Onion Creek is a tributary of the Colorado River in central Texas. It starts in Blanco County, flows mostly in Hays County and joins the Colorado in Travis County. It is about 79 miles long. It’s watershed is about 211 square miles and it’s an important geological feature in central Texas.

Onion Creek is one of my favorites spots in the entire county and it’s near our home. I always enjoy visiting it and am always pleased with what I find. Even now, in the middle of a severe drought, I find the creek fascinating. I’d like to share some of my favorite photos, taken in wetter times, but just a few years ago. I keep hoping that it will come back to this.

Here is a shot from 2007. FM150 has two low water crossings on Onion Creek. I pulled off the road at one of them and got this photo.

This one is also taken right off of FM150. There is a weir dam on the creek which causes it to pool behind. I don’t think the water is very deep. I guess it’s about 3 or 4 feet deep. Both of these shots along FM150 are into private property, so I was careful not to trespass.

I took this one while on a Hays County Master Naturalists Volunteer Project at the Onion Creek WQPL. The project involved removing Ashe Junipers (Juniperus ashei) along the banks of the creek.
