There are many places to swim in the bright blue waters of Lake Mead and Lake Mohave. Be aware that there are no lifeguards in the park. Always wear a life jacket. Most fatalities at Lake Mead National Recreation Area could have been avoided if the person in the water was wearing a life jacket.
If we're lucky, billions in federal cash will spur enough water conservation, over and above what the current rules require, to limp the lake through 2026.
But while Lake Mead has filled up slightly since its low point of July 2022, the Bureau of Reclamation anticipates that the water levels will start to decline again come spring. A Bureau of Reclamation study published in January predicted that Lake Mead could reach a new all-time low in 2023.
As crazy as it sounds, engineers say the idea is technically feasible. It would involve building a system of dams and pipelines to move the water uphill across multiple states over the Continental Divide. Gravity would then work in our favor to drop the water down to the Colorado River watershed.
Lake Mead retains just over one-fourth of the water that it was originally filled with, according to reports from July of 2022. The main contributors to Lake Mead's decreased water levels, besides population growth leading to depletion, include drought and climate change.
Can I eat the fish from lakes Mead and Mohave? Yes. Fish from lakes Mead and Mohave have been sampled for heavy metal and mercury concentrations since 2002.
While not a persistent, widespread problem, the “Swimmer's Itch” parasite is believed to be present in lakes Mead and Mohave. While found in warm, shallow waters anywhere from only a few weeks to an entire summer, the parasite is not a life-threatening concern, but one that can cause some discomfort.
It would actually take six more years of heavy rainfall in a row to refill the Lake Mead reservoir completely. Time is ticking to solve the problem before future droughts dry up the lake completely. Without irrigation, farmland like this in California and other western states would revert to the desert.
“While the amount of precipitation received in the lower basin and from tributary inflows helps, the greatest source of water for Lake Mead is still snow melt and flows from the upper basin.”
Without Lake Mead, Las Vegas would lose access to 90 percent of its water sources. If Lake Mead were to reach dead pool, it would technically still be able to supply drinking water to Las Vegas. But there will not be enough water for agricultural activities.
Investments to enhance system conservation and improved hydrology have led to significant improvements for Lake Mead this year, the federal government announced Tuesday, after the lake hit historic lows last year and the remains of several bodies were found.
The water elevation in Lake Mead is around 1,040 feet above sea level. At 950 feet, Hoover Dam will be at its lowest point to be able produce power, according to the US Bureau of Reclamation.
