Mr. Heintz & Ms. Wynne Duckworth SWSP January 27, 2014 Page 6 of 7 ( "LCP ") and into the Smith & Emmons ditch. The Smith & Emmons ditch must measure the dewatering water diverted directly back to the river. Any dewatering water placed into LCP cannot be used for irrigation or any other purpose by Lighthouse Cove Development or others, and must be allowed to accrete to the stream. The provision in the SWSP allowing LCP to be used as a recharge pond may not be continued in SWSP renewals should it be determined by the water commissioner or division engineer that water within LCP is being diverted for use or accounting is not adequate to show that recharge of dewatering is occurring. 10. All diversions shall be measured in a manner acceptable to the Division Engineer. The Applicant shall install and maintain such measuring devices as required by the Division Engineer for operation of this SWSP. In addition, the applicant shall maintain daily records of all diversions, replacements, and the amount of water used for each particular purpose. The applicant shall provide a report of these records to the division engineer (Divl Accounting Ca�state.co.us) and the water commissioner (Bob Carlson at Bob. Carlson(a-),state.co.us) on a monthly basis. The accounting must be submitted within 30 calendar days of the end of the month for which the accounting is being made and conform to the Administration Protocol "Augmentation Plan Accounting, Division One — South Platte River" (attached). 11. The name, address, and phone number of a contact person who will be responsible for the operation and accounting of this plan must be provided on the accounting forms to the Division Engineer and Water Commissioner. 12. Conveyance loss for delivery of augmentation water is subject to assessment and modification as determined by the division engineer or water commissioner. 13. The approval of this substitute water supply plan does not relieve the Applicant and /or the landowner of the requirement to obtain a Water Court decree approving a permanent plan for augmentation or mitigation to ensure the permanent replacement of all depletions, including long -term evaporation losses and lagged depletions after gravel mining operations have ceased. If reclamation of the mine site will produce a permanent water surface exposing groundwater to evaporation, an application for a plan for augmentation must be filed with the Division 1 Water Court prior to the completion of mining, to include, but not be limited to, long -term evaporation losses and lagged depletions. If a lined pond results after reclamation, replacement of lagged depletions from mining and dewatering shall continue until there is no longer an effect on stream flow. 14. The Division Engineer, or his designated representative, will administer all such water transported in the South Platte River or its tributaries under this SWSP, including water for replacement of depletions, past intervening headgates to ensure that such water is not intercepted or otherwise diminished in quantity by diversion, use or other interference by intervening water rights and to assure that such water remains available and suitable for Applicant's uses under this SWSP, except when any intervening headgate is diverting the entire flow of ( "sweeping ") the river. In the event that delivery past headgates which sweep the river requires the installation of a bypass structure or the use of an existing bypass structure by agreement with a third -party, Applicant is responsible for either installing a new bypass structure with a continuous recording measuring device(s) as approved by the Water Commissioner or securing an agreement with a third -party to use an existing bypass structure and providing such information and agreement to the Division Engineer.
