While the Chicago River's color is (supposedly) safely achieved, the Daqubang in eastern China has been observed to take on bright hues of red, orange, and green as a result of industrial pollution.

Newport Beach, California
MatadorU faculty member Scott Sporleder has endured many wintry mornings to capture intimate photos of water like this.
Devil's Bath, Waiotapu, New Zealand
Located in the North Island's Waiotapu geothermal area, the Devil's Bath gets its color from mineral runoff from the adjacent Champagne Pool (appearing further down this list).
Wave action under the Red Sea
Photo tip from the photographer: "You don't have to dive deep to capture beautiful scenes. Here, I'm 3-5 meters underwater, and I waited about 15 minutes to capture the effects of a large wave hitting the reef that I eventually liked."
Lac Rose, Senegal
Algae in the waters of this lake northeast of Dakar produce a red pigment -- apparently it's most pronounced during the dry season (December-April).

Krka National Park is another protected area in Croatia where water features are the central draw. Skradinski Buk is the name of this grouping of lakes and falls.
Red tide at Half Moon Bay, California
The algal blooms that cause red tide events can occur naturally, but they are also the result of coastal pollution from agricultural runoff and other sources.
Jigokudani Monkey Park, Nagano, Japan
The Japanese macaques, or snow monkeys, that live in this park spend winter days warming themselves in the natural hot springs.
Lake Michigan wave, Chicago
A storm in late October of 2012 kicked up a wall of water at Diversey Harbor Park. This cyclist seemed unfazed.

At Geneva, the muddy mountain waters of the Arve come together with the larger Rhone River at this dramatic confluence.
Thor's Well, Cape Perpetua, Oregon
One of many scenic features on this stretch of Oregon coast, Thor's Well is a depression in the rock that sucks in ocean water and, under the right tidal conditions, shoots it back out like a fountain.
Salar de Uyuni, Bolivia
The world's largest salt flat is a desert of white in the dry season but takes on an inches-deep standing pool of water after heavy rains, creating on of the freakiest-looking landscapes on Earth.

MatadorU faculty member Scott Sporleder shares this image from Palawan, the Philippines' most remote province and home to many beaches with super clear water.
Seven Ghosts, Sumatra, Indonesia
At certain times of year, at certain places in the world, a rising tide will travel upriver or into a small bay, creating wave action. Sumatra's Seven Ghosts is one of the most legendary of such tidal bores, particularly in the surf community.

Puu Kukui, Maui, Hawaii
Streams of water cascade down the sheer vegetated slopes of Puu Kukui in the West Maui Mountains.
La Jolla Cove, San Diego, California
Frequent algal blooms along this part of the Southern California coast can produce some intense bioluminescence in the waves.
Monterey Bay, California
An example of a "high surf advisory" situation off the coast of California.
Keith Malloy reaches out to an unridden Tahitian barrel as he enjoys the waves from a new perspective.
Víti Crater, Iceland
The crater of the volcano Askja in eastern Iceland is mostly filled by Öskjuvatn lake; the adjacent and much smaller Viti Crater is also filled with water, which often differs in color from that of Öskjuvatn.
Hartlepool Headland, England
Waves pound against this breakwater in northeastern England.
Peyto Lake, Banff
Another glacier-fed lake in Banff National Park. Here you can clearly see the "rock flour" that enters the lake via glacial runoff, lightening the overall hue several shades.
