Flumes were water filled wooden troughs that brought wood and lumber down from the mountains to feed the Comstock Lodes insatiable need for lumber and fuel. The mountains from Gardnerville to Reno and around Lake Tahoe were clear-cut for the mines and the flumes played a fascinating role in that exciting time.
I found a magazine article from 1896 written by a man who worked on a flume west of Carson City in 1870. The article, “Down A Mountain Flume” is here.
The mountains west of Washoe Valley had several mountain sawmills and flumes between 1863 and 1880.
