Bay area Surf

Wondering if any one had thoughts or experiance to the bay area surf fishing, in regards to how much water is pumping out of our coastal rivers and streams currently and how it affects the distribution(or redistribution) of the perch and bait. Wondering if the fish and bait would migrate further away from the river mouths due to low salinity. or if it even makes a difference because the flows are pushing so hard the fresh water is further off shore.
I dont know. Late, cant sleep. Just wondering
Thanks

So...
The perch were biting on the SMC Coast on Sat. Low tide was about 6:30 at about 830-9 the the fish came alive. Stuck and lost a handful. About a 2hr window of rain wind and sun. It was awsome good fish all but 1 13" + largest went 4 15". Stayed N. Of any large streams. Water down coast was dirty. But lots of. Structure where i's was at
Simple fly that was broke caught all the fish (trailer to some flash).
T 12 was the ticket. Water falls off the bluffs, creeks pumping rain dumping! It was great!
Hope to see you out there!
