Seven Oaks Reservoir

Seven Oaks Dam is a 550-foot (170 m) high earth and rock fill embankment dam across the Santa Ana River in the San Bernardino Mountains, about 4 miles (6.4 km) northeast of Redlands in San Bernardino County, southern California. It impounds Seven Oaks Reservoir in the San Bernardino National Forest. The dam was proposed in response to major floods in the mid–20th century, and was constructed between 1993 and 2000. Seven Oaks is a dry dam that serves mainly for flood protection to Orange, Riverside and San Bernardino Counties, although it also used to impound water for groundwater recharge. One of the largest embankment dams in the United States, the dam was built under contract from the U.S. Army Corps of Engineers (USACE) by Odebrecht Corporation of California, a subsidiary of the Brazilian firm Contructora Norberto Odebrecht,. The dam is now owned and operated by local flood control districts.

Mill Creek is a 17.8-mile-long (28.6 km) stream, originating in the San Bernardino Mountains, in San Bernardino County, California. It is a major tributary of the Santa Ana River. Their confluence occurs just downstream of the upper Santa Ana Canyon mouth. Part of the upper creek flows through San Bernardino National Forest, with the headwaters (High Creek and Mill Creek Jumpoff), being in the San Gorgonio Wilderness. Mill Creek is in much better condition than the lower portions of the Santa Ana watershed, as its drainage area is less urbanized. However, the creek has three hydroelectric plants owned by Southern California Edison. The first commercial power plant in the United States using three-phase alternating current was the 250 kilowatt Mill Creek No. 1 Hydroelectric Plant, near Redlands, California, in 1893 designed by Almarian Decker.The streambed is completely dewatered in some places. Also, a levee system was built by the United States Army Corps of Engineers after a severe flood, which degraded the riparian habitat. In addition, the poor conditions downstream interfere with fish migration to the creek.

The Mill Creek Zanja, also known as the Zankey, is a historic irrigation canal, or zanja, in Redlands, California. The Serrano people dug the canal in 1819 to provide water from Mill Creek for their farms east of the city. The zanja also provided water for the San Bernardino de Sena Estancia mission outpost, which was built near the canal to access its water. The canal's water became a highly desirable resource in the area; it fueled a local agricultural boom and was the subject of several legal disputes over water rights in the 1800s. The City of Redlands covered the western half of the zanja in the 1920s.The zanja was designated a California Historical Landmark in 1932, named a Historic Civil Engineering Landmark in 1972 and placed on the National Register of Historic Places in 1977. The canal now carries drainage water and storm runoff out of the city; it is the oldest irrigation canal in California which is still in use and the oldest civil engineering project in Southern California. The city, along with several other local groups, is building a trail and greenway alongside the canal.
