Workers at Lake Mead on Wednesday did something not seen in many years. They actually raised a boat launch ramp. The ramp at Hemenway Harbor was briefly closed as crews adjusted the pipe mat and dock for account for rising water level.

Bureau of Reclamation officials said Monday that the lake has been rising because of “recent storm events and runoff into the tributaries that enter Lake Mead.”

Other factors include reduced releases from Hoover Dam and a “decrease in downstream demand,” according to the bureau. Officials did not provide additional information on the decreased demand.
