<br />N Sources: All values, except for the "1993 Basin Outflow," are from, "Water for Tomorrow, Colorado State Water Plan,
<br />Phase I - Appraisal Report" dated February, 1974. The "1993 Basin Outflow" is the long term average from USGS Water Resource Data for Colorado -1993.
<br />This comparison indicates no significant change in the long term average basin outflow. See "1.3 Background" section of the report for further discussion.
