Water temperature that once ranged from near freezing to 80 degrees F (27 C) now runs year-round within a few degrees of 46 F (8 C), because water for power generation is drawn from well below the surface of Lake Powell.

Water temperatures for the river typically average 50 degrees year round. During hikes we can see waterfalls and side streams that can be much warmer.
The source of its milky blue watersIn the Little Colorado River, calcium carbonate forms a type of limestone called travertine that creates white, pillowy deposits along the riverbed. Most of the turquoise-blue water in the Little Colorado River comes from springs 10 to 13 miles upstream of the confluence.
Water Temperatures in Grand CanyonWater temperatures in the Colorado River average 50° year round as it flows from the Glen Canyon Dam. Side streams and waterfalls where we occasionally stop for hikes can be much warmer.
No, swimming near the edge of the Grand Canyon is not recommended and is generally not allowed for safety reasons. The Grand Canyon is a massive and steep-sided canyon carved by the Colorado River in Arizona, USA.
The highest temperatures are found at the lowest elevations inside the canyon. Low relative humidity and generally clear skies mean that most of the sun's energy is available for daytime heating. These same conditions lead to rapid heat loss at night.
Water available at these locations has been deemed safe for all human and animal consumption. Potable water at Grand Canyon is treated at multiple locations before being distributed for consumption. Grand Canyon treats all potable water beyond State of Arizona and EPA standards for public consumption.
Colorado River Safe Drinking Water While traveling in the backcountry, river running, or hiking, you will utilize water from the Colorado River, side streams, seeps and springs, or other sources. Any water from these sources has the potential to cause illness if it is not properly and carefully filtered and treated.
Encompassing an estimated 1,218.37 acres (1,904 square miles), the Canyon is capable of holding 1 – 2 quadrillion gallons of water. Really. If you poured all the river water on Earth into the Grand Canyon, it would still only be about half full.
Other red rock formations that contain oxidized iron minerals include the Chugwater Formation in Wyoming, Montana and Colorado and the Redwall Limestone cliff of the Grand Canyon, which was stained red by the iron-oxide minerals leaching out from the layers above it.
The North Rim is also the wettest location, with an average of 25.8” of moisture a year (45.03” in 1978). Lees Ferry is the driest, averaging only 6.1” of yearly precipitation (and only 2.7” in 1955). Deep canyons and rough terrain strongly influence solar heating and air circulation.
As air sinks down into a lower elevation, it gets compressed, compressed air releases heat as energy. This caused the air mass to become even warmer. “This is why you can see temperatures in the 90's at the top of the Grand Canyon but temperatures 20-30 degrees hotter at the bottom of the canyon,” Brink says.
The Colorado River through Grand Canyon averages 300 feet (91 m) across and about 40 feet (12 m) deep. The average flow is between 12,000 and 15,000 cubic feet per second (cfs).
View Grand Canyon SafelyIn areas where there is a railing or fence, do not climb over the barrier. Keep an eye on all of the people in your group, especially small children. Make sure that your travel companions have both feet firmly planted on pavement or developed trails at all times. Know where the edge is.
E.coli bacteria has been detected in the water supply inside the Grand Canyon National Park in Arizona, according to an advisory released by the National Park Service (NPS).
Temperatures vary quite dramatically depending on season and also on altitude. In general, the Inner Grand Canyon is warmer and can you dangerously warm in the summer if not prepared. In contrast, the temperatures on the North Rim and South Rim can be quite cold in winter.
The deepest part of the Grand Canyon is 6,000 feet (1,829 meters). The average depth is 1 mile or 5,280 feet (1,609 meters). At the suspension bridge this canyon is 1,053 feet (321 meters) deep. At Artist Point Overlook the canyon is 1,200 feet (366 meters) deep.
