Marston Lake

What secrets does Marston Lake hold beneath its shimmering surface? Marston Lake sits serenely in Denver, Colorado. It’s more than just a picturesque body of water. It’s a vital reservoir completed in 1902, a key part of Denver’s water story. Marston Lake isn’t just a passive recipient of water. It actively contributes to the city’s lifeblood, sending water to the Marston treatment plant. From there, the treated water flows to homes across Denver. The South Platte River is Marston Lake’s main source. This river, in turn, receives water from the Colorado Western Slope, diverted through the Roberts Tunnel. This ingenious system ensures a steady supply for the reservoir and the city it serves. Marston Lake has witnessed Denver’s history unfold, from its humble beginnings to its bustling present. The lake has also experienced its share of extreme weather. The hottest day on record at Marston Lake was a scorching 104°F in July 1998. On the other end of the spectrum, the coldest temperature plummeted to a frigid -19°F on December 31, 2014. Imagine the lake freezing over in such extreme cold, a stark contrast to the shimmering summer surface. Today, Marston Lake stands as a testament to human ingenuity and nature’s resilience. It’s a vital resource, a historical landmark, and a beautiful reminder of the delicate balance between city and nature.
