'''Marston Lake''' is a reservoir in [Denver, Colorado](/source/Denver). It is owned by [Denver Water](/source/Denver_Water) and was completed in 1902.<ref>Denver Water. [http://www.denverwater.org/AboutUs/History/historicaltimeline/ Historical timeline]. Viewed: 2016-07-13.</ref> The reservoir sends water to the Marston treatment plant, and from there the water is distributed to Denver residents.

The reservoir receives water from the [South Platte River](/source/South_Platte_River). The river receives water from the [Colorado Western Slope](/source/Colorado_Western_Slope) through a transmountain diversion via the [Roberts Tunnel](/source/Roberts_Tunnel).
