to 483' is making it pretty rough on those of us who were told less than a month ago that we had until Feb. 18 to finish dock construction projects! Why couldn't they just wait until the water went down next fall to implement the 3' variance? I would have easily been finished by Feb. 18 but now it's going to be a real hassle. Working in the water on 30-40 degree days is NOT fun!

Referring to the "Water Level Rule" curve, the level would previously have reached 483' around Feb. 28. Under the recently-enacted 3' variance, will the level remain at 483' (assuming it gets there) until Feb. 28 and then follow the curve upward? Seems reasonable to me but who knows?

A question for civil debate and discussion please....truly curious....I have no agenda and like to have a full pool in the summer as much as anyone else....
What amount of water would it take for a three foot rise from 480 to 483? My guess, based on surface area increases as the water rises, is that amount of water would compare to a maybe one to one and a half foot rise as the level approaches full pool. Any engineers (degreed or armchair) out there have an answer or estimate? Or is the increase in surface area as the lake rises actually relatively insignificant compared to the total lake area?

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.

This is NOT scientific and is based on casual observation and my memory...
Over the past several weeks, I've made several trips to Lake Martin to work on a new floating dock. As the water had risen about one and a half feet, it had traversed about 18-20 feet (approx. 6 meters) laterally, at my property. Since the lake has about 1,200 Km. of shoreline, this would result in a surface increase of about 7.2 Sq.Km. Since the area of the lake (Wikipedia) is 178 Sq. Km., that would be about a 4% increase in size, which is not huge, but not insignificant, either. Like I said...a grain of salt. ;-)

Welcome to the Forum, Tiger 62. The lake is being raised early because of the on-going drought. The chances of filling the lake are much better this spring if we can catch the early rains now. This increase has nothing to do with the plans to raise the winter level in the future as part of the relicensing of Martin Dam. We don't know what the future winter level will be yet, but any permanent change will not take effect until at least 2013.

I obviously misinterpreted the intent.
|
Also, you received some bad information because the drought variance for this season was requested over 2 month ago. Fortunately for you, the request was delayed.....this water rise would have happened about a month sooner without some bureaucratic mistakes.
Welcome aboard.

Yeah. I assumed that Alabama Power would know what was going on. 'Taint necessarily so. ;-)
