Hey guys, it's Olivia Allen Price, and this is Bay Curious.

I want to tell you about one of my favorite spots in the Bay Area.

It's just a few miles from where I live in San Mateo. The Crystal Springs

reservoirs are these two perfectly clear blue lakes that are surrounded by miles and miles

of rolling green hills.

They stretch as far as the eye can see.

If you've driven through the peninsula on 280,

you've seen what I'm talking about, off to the west.

Now, I love this spot for the way the fog rolls over the hills in the afternoons and just how blue the water is next to the green hills.

It all looks so pristine, untouched, natural, but it's entirely man-made.

Today on Bay Curious, we're getting to your questions about the Crystal Springs Reservoirs. How are they made? Who made them? And why can't we hike more of that area? Stick around.

Support for Bay curious is brought to you by Sierra Nevada Brewing Company, still family owned, operated, and argued over.

Explore their brews wherever fine beverages are sold, and taste how trailblazing runs in the family.

When Jackie Nunez moved to San Mateo from Santa Barbara, she couldn't help but notice the Crystal

Springs Reservoirs.

I moved here quite recently, maybe two years ago, so I'm really curious about just the history of this land and getting to know my surroundings.

Jackie studied environmental science in college, so maybe it's no wonder this was her question for us.

What's the story behind Crystal Springs?

There's not much information about it online

other than that it's a man-made reservoir.
