Mike, I agree that Valley has become much wider and shallow. Some of my favorite bend pools that used to have some depth and hold some larger fish... these nice holes are vanishing quickly... and at an accelerated rate over the past 3 years or so.
No doubt. Valley Creek changes with every major rainfall event because of the direct runoff resulting from the development along its banks. Couple that with unstable banks and the result is siltation and channelization.
The stream bed of Valley is like the shifting sands and changes with each major storm event. There seems to be one every year or two that is greater than 4000 cfs in the stream that normally flows from 20-40 cfs (that's 100 to 200 times the normal flow)...see below.
The entire stream changes with each event. Many of the big fish holding areas have been wiped out.
