Thankfully we've been lucky in the avoiding-the-tornado's department, but the sky never seems to quit falling!
Was supposed to be good weather today, but that stopped at about 3pm. Trip to lake put off till tomorrow...

Haven't heard much about potential flooding yet...definitely not a drought year!

How many of those rivers feed into the Colorado? That would be REALL GOOD!

SoCal has yet another storm going through this weekend. Snow down to 5000 feet elevation. Mammoth Mountain in the eastern Sierra broke the old snow-in-May record with 29 inches of snow.
Looks like it might surpass that this weekend. Maybe a few more days will be a good indication of some normal weather, and boat launching.

Lake surface temperature is only 55*. But, the lake is still running over the spillway.


Have a great day of boating

Here is a slightly different view of the same basic data
[img]http://www.usbr.gov/UC_SnowMap/[/img]
Everything Between the Dark Seperating lines flows into the Colorado. The Sevier, Provo, weber and Bear drainages go to Utah Lake and the Great Salt lake, while the south Eastern drainages go into the Rio Grande
The high Snow Water Equivalent (SWE) in the southern areas really doesn't mean a whole lot other than lack of drought, since the typical SWE is really small, so 150% of really small number is still pretty meager.
This Graph shows the amount of snowpack vs the "Average" in the Lake Powell watershed over the past 10 years. That water will eventually flow through Powell into Mead and down the Colorado into SoCal.

has been almost exactly what the water managers would order. Warm Up to melt the lower elevations, then cooling to slow the flow. Warmup to melt the mid elevations, with more cooling.
then more warming for the upper elevation snowpack. this has reduced the peak flows, while spreading the run off over time, which will keep the upper lakes fuller longer, and hopefully the precip we've been getting will keep us from using reservoir water to water our lawns.

Thanks, Justy.
Looks like the Colorado will be flowing more than the last 6 years. Has anybody projected how much the Colorado River lakes will rise? Wouldn't it be great if the lakes got back 1/2 of what they have lost? Of course, more is better.


Have a great day of boating

Jack, check out Lake Powell water database for lots and lots of really good links to water flows and projections. for all the lakes in the Colorado river basin.
Powell and Mead will not fill up this year, and probably never in the future, but we are looking better than last year.
On the Waynes Words website (link at top bar of that page) there is a high level contest which given the theory of the knowledge of the masses would put Powell topping out at 3622.13, or about 40 feet higher than it is right now.
Powell is probably about 20% into it's yearly rise, while Mead is on it's yearly decline (Typically peaks in mid March and bottoms out in late August).
I think the upper lakes of the Colorado will fill up, and they'll hang on to as much water as they can for as long as possible. Later this year they'll make the decision to release more from Powell than the minimum required to help put more into Mead, but we need a good 5-7 years of snowpack like this year to get to where we'd all like both those lakes to be.
Flew over Utah Lake yesterday and I think it FR makes it there this weekend to work on the Skipperliner he'll take time off later this week to take one of his other boats out to enjoy how much water they have. Utah lake doesn't help the Colorado basin at all, but it is a good indicator of how much snow we got this year.

Thanks Justy. I hoped the Colorado Basin would be projected to do better.
