Q: Why is it called Soap Lake?
A: There are several reasons for the name Soap Lake. The mineral laden water has a slick, almost soapy feel to it. It is also very easy to float in the water. Another reason is the white foam that appears along the shore of the lake after a strong wind. This phenomenon is usually observed in the fall and the spring when the air temperature is colder than the water temperature.

Q: What minerals are in the lake?
A: There are up to 23 different minerals in Soap Lake water. The most abundantly occurring are calcium, magnesium, potassium, silicon, and sodium. At various times over the last 90 years, water quality assays have been conducted to test the mineral content of Soap Lake water. Records show that the mineral content of the lake has declined. Compared to the ocean, and other known naturally occurring mineral resources in the world, Soap Lake still has the highest diverse mineral content than any other body of water on the planet. Soap Lake water also contains ichthyol, an oil like substance sold over the counter in Europe to treat infections and abrasions. The icthyol in Soap Lake water most likely comes from the decomposition of tiny brine like red shrimp that flourish in the water from late spring to mid-summer.

Q: Can you drink the water?
A: Many people have over the years, and many still do. The water is strong tasting. A public drinking fountain on Main street, just west of the Inn at Soap Lake has a spigot for both regular and Soap Lake water.

Q: What causes the suds around the lake?
A: No one knows for sure. After a strong wind blows, usually during fall and spring months, the suds, may appear as a band of white froth or clumps of swirling white suds up to a foot high along the shore of the lake.

Q: Where do I find Soap Lake mud?
A: Soap Lake mud can be found in various locations on both the north and south ends of the lake. There are different “grades” of Soap Lake mud. The best is the creamiest, jet black variety that has a strong sulfur odor. There are several locations on the East Beach as well as the cove behind the library where it can be obtained by diving in shallow water. The best way to find out is to ask a local resident or to inquire at the Healing Water Spa on Main Street or the Visitor Center on the west side of highway 17 just past the edge of town.

Q: How was the lake created?
A: Through a sixty million year geologic process punctuated with shifts in the earth's crust resulting in molten lava escaping from fissures, then a period of floods, more earth changes and several more floods. Ultimately, the landscape was covered with basalt rock that has been scarped, carved and channeled by the remarkable power of water. A landscape truly created by fire and water. With layer upon layer of basalt rock in place, it took several hundred thousand more years for water to leach through the basalt and fill a plunge pool left from an ancient waterfall. The waterfall was located on the southernmost end of the river channel created during one of the most violent floods known to have occurred on the North American continent. This part of the channel is now called the Lower Grand Coulee. As the pool and surrounding area filled with water, a deposit of silty clay formed along the bottom creating a sealed container. The water continued to flow into the bowl, retaining an assortment of minerals leached during thousands of years of migrating through the porous basalt.
