12/8/2019 State.co.us Executive Branch Mail - Pueblo West - CS-U/Super Ditch Fallowing-Leasing Pilot Project <br />https://mail.google.com/mail/u/0?ik=1f3905cd06&view=pt&search=all&permthid=thread-f%3A1650782868965932987%7Cmsg-f%3A16507828689659…2/4 <br /> <br />4. There shall be no renewal of this temporary lease/fallowing project after the ten year term. Any <br />continuation of this operation must first obtain Water Court approval under the resume-notice <br />procedure. <br /> <br />5. Lagged return flows must be replaced upstream of the location of the lagged return flow at all <br />times. <br /> <br />6. Super Ditch must lease enough space in Pueblo Reservoir to assure that the requirements of <br />the 10CW4 Decree are met, prior to exchanging water into Pueblo Reservoir. <br /> <br />7. The stepped exchange provisions in 10CW4 should be applied to all exchanges under the Pilot <br />Project regardless under which decree, or which administrative approval, the exchange is <br />operated. <br /> <br />8. Delivery of return flow water that is needed to replicate historical conditions must be made on a <br />daily basis; only excess return flow water can be stored for later release. <br /> <br />9. In order to receive HCU credit, dry-up must be confirmed and monitored by (a) establishing <br />monitoring wells or piezometers on all dry-up parcels except those approved by the Division <br />Engineer as not being susceptible to high groundwater table; (b) notifying all parties to this <br />proceeding and those in Case 10CW4 as to the location (by legal description and map) of all dry <br />up parcels no later than 1 March for the coming year; and (c) posting those parcels sufficiently to <br />allow “windshield” or “drive by” confirmation of the absence of plant growth attributable to high <br />ground water or irrigation. <br /> <br />10. The effect of alternating a parcel between fallowed and irrigated require further study to <br />determine whether such a practice would increase the actual consumptive use on those parcels for <br />years when they are being irrigated. If during the 10 year project, they switched back and forth <br />every year from irrigation to fallow, in the five years when the parcel was being irrigated it would <br />consume more water than during the historical average year, and so if Super Ditch got the average <br />credit for the five years of fallow, the total for the 10 years would be too high. The solution would <br />be to reduce the credit for years of fallow so that the ten year average would be protected. <br /> <br />If Craig Lis has any questions about the above, he is free to discuss with Pueblo West’s engineer <br />Alan J. Leak, P.E. without the need for any further approval by me. <br /> <br />Thanks! <br /> <br />Bob Krassa
