The second and third pipes were laid by the late Captain J.B.Overton, who was Superintendent of the Company for over thirty-two years.

Captain Overton also extended the flume lines, constructed the tunnel through the mountain ridge, built the Marlette Lake dam and made many other improvements and extensions.
On leaving Marlette Lake through an opening at the lower portion of the dam the water is conducted five miles in a covered flume and thence through a tunnel four thousand feet long through the summit of the dividing ridge or rim of the Tahoe basin to its easterly side.
From this point it is again conducted through covered flumes, together with water from Hobart Creek and other streams, to the intake of the pipes across Washoe Valley.

These pipes are three in number, two twelve inch and one ten inch.
