Title
CRDSS Task 1.15-17 Colorado River Basin Representative Irrigation Return Flow Patterns
Description
The purpose of this task was to develop return flow patterns for both the monthly and daily CRDSS planning models using geologic parameters representative of actual locations of irrigated acreage in each of the five CRDSS basins and a methodology that is acceptable and can be reproduced.

As noted in the Daily Yampa Memo, the State's model develops monthly patterns based <br />on 365 days/12 months, therefore the sum of daily returns shown in Table 6 is based on 30.4 <br />days in each month. <br />Table 6 <br />Monthly Return Flow Pattern and Daily Return Flow Pattern Comparison <br />- Lands Further from Stream <br /> <br />Month Monthly Return <br />Flow Pattern % Daily Return Pattern based on <br />30 da s of rechar e <br />1 60.4 59.9 <br />2 14.5 15.3 <br />3 7.2 7.1 <br />4 5.0 5.0 <br />5 3.7 3.7 <br />6 2.7 2.7 <br />7 2.0 2.0 <br />8 1.5 1.5 <br />9 1.1 1.1 <br />10 0.8 0.8 <br />11 0.6 0.6 <br />12 0.4 0.3 <br />Total 100.0 100.0 <br />Page 11 of 12 <br />
