Anyone know what this is and what it does or what it owns? Vegaswikian (talk) 19:46, 13 January 2008 (UTC)

Source of the Lake
It's mentioned at least three times - once on the article for the Las Vegas Wash and twice on this article - that the Las Vegas Wash is channeled beneath the lake to reach Lake Mead. So then how was Lake Las Vegas filled if not by the Wash? Or was it that it was originally filled by the Wash before the Wash was taken under the lake? This all needs to be clarified. --Criticalthinker (talk) 07:04, 22 April 2020 (UTC)


 * The lake was initially filled using an extension of a tap on the WWII BMI pipeline. I revised the text to be accurate. LLV Engr (talk) 22:12, 26 July 2023 (UTC)
 * Wait, with Lake Mead being lower, how did that work, and what's BMI? I'm not sure I understand, and the cited sources doesn't actually mention this. Also, a question about the hydrology in general. The 1991 aerial seems to show a culvert/flume built directly through the dam. Is it a case that despite the Wash going under the lake bed, there is actually a controlled outlet from the lake, too? I imagine this must be for an extraordinary case in which the lake becomes too high? I'd like to see a hydrology section or subsection added to describe the direction of water.

 * Yes lake mead is lower than LLV (Lake Las Vegas). The BMI (Basic Magnesium Inc) system was built to provide water to the BMI complex for WWII (World War two).  There is a pump at the lake mead end that pumps water out of lake mead to Henderson, the location of the BMI complex.  Henderson is higher in elevation so water from a tap on the BMI pipeline provided water to LLV for fill. As a matter of fact, the BMI pipe pressure had to be reduced to prevent erosion at the outlet into LLV.
 * The LVW (Las Vegas Wash) flows under LLV through two 84" dia pipes that go through the LLV Dam. LLV also has a valved outlet into the pipe through the dam.  As far as I know it has never been used except during testing after installation.  Excessive water in LLV flows out through three overflow structures.
