Seasonal Creeks

12377639_10153144331341786_3674935992491065197_oSeasonal creeks are by definition creeks that only have water during the rainy season. In California, the rainy season can potentially stretch from early Fall into late Spring, although variations in weather patterns can of course add nuance to that schedule. However, for truly seasonal creeks it usually takes a fair bit of rain to form the runoff required to start them up.

So although we’ve had rain just about every week for the last month or so, it was only with the latest storm that we began to see the seasonal creeks on the Overlook Trail and the Montini Preserve begin to run. Specifically, the creek that runs through what I call “Fern Glen” and across the Overlook part of the Rattlesnake Cutoff trail, has begun to run (see pic).

This is good news, as it means that our storage reservoirs will also begin to fill. And having been in a multi-year drought, this is definitely good news. However, runoff by itself isn’t necessarily good. We should trap as much of that as we can into the aquifer, where those who draw from water wells can take advantage of it. To a large degree, this means slowing down the runoff and making it soak into the ground instead of running directly to the bay.

Personally, I think we have a ways to go before we can say that we are doing the best we can at water capture in this valley. Until we figure out how best to harness our seasonal creeks to maximize underground water storage, we perhaps deserve the droughts that we will likely increasingly get.
