Walk-on
And remember, the first 50 is a lot easier than the last 50
Because this first 50 is just filling the very bottom of the V of all those canyons and that last 50 is going to be way more square miles of water surface to fill per foot

Lake Mead water level up 5+ feet since July. But overall prediction is that it

Really? I thought (and maybe I'm wrong) that Powell was going to suffer in order to fill Mead.

Powell is closer to dead pool than Mead

Powell and Mead are both sitting at about 150 feet above dead pool. Powell is a slightly smaller reservoir so based on

I think the idea is that you can always send water downhill but can't send it...

What is the prediction for Powell this year?

Lake Powell watershed is at 142% of normal. Predictions are 45 feet +/-

And that’s with holding some water back from mead? Hopefully we get a few years

If next year were like this year, we would be normal again in the West

I wouldn't count on all time records happening consecutively- though in the mid 80s

4 Mega winters (like this year) in a row would probably do it-

Man, 50 feet of water in a reservoir like Powell is a LOT of water.

It's almost unfathomable when you start trying to quantify it. Especially with how "little" rain and snow the west gets

If everything is already full, it all ends up in Mead

But the point is Powell won't fill until year 3. Mead wouldn't fill until year 4.

Surface elevation isnt a great way to quantify improvement, especially at Powell

Colorado has had a really good last few weeks. All of their basins that feed into the Colorado system are 127-155% of

The water levels are very close to 2017- that year Powell rose 50 feet and Mead rose 30 feet.

I'm sure the predictions I'm reading haven't been updated. Looks like they were

The key is to get multiple years of this, hopefully.

Like 4 straight years of this would get us back to full pool at both reservoirs.

Rain expected next week M-W in southern Utah at least.

Back in 2005 when St George had floods for a week. It rose the water level at

I thought Lake Mead was the more efficient storage location?

Interesting. Mead has a much larger surface area and probably loses more to

Lake Mead has a surface area of 247 sq. mi. Lake Powell’s is 266. Mead may have a greater storage capacity, however.

Yeah, the massive evap losses are the best argument on the side of those who argue that Powell and Mead should never
