Opal Springs, Well # 1, Well # 2, and Well # 3 supply the domestic water for Deschutes Valley Water District (approximately 4000 services). The artesian spring is located 5 miles southwest of Culver at the bottom of the 850 foot deep Crooked River Canyon, less than 150 feet from the river. The artesian wells are located at the east side of the canyon about 300-600 feet south of Opal Springs. Currently, there is no filtration or treatment of Opal Springs or the wells of any kind (nor is any needed).
