Ms. Jennifer Lind~ahl Page 3 Latimer Pit, M-74-069 and Mariana Butte Pit M-88-033 March 14, 2008 acre-feet. Replacements during May through October will be made by diverting the Barnes Ditch water, measuring it, rind then returning it to the Big Thompson River. Adequate flow measuring devices, satisfactory 1:o the water commissioner, must be installed for the administration of this replacement water from the Barnes Ditch. Replacement for ~jepletions during the months of April and October will be met by releases of C- BT water leased from Loveland. For the approval period of this plan, Loveland Ready Mix leased 8.57 acre-feet of C-BT Project water. A copy of the approved lease from Loveland was provided to this office on February 14, 2008 and is attached to this letter. The use of C-BT water as a replacement source requires Lovelland Ready Mix to comply with the Interim Rule issued by the Northern Colorado Water Conservancy District ("District") in May 2005 regarding the use of C-BT Project water in substitute water supply plans. A copy of the District's approval letter for the use of the C-BT water in this plan was provide~~ to this office on March 12, 2008 and is attached to this letter. Per the Interim Rule, the net yield of the leased C-BT water is 50% of the net C-BT water delivered to the appropriate river reach for depletion replacement. In accordance with the District's Interim Rule, the 9.00 acre- feet of leased C-BT ~niater committed to this plan will be used to provide 4.29 acre-feet of replacement credit. The C-BT watE~r is approved for use in this substitute water supply plan however; it cannot be used as a replacement source in a permanent plan for augmentation for this site.
