reregulation volume and attempts to release the full volume, up to J-2 capacity (specified in cell B40), when being cycled. This general rule can be over-ridden as described in the notes for column 25. In this • example, approximately 1,000 ac-ft of space was targeted for hydrocycling operations. The hydrocycling volume which remains in Johnson Lake at that days' end (col 18) is equal to the change in Johnson hydrocycling volume for the day (cfs inflow - cfs outflow = col 17 - co120, & converted to ac-ft), plus the previous days' hydrocycling volume in Johnson Lake (col 18, previous day). The example currently shows a two day cycling pattern for the level of non-EA inflow (i.e., re-reg 1 day, release the next) and column 19 is used to specify the frequency of cycling. This column could also be adjusted to reflect a 3-day cycling pattern (e.g., reregulation for 2 days and release the next) if system inflows are anticipated to be lower. Column 19 is also used to match up releases from the EA volume being re-regulated/released (using a similar flag in column 24) during the pulse flow release. The worksheet currently does not simulate a situation where hydrocycling inflow is being primarily re- regulated into Johnson Lake while a smaller volume is simultaneously flowing out the J-2 return. Although the formula in column 18 (hydrocycling reregulation volume) accounts for that potential situation, the formula in column 20, discussed next, foYCes the condition of re-regulating all hydrocycling inflow into Johnson Lake and setting the hydrocycling J-2 outflow to zero if the reregulation flag=0. This general rule can be over-ridden as described in the notes for column 25. Column 20: If the reregulation flag (col 19) is zero, then that days' J-2 hydrocycling outflow is zero cfs as water is being re-regulated into Johnson Lake. Otherwise, the J-2 cfs outflow is computed as the volume available for cycling (col 18, previous day), converted to cfs, plus the cfs inflow available (col 17). This potential cfs outflow is limited to the J-2 capacity (cell B40). Note that the cfs hydrocycling J-2 outflow in column 20 is a 24-hour avera-ze of the hydrocycding release, the sub-daily cfs rate will typicadly is vary between 0, 450, 1,050 and higher cfs rates, depending on the re-regulated volume available and system inflow available for hydrocycling. JOHNSON LAKE - EA OPERATIONS Column 21: Johnson Lake EA inflow is the CNPPID EA diversion, lagged 2-days, multiplied by a percentage conveyance factor for that reach which is specified in cell B41 (currently, 0.75). The first two days of column 21 in the example are zero (because there are no previous two days to compute on). Columns 22-25: are similar in concept to the hydrocycling reregulation columns, but for the EA water. Column 24 uses a similar flag to specify whether EA water is re-regulated in Johnson Lake or released out of the J-2 Return. The worksheet does not enforce a maximum value for the EA reregulation volume (col 22) or the total volume re-regulated shown zn column 23 (EA reregulation plus Hydrocycling reregulation volume, col 18 + col 22). In this example, approximately 3,000 ac-ft of space was targeted for EA reregulation, and 1,000 ac-ft for hydrocycling operations, or a total of 4,000 ac-ft for both. Column 22: The EA volume which remains in Johnson Lake at that days' end is equal to the change in EA volume for the day (EA cfs inflow - EA cfs outflow = co121 - co125, & converted to ac-ft), plus the previous days' EA volume in Johnson Lake (co122, previous day). Column 23 is the sum of the hydrocycling and EA reregulation volumes (col 18 + co122) in Johnson Lake. Column 24 is used to time the EA release out of Johnson Lake, along with Hydrocycling water (col 19), to • match up with flow travelling down the mainstem Platte River (co129) and arriving at Overton (keep an Water Year 2008 EA AOP 40 October 15, 2007
