Napa & Bay Striper + Lake Sonoma Fly Fishing Report

 Capt. Patrick MacKenzie Reports on May 17th, 2025

Napa River

Clarity: Off 

Temp: 64-66F

Fishing has been inconsistent with the changing water clarity, but there is a lot of bait around, especially in middle section which bodes well for the summer fishery in the wildlife refuge! Schools of smaller stripers have started to show up after the smolt drops in Mare Island / Carquinez.

SF Bay

Clarity: 0-4ft 

Temp: 58-64F

Fishing has picked up in SP & Central Bay, we are starting to get all the fish coming back from Delta & rivers! South Bay has consistent water clarity and striper activity. Now is the time to get a day on the calendar and hope for good weather!! 

Lake Sonoma 

Clarity: 2-4ft 

Temp: 65-69f

Lake Sonoma has early smallmouth / crappie window still, lots of recreation boats starting to show up. Topwater / FF still both viable options until Mid-June!
