SPDSS Memorandum <br />Final <br />To: Ray Alvarado and Ray Bennett <br />From: LRE, Mary Presecan and Erin Wilson <br />Subject: Task 5 -Key Structure, Larimer and Weld Irrigation Company <br />Date: March 5, 2005 <br />INTRODUCTION <br />One of the Task 5 objectives is to: <br />Develop and document an understanding of the operations of key water use facilities in <br />the basin in order to facilitate consumptive use modeling and to support selected data <br />needs for modeling being done by other contractors. This understanding will be <br />developed through interviews with DWR personnel, operators of large canal and <br />reservoir systems, and representatives of federal facilities. <br />Types of key water use facilities include diversion structures, transmountain diversions, <br />reservoirs, and reservoir systems. <br />Key diversion structures, identified as part of Task 3, include structures representing 85 <br />percent of net decreed rights, structures diverting greater than 1,000 acre-feet per year, and <br />structures of administrative importance. <br />Key transmountain diversions, identified as part of Task 4, include those structures that <br />transport non-native water from another basin into the South Platte River basin. <br />Key reservoirs, identified as part of Task 5, include reservoirs or reservoir systems with <br />greater than 10,000 acre-feet capacity and/or reservoirs that should be included in potential <br />future modeling efforts due to their impact on basin operations. Reservoir systems are <br />defined as a group of reservoirs on the same tributary or filled by the same diversion <br />structure that satisfy a common demand or are operated in a similar fashion. <br />A number of structures in the Larimer and Weld Irrigation <br />Company System have been identified as key structures <br />for the South Platte Decision Support System (SPDSS) <br />consumptive use and surface water modeling efforts. The <br />purpose of this Task 5 memorandum is to document <br />physical, legal, and operational aspects of those key <br />structures identified. <br />Table of Contents Page <br />Introduction 1 <br />System Overview 2 <br />Physical Information 3 <br />Water Rights 14 <br />Operational Information 17 <br />References 20 <br />The information provided in this memorandum was developed from publicly accessible sources. <br />This memorandum has not been reviewed by the Larimer and Weld Irrigation Company. <br />Information in this memorandum is believed to be accurate.
