Been watching these videos. Vegas is in serious trouble. Even when the lake is completely full the average depth of the lake is only 400' deep, but the average depth of the lake right now is only around 200'. The lake is currently dropping at a rate of 8 inches a day, and later in the summer it is expected to increase to about 1.5' a day. Even at 8 inches a day, this would be a drop of 240 ' in a year, which means Vegas could be out of water in a year.
We are not the only ones that will be affected though. The water existing Lake Mead is used to irrigate crops in Southern California, and a lot of the electrical power for Los Angeles comes from the Hoover Dam. Right now we are in an inactive pool status, with power production down to around 30%. Just over another 100 foot drop and we will be in a dead pool status, where no power can be produced from the dam.

The lake is currently dropping at a rate of 8 inches a day . . . You posted the same baloney last week. Lake Mead is down five and a half inches since the first of July. That’s seven days.

Have no idea where you are getting your nonsense from, but you really need to fact check. Even that guy at the lake whose boat engine stopped and he pulled up to the beach, his boat was high and dry in the week he tried to get a mechanic out there to check the engine. And the park rangers are saying 1 to 1.5 drop in water level per day.

You really think this guys boat got that far out of the water within a couple of weeks after parking it at the beach with a 5 inch water drop per week.
And this was when the temperatures were cooler.

vegasjames I told you last week the water level dropped four and a half feet in June, an average of an inch and three-quarters/day. In the last year, 7/1/21 – 7/1/22, it’s down twenty-six feet . . . and you’re trying to tell us it’s gonna drop another two hundred and forty feet–OR MORE–by next summer? [chuckle] That bathtub ring didn’t show up overnight, it took decades. Now go get a “ruler” and tell me what the water level is today, do it again next week, and we’ll take it from there. Wouldn’t surprise me if some rocket scientist out there can’t differentiate water level from receding shoreline.

Wouldn’t surprise me if some rocket scientist out there can’t differentiate water level from receding shoreline. I see you evaded answering how this guy's boat got so high and dry at least 50 feet from where he parked the boat in a couple of weeks. Maybe you think an earthquake suddenly pushed up the land under his boat in that time? If not. them the water had to drop drastically, more than a few inches in those couple of weeks.
And yes, the bathtub ring took several decades to become that visible. So what? Apparently you do not realize various facts involved such as the fact that when the dam was built it backed up the water in to sloped canyons, not straight walled canyons. Why is this important? Because for every square acre of surface , the actual amount of acre feet of water varies depending on the part of the lake. The shallower sloped areas drop a lot faster, and as the lake drops it will continue to drop faster as the same acre of water is released due to the sloping.
Furthermore, as I just pointed out there is a certain amount of release below the dam that goes to California, then eventually to Mexico if it is lucky. California has a right to a certain amount of water under the agreement between the states. The problem is that we keep releasing that water down to California, but Hoover Dam is not the only dam on the river. For water to reach Lake Mead, the water has to be released from the Glen Canyon Dam that forms Lake Powell. Problem is that they RECENTLY started to hold water back from release from Lake Powell to help maintain its levels at the expense of Lake Mead. This is therefore, leading to a more rapid drop in the lake levels at Lake Mead since there is a decrease in water coming in to Lake Mead recently. Even you should be able to understand that concept.
"A normal operating level for Lake Mead and Hoover dam is defined as 1,221 feet so people looking at just the math may not think this is such a big deal but what they often don’t realize is the lake is constructed as a “V” bottom meaning the lower it gets, the faster the water level drops. Experts are now saying the lake water level appears to be dropping about 8 inches a day which will now begin to accelerate due to the profile shape of the lake. "
Wow, a little simple research verifies what I have been explaining to people for a while.
Your low projections may reflect just the evaporation losses from Lake Mead, but is not taking in to consideration the outflow from Lake Mead, or the shape of Lake Mead or the recently reduced outflow from Lake Powell.

In an effort to settle the argument, I googled around to find a correct answer and I could not find one solid answer that everyone could agree with. Suffice to say - the level is dropping. Does it matter how fast? The result is the same terrible conclusion. It's just a matter of when.

jasoninsd Here’s a good pastime when you aren’t out rockhounding! markb I watched that to the end. It amazes me the trash (bottles!) that people will throw down wells, latrines, and over cliff edges! They certainly had no respect for the environment - out of sight, out of mind! Thank you for posting that!
