Theodore Roosevelt Lake Reservoir and Dam

IMG_9617

It is an amazing sight. The lake/reservoir is formed by Theodore Roosevelt Dam built on the Salt River in 1911. We remember that river from yesterday’s post on the Salt River Canyon.  It is located 130 km from Phoenix. Roosevelt Lake is a popular recreation destination.

Saguaro Fact #2:  A saguaro may contain two tons of water. Ribs or folds give them structural rigidity, provide  more surface area for photosynthesis, and allow them to expand and contract depending on how full they are of water. During droughts they can dehydrate up to 80 percent and still survive.  Roots may dry, too, and develop a hard cover in order to keep moisture from escaping. Then, when rain does come, the plant will send out new roots-rain roots-within hours and harvest all the water it can. A thirsty saguaro can rehydrate in a few days.

Built in 1911, the Roosevelt Dam is the largest masonry dam in the world. Modified in 1995, 77 feet was added to provide increased water storage and flood control for Roosevelt Lake.
