o The Name of the calling water right <br /> o "In" or "Out"-of-priority either for all structures covered by the accounting or for <br /> each structure in its own column. Use a formula to compare the Priority Admin <br /> Number of the calling structure to the Priority Admin Number of the structure(s) in <br /> the accounting. <br /> d. Depletion Ft Obligation tab <br /> Used to (1) convert well pumping (and groundwater pond evaporation) to lagged depletions <br /> impacting the stream and (2) show lagged depletions that are out-of-priority, and (3) include any <br /> additional water obligations of the plan for augmentation. <br /> i. Calculate lagged depletions -Although well pumping and modeling may use a monthly step <br /> function to determine the depletions from pumping, the monthly result may, if requested by <br /> the Division Office or required by decree, then be divided by the number of days in the month <br /> in order to calculate a daily impact for daily water administration. <br /> 1. Well Pumping (or groundwater pond evaporation) - Reference back to the Input tab for the <br /> acre-feet of water pumped or evaporated. <br /> 2. Consumption factor (%) - If the decree or approval describes that a percentage of the water <br /> pumped is consumed and only the consumed amount is replaced. <br /> 3. Acre-feet consumed - Multiply the acre-feet pumped by the consumption factor. <br /> 4. Delay Factors - show factors that convert pumping in one month to depletions in future <br /> months. These may be percentages per month, that total 100 percent over an extended <br /> period of time. <br /> 5. Depletions - a formula that combines previous months and present month pumping with the <br /> delay factors to determine depletions impacting the stream this month and in future <br /> months. <br /> ii. Out-of-priority depletions are combined into one column for each reach considering the <br /> administrative call information included on the Input tab. <br /> iii. Return flow obligations (if applicable): Replacement water sources changed from a historical <br /> irrigation use usually have a return flow obligation that must also be tracked in accounting. <br /> Return flow obligations are similar to depletions because they must be replaced in time, place, <br /> and amount. Depending on decree language and preference, return flow obligations may be <br /> included under the replacement tab in section 4.e. below. For each replacement source with <br /> return flow obligations, include the following: <br /> - the basis and volume of the return flow obligation, <br /> - the location of the return flow obligation, <br /> - replacement of the return flow obligation. <br /> e. Replacement tab <br /> List each structure providing replacement water, transit loss information, and volumes released: <br /> i. Structure providing replacement water: name of reservoir, ditch, well, leased or other <br /> replacement water, its WDID, and the water court decree allowing its use for augmentation or <br /> replacement. For instructions on accounting for replacement using recharge accretions, refer <br /> to specific recharge guidance. <br /> ii. Replacement water travel distance (miles) <br /> the distance from the point of release to the location of the out-of-priority depletion where <br /> replacement is owed <br /> iii. Transit loss percent per mile (%) <br /> Questions can be submitted to Ask DWR by visiting the DWR homepage at: dwr.colorado.2ov/ Page 7/15 <br />
