Water Level in Lake Mead Drops to Record Low


Extended droughts has resulted in the lowest water level at Lake Mead since the largest reservoir in the U.S. was filled in the 1930s when Hoover Dam was built. Lake Mead declined to 1,074 feet above sea level on May 19, 2016, below a previous record set on June 25, 2015.

The U.S. Bureau of Reclamation (BOR) recorded a high water line of 1,229.0 feet but considers the lake as “operationally full” at 1,219.6 feet elevation. The minimum water level to generate power at Hoover Dam is defined at 1,050 feet, below which the lake becomes an “inactive pool.” When water level goes down below 895 feet, the lowest water outlet at Hoover Dam, the lake is a “dead pool” as nothing would flow downstream from the Hoover Dam.

Lake Mead's water level reached a record high of 1225 feet in the summer of 1983, and has been in steady declines since 2000.

Lake Mead supplies water to 20 million people in California, Nevada, and Arizona. With the prospect of water levels dropping further, water managers in the above three states are under pressure to work out a plan to temporarily cut back water withdrawal from the lake.

Postcard US-3482775 to New Jersey shows Lake Mead with 'bathtub rings' on its shores and islands, which indicate the devastating effects of water level declines.

Postcard CZ-806944 from Czech Republic shows Lipno, a village in the South Bohemian Region of the Czech Republic. It is located along the Vltava River next to the Lipno Dam. The dam was built on the Vltava River between 1952 and 1959 as a flood control measure. With an area of 46.5 km2 or 4650 ha and a capacity of 306 million m3, it is the largest reservoir in the Czech Republic. Lipno Hydro Power Plant has two turbines with a combined capacity of 128 megawatts.

Orlík nad Vltavou

Postcard CZ-600263 from Czech shows Orlík nad Vltavou, a village in the South Bohemian Region of the Czech Republic. According to Wikipedia, the village was formerly called Staré Sedlo, named after the castle. In Czech, "nad Vltavou" means "upon the river Vltava" and both the castle and the village are located on the left river bank, on the shores of the Orlik reservoir as a result of the construction of Orlík Dam. The Orlík Castle, standing right next to the water, is surrounded by a huge park and a game preserve. It belongs to the House of Schwarzenberg, a Bohemian and Franconian aristocratic family, but it is open to the public on most summer days.

Chung-cheng Lake in Meinong, Taiwan


This postcard from a private swap shows the Chung-cheng Lake (中正湖) in Meinong District, Kaohsiung, Taiwan, Republic of China (ROC). A man-made lake originally built in 1748 known as Jhongjun Pi (中圳埤), it was renovated into a reservoir between 1916 and 1920 during the Japanese occupation. With an area of 21 hectares or 52 acres, the lake had a capacity to furnish water for irrigation of over 130 hectares or 321 acres of farmland. It was also used for fish farming. After World War II, the lake was renamed to Chung-cheng Lake in 1956, after Chiang Kai-shek (蔣介石: October 31, 1887 – April 5, 1975), also known as Chiang Chung-cheng (蔣中正) who was the leader of the Republic of China between 1928 and 1975. A pavilion was also built in the lake in honor of Chiang. However, there have been petitions to change the name of the lake to Meinong Lake (美濃湖) since 1996, in protest of Chiang's role in the 228 Massacre. On a side note, many statues of former president Chiang Kai-shek have been vandalized across the island around the 68th anniversary of the 228 Incident on Saturday, February 28, 2015.

While the lake capacity for water supply has been diminishing due to sediment built-up since the 1957 Meinong flood, it becomes part of the largest wetland ecosystem in the area that hosts a large number of migratory birds during the winter months from October to March next year. More than 60 bird species have been spotted around the lake. A wooden boardwalk around the lake was completed last November to accommodate nature lovers.

Kiev Water Museum


Postcard UA-1093827 from Ukraine shows the Water Museum in Kiev, Ukraine. Kiev has several museums dedicated to the city's infrastructure and services, such as Kiev Fire Service Museum, Kiev Pharmacy Museum, Kiev Recycling Museum, Kiev Sewer Museum, the National Museum of Health Care in Kiev, and Kiev Water Museum,

The Water sits in the park "Kreschaty" on a hill with its water towers and reservoirs, as part of the natural and cultural center. The site was once the Royal Garden, founded in 1743 by order of the Empress Elizabeth. The old water towers and reservoirs were renovated in 2003, and the first Ukrainian Water Information Center was introduced to tell the story of Kiev's water usage from the river to the tap and back to the river again. It has a giant toilet, a bubble making station, and a Koi aquarium that are not only educational but also entertaining.

As we witness the water levels at the Lake Mead dropping to a new record low in Las Vegas, copping with water shortage has becoming a struggle world wide.

Also 101 years ago today, the temperature at Death Valley, California, hit 134°F or 57°C on July 10, 1913, the highest recorded in the United States.

Dniester Canyon, Ukraine


Postcard UA-951602 from Ukraine shows Dniester Canyon, a 250-km or 155-mile river segment of the Dniester River from the mouth of Zolota Lypa River to the mouth of Zbruch River. According to Wikipedia, Dniester River is the second largest and the most ecologically clean river in Ukraine.

Similar to the Colorado River below the Glen Canyon Dam in the United States, Dniester Canyon is partly flooded by reservoir waters. While the water depth can reach up to 50 meters, the canyon valley has its depth varied from 80 to 200 m or from 260 to 650 ft. Its original and unique geological, botanical, archaeological, and hydrological nature earned its reputation as one of seven natural wonders in Ukraine. Dniester Canyon was recognized the National Nature Park on February 3, 2010.
