We rode down the path specifically to find this and was disappointed to find that it's just some dirty algae windows.

Don't bother. This is not an attraction.

This has been around for a long time. Located behind the Harvest House Hotel (formerly affiliated with Hilton and Clarion, and now with Millennium for the past decade+) along Boulder Creek, an excavation with a walkway in it puts you at water level in the creek. You can attempt to look through mid-sized round windows in the wall separating you from the creek. But the windows and the creek water are usually quite difficult to see through, with sediment and water bubbles usually hiding anything that does not randomly wander within a few inches of the windows.

Difficult to find, and once we got there it looked as if the glass hadn't been cleaned in quite some time -- there are several big, round windows looking into the creek, but only about the top four inches were clean enough to be able to view the creek. The rest were covered with scum. Not really much to see.

A hard place to find as there are no signs indicating its location. Actually is a creek that is part of a walking/bike trail systems and tennis courts in the area. Runs through an apartment system for the college. There were several what I assuming college aged people swimming in the creek including the area where you can see underwater so they were watching each other. No chance at all to see any kind of fish or anything. Was a nice area, but a total waste of time.
