San Anselmo Creek (Cascade Canyon, Fairfax) Water Level

This is a water level sensor on the San Anselmo Creek in the 200 block of Cascade Drive. This is the only creek level monitor that I know of in the Cascade Canyon.

Why is this Interesting?
In past years, I have noticed that when the creek behind my house gets to about 44 inches, there will likely be a high-water alert in downtown San Anselmo 30-40 minutes later (approximately 2.6 miles to downtown San Anselmo). The Cascade Canyon represents approximately 26% of the watershed basin west (upstream) of downtown San Anselmo.

Caveats
The monitoring equipment is not professional grade equipment. It is homemade using electronic components purchased on the Internet. Although I have attempted to guard the electronics from the elements, they certainly are susceptible to moisture, temperature changes, wind, gnawing rats, wild coyotes and likely a myriad other things I have failed to consider.

I really have no idea what I am doing. I am not a hydrologist, nor a civil engineer, nor do I have any specific training in storm water management. However, I do live on a creek, and I have an interest in electronics and computer programming – I'm a "geek on a creek".

This system may not always be available. This system relies on an array of wireless, Ethernet, Comcast cable and a multitude of devices to get a signal from my creek to your computer. Any of these could malfunction at any time, especially Comcast.

Bottom line: Don’t base your decision to either load your kids, dogs, cats or parakeets and evacuate, or to "tough it out" on the information on this page
