Parker Dam was built between 1934 and 1938 and spans the Colorado River between Arizona and California 155 miles downstream from Hoover Dam. Parker Dam is the deepest dam in the world with 73 percent of its structural height of 320 feet below the original riverbed. Two-hundred and thirty-five feet of the Colorado riverbed was excavated before concrete was placed for the dam's foundation. Only about 85 feet of the dam is visible; the dam's superstructure rises another 62 feet above the roadway across the top of the dam. Parker Dam provides reservoir storage for water to be pumped into the Colorado River and Central Arizona Project Aqueducts. Lake Havasu, the reservoir behind Parker Dam, is about 45 miles long and can store nearly 211 billion gallons of water.
The goverment complex for the Colorado River Indian Tribes is located just a few miles off Arizona Highway 95 near Parker. They have government offices and a nice library there. They often have displays about the history of the tribes and hold special events there. The address is for the CRIT Tourism Bureau.
The Parker Chamber of Commerce is also the Visitors Center. This is a great place to pick up literature on attractions and activities in the town and the surrounding area. The lady working there when I visited was helpful and friendly.
The La Paz County Historical Museum is housed in a building temporarily donated by a local family, and has several displays depicting the history of the area including the World War 2 Japanese internment camp located nearby in Poston and the history of Indians in the area, early mining and ranching, and the settlement of the town. Like many small town museums, money is tight and hours are flexible depending on the availability of volunteers. The museum is generally open only by appointment in the summer and 11AM to 3 PM Thursday through Saturday in the winter. Admission is free; but donations are accepted and needed.
One thing that makes the Colorado River Indian Tribes Museum interesting is that it represents the FOUR different tribes that lived in the area; the: Navajo; Hopi; Mohave; and Chemehauvi. The museum has the world's largest collection of Chemehauvi Baskets and a number of well-presented displays about the history and traditions of the tribes. There is also a gift shop with a number of original tribal arts and crafts for sale. There is no photography allowed inside the museum. Hours are 8 AM to 5 PM Monday through Friday. Admission is free; but donations are accepted.
Next to the Chamber of Commerce/Visitors Center is Main Street Park, a small park partly dedicated to the coming of the railroad.
Parker has a decent little historic district with a few buildings of historical and/or architectural interest. I especially liked the church.
