Another area within Lake Mead NRA rich with springs is Black Canyon downstream of Hoover Dam. Here you can find springs of both the thermal and non-thermal variety, with water temperatures ranging from about 55 to 136 degrees Fahrenheit. Some of the springs are pools and others are seeps. Seeps are wet rock faces that at times are up to 100 feet long. Many of these seeps are covered with a mixture of travertine and algae-type vegetation that can range in brilliant shades of green and orange, depending upon the temperature of the water.

Nevada Hot Spring is a popular visitor destination that can be accessed by boat on the Nevada side of Hoover Dam. Located within Goldstrike Canyon, this spring (actually series of springs) produces a number of picturesque pools of varying temperatures, as well as lovely waterfalls that can provide a welcome sight to intrepid hikers.

Another popular spring to visit in Black Canyon is Arizona Hot Spring, which is located about 4 miles south of Hoover Dam. This spring’s existence has been known for some time, and it was noted on a map in the "Report upon the Colorado River of the west, explored in 1857 and 1858" by Lieut. Joseph C. Ives of the U.S. Army Corps of Topographical Engineers. Arizona Hot Spring can be accessed via a scenic hiking trail located off of Highway 93 on the Arizona side of the Colorado River, and it produces fairly constant 111 degree Fahrenheit water that drops through several small pools.
