So what is the do not exceed water level to maintain a larger Powell, basically is there a water surface elevation point that if exceeded would actually result in lake Powell going to a lower level at the end of the year with more water going to Mead? Is the water going to Mead a percentage of total of what Powell gets each year or a stepped fixed amount, if fixed then it sounds like Powell would stay bigger by keeping just below that point to have a higher elevation at end of annual cycle. Is this a fair game or would Powell dump excess water to Mead early (if less than additional requirement amount) to stay below that level. On the flip side would the powers manipulate the levels by holding water to barely hit that level resulting in a larger release if fixed. Is there a priority lake? Does Mead split the loses to seeping and evaporation at Powell or do they get a full wet share with Powell absorbing all natural losses. Regardless, more water the better and good for Mead to be raising too.
