The pre- <br />Taylor and pre-Aspinall data was generated by <br />removing the influence of operation of Taylor <br />Park Reservoir and the Aspinall Unit to <br />represent what flows would have been without <br />these developments. The post-Aspinall data <br />shows how the Aspinall Unit has been <br />operated--to capture and store high spring <br />runoff flows for release throughout the year. <br />This has resulted in higher flows in most <br />months of the year, but high spring runoff <br /> <br />flows in late April, May, June, and early July <br />were lessened. <br /> <br />The proposed contract will consider <br />delivering water stored in Blue Mesa <br />Reservoir to the Monument to more closely <br />follow the pre-Aspinall and pre-Taylor Park <br />seasonal distribution of t10ws (the natural <br />hydrology). This would mean that higher <br />t10ws would be released in late April through <br />early July, with lower t10ws released in the <br />win teL <br /> <br />6 <br />
