. 3. In 1972, NPIC traded Joe Wright Reservoir and Michigan Ditch to the City of Fort Collins for improved water rights, and in 2004 Fort Collins purchased Halligan Reservoir, though NPIC retained its senior storage right. The transfer of water from agriculture to urban purposes accelerated quickly. Today, NPIC remains committed to its agricultural stockholders, but municipalities use approximately 75 percent of NPIC water.

Language of Materials
Since 1901, the North Poudre Irrigation Company (NPIC) has supplied water to Northern Colorado's Boxelder Creek Valley farmers and ranchers through its system of canals and reservoirs. Today, the company owns nineteen reservoirs and approximately 200 miles of ditches and laterals. The company's activities and system are documented through a variety of material types including annual reports, stock certificates, financial records, legal documents, engineering reports, correspondence, meeting minutes, photographs, and maps. Other organizations documented include two which merged with NPIC, the Mountain Supply Ditch Company and the Box Elder Ditch and Reservoir Company, as well as groups in which NPIC participated, such as the Cache la Poudre Water Users Association, the Northern Colorado Water Conservancy District, and the Four States Irrigation Council. Beyond irrigation, water management, and engineering, other subjects covered in the collection include land planning, oil and gas extraction, and environmental and community issues in the Cache la Poudre Basin.
NPIC worked with records management consultants to organize files in the 1980s, but any order imposed at that time was not necessarily carried forward. Some categories originally defined were retained, others were merged.

The Records of the North Poudre Irrigation Company was donated to the Water Resources Archive by the company in August 2015. A small accession was added in October 2016 (2016068). A box of files primarily related to Halligan Dam originally given to the City of Fort Collins was donated in March 2017 (2017029).
Materials left with the donor include any items still actively used, documents dated 2010 or after, and any so damaged by water or mold that they were unrecoverable.
Some documents in this collection have been digitized and are available through the Colorado State University Libraries website. In the electronic version of this document, direct links appear in context.
Because the NPIC system is a conglomerate of several older systems, many reservoirs have more than one name or have been renamed. Often, reservoirs have both a name and a number; in some instances a reservoir has a number from both Mountain Supply Ditch Company and NPIC. NPIC's main ditch, the North Poudre Canal, is usually referred to as the Main Canal. Below is a list giving structure number, name, previous/other name, location, and notes:

Processing was completed in February 2017. Materials were rehoused in acid-free boxes and folders. Some materials were cleaned for mold; one extremely moldy map was photographed and returned to the donor. Rubber bands, binder clips, paperclips, and rusty fasteners were removed, as were duplicates beyond two copies. Other materials not retained include tax documents, payroll information, rehabilitation project invoices, folders of insurance information, cancelled and unused checks, files on office equipment, photocopies of published sources, materials from organizations not directly related to NPIC, and a videotape reel of dam and/or outlet pipe inspections. Maps were flattened and housed in flat files or rolled onto tubes; some were encapsulated in mylar. One large map was cleaned and restored by a conservator. In the inventory below, number signs were replaced with the abbreviation "No." See the Appendix for a list of reservoir names and locations. The mold cleaning was completed in December 2017, and those materials were incorporated the same month. The 2016 and 2017 accessions were also incorporated in December 2017 as Box 58 and Box 57, respectively.
