I've played with the math a few times and to make it more reasonalbe to calculate, made some pretty big assumptions. I'd say the winter lake level results in a surface area of about 25,000 acres vs the 40,000 at full pool. iirc, we have about 3000 sq miles in our river basin. Takes a significantly larger amount of rainfall to get those last few feet. How much rainfall is necessary to fill is relative. How much is used in power generation? Flash flood type rains fill quickly, but do not sustain the lake level during the summer season. That is evident in the past few years summer levels. Filled well, but dropped off quit a bit as the summer progressed. We are a long, long way from refilling our water tables.
Being in the tourism industry, the lake level plays a huge role to me. I've had numerous questions about the level so far this year. Not belittling the gulf disaster last year, but they were off only 35% and talking about how hard that was. When the exceptional drought hit us a few years ago, we got up to 60-8o% off from mid July onward.
