CDSS Administrative Calls tool. <br /> DWR accounting staff can provide guidance on incorporating this <br /> information within an accounting spreadsheet. <br /> o The Name of the calling water right <br /> o "In" or "Out"-of-priority either for all structures covered by the <br /> accounting or for each structure in its own column. Use a formula to <br /> compare the Priority Admin Number of the calling structure to the <br /> Priority Admin Number of the structure(s) in the accounting. <br /> d. Depletion Ft Obligation tab <br /> Used to (1) convert well pumping (and groundwater pond evaporation) to lagged <br /> depletions impacting the stream and (2) show lagged depletions that are <br /> out-of-priority, and (3) include any additional water obligations of the plan for <br /> augmentation. <br /> i. Calculate lagged depletions - Although well pumping and modeling may use a <br /> monthly step function to determine the depletions from pumping, the monthly <br /> result may, if requested by the Division Office or required by decree, then be <br /> divided by the number of days in the month in order to calculate a daily impact <br /> for daily water administration. <br /> 1. Well Pumping (or groundwater pond evaporation) - Reference back to the <br /> Input tab for the acre-feet of water pumped or evaporated. <br /> 2. Consumption factor (%) - If the decree or approval describes that a <br /> percentage of the water pumped is consumed and only the consumed amount <br /> is replaced. <br /> 3. Acre-feet consumed - Multiply the acre-feet pumped by the consumption <br /> factor. <br /> 4. Delay Factors - show factors that convert pumping in one month to depletions <br /> in future months. These may be percentages per month, that total 100 <br /> percent over an extended period of time. <br /> 5. Depletions - a formula that combines previous months and present month <br /> pumping with the delay factors to determine depletions impacting the stream <br /> this month and in future months. <br /> ii. Out-of-priority depletions are combined into one column for each reach <br /> considering the administrative call information included on the Input tab. <br /> iii. Return flow obligations (if applicable): Replacement water sources changed from <br /> a historical irrigation use usually have a return flow obligation that must also be <br /> tracked in accounting. Return flow obligations are similar to depletions because <br /> they must be replaced in time, place, and amount. Depending on decree <br /> language and preference, return flow obligations may be included under the <br /> replacement tab in section 4.e. below. For each replacement source with return <br /> flow obligations, include the following: <br /> - the basis and volume of the return flow obligation, <br />
