. LAND OWNERSHIP The land in the project service area consists mostly of farms and ranches, with settled family farm home sites dating back several generations. All of the agricultural land serviced by the Company is privately owned. Patterns of land ownership have changed considerably since the 1880s, when many small shareholders had 5 or 8 acres and a pattern of small subsistence farms prevailed. Today many farmers have 100 acres or more, mostly devoted to one or two crops. WATER RIGHTS Within the District's approximately 86,000 acres of land capable of irrigation, many water users, including the Sanford Canal Company, are just north of the Colorado - New Mexico border in the area of The Confluence, where the Main Stem and the North Branch of the Conejos converge with the San Antonio River. Irrigators in and below The Confluence hold the last line of defense for the Colorado Department of Water Resources (DWR), which administers the Rio Grande Compact. However, in this critically important reach of the Conejos, where century old structures were built for wetter times, irrigators are facing increasingly high maintenance costs and are too often unable to get their water when in priority. This project strengthens the water rights of irrigators and protects the assets of stockholders throughout the Conejos River system. Platoro Reservoir is located on the mainstem of the Conejos River and serves a large part of the irrigated lands within the District. The Conejos rises at the Continental Divide in the San Juan Mountains and flows through Platoro Reservoir, continuing through Conejos County until it reaches the Rio Grande, 2 miles north of the settlement of Los Sauces. The Conejos River has an annual average flow of 200,000 acre feet. Nearly 40% of Colorado's Rio Grande Compact obligation is met by the Conejos River system, a tributary to the upper Rio Grande. The Rio Grande Compact requires an average of 45% of the Conejos' upper index, including transportation losses in getting the flow to Los Sauces and to the Conejos' lower gauge. There are 42 ditch companies on the main and north channels of the Conejos. Water stored in Platoro Reservoir (Project water) is allocated to lands within the District based on acreage. The Sanford Canal diverts from the Conejos River. The maximum cumulative decreed direct flow rate should be the minimum design capacity of any structure that is located upstream of the service area of the canal. That design criterion is essential to avoid any indication of intent to abandon any part of any water right. Beyond the protection of direct flow rights, further design capacity considerations include possible additional flows from reservoir deliveries upslope tailwater, precipitation runoff, and delivery 10 Prepared by the Conejos Water Conservancy District, P.O.
