Kansas also questioned showing bypasses for Ninemile and Highland Ditch Companies when no such bypasses h'ad actually been made. In response to Kansas concerns, additional analyses were done for the 1979-84 review period. Also, studies of the 1925-57 period were made with a 39,000 acre-foot joint-use pool and with no bypass for Ninemile and Highland. Following the April 27, 1988 meeting, both states and the District provided written comments on the second draft report. Copies of the comment letters are included in Appendix V. While extensive comments were again received, this round of comments dealt almost exclusively with the interpretation of the study results, the con- c 1 us ions and the recommendat ions. The methodology, data or other techni ca 1 aspects of the studies contained in the second draft report were not seriously challenged by either state or the District in either the meetings or the written comments. During the Apri 1 27, 1988 meeting, the Bureau agreed to redraft the chapter on the administration of water rights and provide the redraft to the interested parties prior to issuing the final report. The redraft was mailed on October 28, 1988. In preparing the final report, the Bureau of Reclamation has carefully con- s i dered all comments recei ved since the revi ew was i nit i ated.

Basic Data Basic data used in this report were compiled from many sources. Streamflow records of Purgatoire River flow at Madrid, below Trinidad Lake, at Trinidad and at Thatcher Gauges were obtained from U.S. Geological Survey published records or Di vi s i on 2 Engi neer records. These records were judged good except for winter periods. Trinidad Reservoir daily operation data summarized on a monthly basis were obtained from the Corps of Engineers. These data include reservoir water sur- face elevation, storage content, computed evaporation, release, and computed inflow. It was noted at the February 5, 1987 meeting in Denver that the records prior to July 1981 did not reflect the most recent area/capacity tables and were in need of modification. As agreed, the Bureau reconstructed the reservoir storage con- tent, surface area, evaporation and inflow for the October 1979 thru June 1981 period to provide a consistent record based on the current area/capacity table. The reconstructed values are shown in Appendix II. Data after June 1981 were used as reported and considered to be of good quality. Certified copies of Trinidad Reservoir dai ly water accounting and diversion records for ditches under the Di stri ct 's admi ni stration were recei ved from the Colorado State Engineer's Office.
