Lake Manly arithmetic...

[David_Bricker]

Also remember that even though there is 1.9 inches of rain a year, there is some, albeit not a lot usually, water that flows into the basin from the Amargosa River.  I've seen the river high enough, at the bottom of West Side rd, that crossing it in my lifted 4wd Jeep would have been ill advised.

So, it might be even longer than 91 years.
