Each of the participating ditches have repayment <br />contracts with the District whereby annual payments are made based upon available water <br />during the year. <br /> <br />The Colorado Division of Parks and Outdoor Recreation operates Trinidad State <br />Park at the reservoir site which provides a wide array of recreational opportunities. <br /> <br />Operations During the 1999 Irrigation Season: <br /> <br />Operations of the Trinidad Project during the 1999 irrigation season began with <br />predictions of runoff as late as Mayof only 23% of normal. Late snOVvfall and higher than <br />average rainfall during the growing season provided the opportunity to provide a full <br />irrigation supply to all of the project ditches, except for the Model Land and Irrigation <br />Company, and actually resulted in the filling of the reservoir to the bottom of the flood pool <br />during the period when John Martin Reservoir was spilling. <br /> <br />The Model land and Irrigation Company was unable to divert during most of the <br />irrigation season due to the rendering of it's canal inoperable as a result of severe rains <br />and was granted permission by the Secretary of the Interior to irrigate past the traditional <br />end of season date of October 15 in order to salvage some economic benefit. The Model <br />Company irrigated up to and including October 19, 1999. <br /> <br />The Project ditches diverted 612 acre-feet of stock water during the calendar year <br />1999. A composite summary of diversions by each project ditch is appended to this report. <br /> <br />The Corps of Engineers conducted a sedimentation survey during the latter part of <br />the irrigation season which indicated that 1,227 acre-feet of silt had been deposited in the <br />reservoir since the last sediment survey was conducted. <br /> <br />A composite hydrograph of reservoir storage and releases is appended to this <br />report. <br /> <br />Future Activities: <br /> <br />The District has embarked on two projects designed to enhance the monitoring, <br />allocation, and reporting functions related to the opera~ion of the Trinidad Project: <br /> <br />2 <br />
