One and a half days to standing water

It’s research to be sure, but there’s no starched white lab coats, it’s ducking and weaving behind tree trunks and skidding precariously down inclines, all to the continued amusement of the Oft-Crapping Pooch …

My current theory of rainfall, ground saturation, and the rise of the Big Muddy, is that my local soil can assimilate only one and one half days of sustained rain before the creek is the sole beneficiary.

After 36 hours of rain the Little Stinking became mud brown and rose a couple of feet. Three days later it was still up but clear …

After another 24 hours of heavy downpour, the creek was unrecognizable, as it rose about five feet and went from fifty feet across, to nearly 100 yards wide.

Wide and Muddy

Naturally, compressing all that water through the notch at Huff’s Corner narrows it some, which increases both depth and velocity, ensuring a heavy scour.

Narrower but deeper and much fasterAs each new season requires me to retrace my steps to assess all the scour-induced topography changes, I had mixed emotions about the new tree trunk in my favorite hole – whose corresponding root ball now dominates the shallows above. Most of these woody “gifts” claim many dozens of my finely crafted flies, typically when I’m down to the last of whatever is working that day.

I’d feel better if I could claim those flies during the dry spells, but that rarely happens. Each winter sends the log into the brush above the creek and away from view, or launches the beast into the Sacramento, along with all the lawnmowers and decayed shopping carts.

My only hope is the predictive services offered are a bit more accurate than your weatherman, as guessing on storms and their payload is a science based on an awful lot of hypothetical …

… mostly involving how much water the ground can absorb, versus how much will wind up as actual runoff.

beaver_scrub Travelwriter sent me this link just after I’d returned his dog from a hike through the watershed, which featured the obligatory back scrub in fresh beaver deposit, so I’m not altogether sure whether I’m doing you a favor or not. (You may want to rely on your own observations until you can confirm the site is accurate.)

In short, it’s a NOAA map of California showing what storms are calculated to dump and the resultant effect on watersheds. Additional tabs feature what the storm actually dumps and once past, allows you to compare the pre- and post- conditions for accuracy.

Just remember its tea leaves and tarot cards, a predictive engine for rainfall and runoff.

While flood prediction is not terribly exciting to fishermen, those of you chasing steelhead and salmon can get insight into what a fresh storm has in store, and how badly flows might be altered, and may save you a fishless fishing trip or two …

Yesterday’s big winter blast rolled through the valley leaving green and chocolate in its wake.

One little turn of the spigot and I’ve got six feet of muddy water roaring through the channel, suggesting outside of a dry spell, fishing will be slim for the next couple of months.
