Delamar, Nevada, nicknamed The Widowmaker, is a ghost town in central eastern Nevada, USA along the east side of the Delamar Valley. During its heyday, primarily between 1895 and 1900, it produced $13.5 million in gold. In 1889, prospectors John Ferguson and Joseph Sharp discovered gold around Monkeywrench Wash. A mining camp was then born west of the Monkeywrench Mine. It was called Ferguson. In April 1894, Captain Joseph Raphael De Lamar bought most of the important mines in the area and renamed the Ferguson camp as Delamar. In the same year, a newspaper called the Delamar Lode began publication and a post office was opened. Soon, the new settlement boasted more than 1,500 residents, a hospital, an opera house, churches, a school, several businesses and saloons. Most buildings were made of native rock. By 1896, the Delamar mill was handling up to 260 tons of ore daily. Water for the camp was pumped from a well in Meadow Valley Wash, some twelve miles away. Supplies and materials traveled even further, by mule team over mountainous terrain from the railroad head at Milford, Utah, which was 150 miles from Delamar. Silicosis The gold in the Delamar mines was embedded in quartzite which when crushed created a fine dust. Miners breathing the dust often developed silicosis and the town became known as a "widow-maker." Many ruins now stand semi-intact in the Delamar ghost town region. Foundations can easily be seen from adjacent hills. There are two graveyards, which have been vandalized. The area is honeycombed with mines and mineshafts, but in recent years the main shaft has been blasted closed. Wild horses roam the area. The nearby dry lake is known to pilots as Texas Lake because its outline resembles the state of Texas.

The "Mole" Jarva Tunnel Borer pokes its nose out of the tunnel through mountain as work on the Las Vegas River Mountains Project progresses. The first stage of construction was completed between 1968-1971, and is comprised of a main aqueduct, a 3.78 mile tunnel through the River Mountains, eight pumping plants, and 31.4 miles of pipeline. This stage has a peaking capacity of 26.7 million cubic feet of potable water per day. The second stage enlarged the first stage system by expanding some of the existing facilities. New features included five pumping plants, the second barrel to the main aqueduct, and about 30 miles of pipeline and laterals with surge tanks, regulating tanks, and other delivery facilities. In conjunction with this stage, the State of Nevada enlarged and modified the Alfred Merritt Smith water treatment facilities to accommodate additional water supplies. The River Mountains Tunnel was constructed to full capacity in the first stage, and the Saddle Island intake facilities were oversized to accommodate both stages. The aqueduct system has a peaking capability of 53.4 million cubic feet of water per day. The River Mountains Tunnel was constructed during the first stage to accommodate second stage expansion. It is 3.78 miles long and was excavated through the River Mountains, which lie between Las Vegas Valley and Lake Mead. The concrete-lined tunnel has an inside diameter of 121.5 inches, and a maximum capacity of 608 cfs. The SNWA also constructed a larger tunnel, parallel to the River Mountains Tunnel for further expansion. The River Mountains Tunnel is used to convey raw water from Lake Mead to the River Mountains Water Treatment Facility that SNWA constructed near Henderson, NV. The River Mountains Facility, which began delivering treated water in October 2002, treats up to 300 million gallons of water per day, and was designed so it can expand to meet Southern Nevada's needs. In the future, the River Mountains facility will be able to treat up to 600 million gallons of water a day. This facility provides additional reliability and capacity to Southern Nevada's municipal water treatment and distribution capabilities.
