Land subsidence is not a new topic of discussion in California. It has been a part of California’s agricultural history ever since farmers introduced large-scale wells to pump groundwater from the Central Valley’s aquifers. In a very interesting photo, USGS Scientist Dr. Joseph F. Poland stood next to a telephone pole near Mendota, CA in 1977 to show the effects of land subsidence on the valley floor. As you can see in the linked picture, he put signs on the telephone pole noting where the land would have been in 1925, 1955, and 1977. Dr. Poland’s analysis determined that the valley floor in that area fell approximately 8.93 meters (over 29 feet!) between 1925 and 1977 when he took that picture. Unfortunately, after a century of pumping in the Central Valley, little has yet changed to make the process more sustainable. Continue reading

Eminent Domain and the BDCP
Rick’s Café Californian
California’s water world is abuzz with the revelation that the BDCP involves acquisition of land parcels for the project’s diversion facilities and 30-mile twin tunnels, either by acquisition or by Eminent Domain. As Rick Blaine (aka Humphrey Bogart) stated in Casablanca, “I’m shocked. Shocked to find that gambling is going on in here.” Continue reading
Southern Nevada’s Water Supply through the Drought – Making the Most of Limited Water Supplies
In the drought-parched Western United States, it is hard to find a silver lining in the economic and social costs that the long-term drought has caused. But at Lake Mead on the Colorado River, people are trying to make the most of the limited water supplies and take advantage of the unique sights that the low water levels have revealed. In late July, CBS News reported that the exceptionally low lake levels have revealed interesting historical attractions that up until the drought, were essentially unreachable. The receding shoreline revealed the foundations of Saint Thomas, a pioneer town that Mormon settlers founded in 1865. Until the US government purchased the land in the 1930s, the town was inhabited and included a school, homes, a general store and ice cream parlor. In the 1990s, 100 feet or so of water would have covered the ruins of Saint Thomas. Now, visitors can hike for about a mile across the desert to reach the foundations of the former town.

California’s Urban Water Management Plans: Balancing Future Growth and Water Supplies
Earlier this year, The New York Times wrote an article entitled “California Drought Tests History of Endless Growth”, which garnered significant media attention. The article prominently featured a picture of a large house with a green lawn in the middle of the desert, with a large suburban subdivision in the background. In fact, the picture was taken in Rancho Mirage, a city in the Coachella Valley near Palm Springs. Further research determined that the subdivision is a gated community named “Versailles”, and the houses are built near the famed Sunnylands compound, which has hosted among others, eight US Presidents, Queen Elizabeth and one of Frank Sinatra’s weddings. Sunnylands is a 200-acre estate with a 9-hole golf course, 11 man-made lakes and a pool. Continue reading
