California Delta:

DELTA, Sacramento side — The catch-and-release season opened on Wednesday, October 1, and the diamondbacks were chomping outside of the Pittsburg Marina. Striped bass fishing remains ‘up and down’ with by far the best action from the Benicia/Martinez Bridge to Collinsville. Live bait has been effective on both sides of Broad Slough, but it is a matter of finding the schools. The best is yet to come as there are still numbers of striped bass in San Francisco Bay. Largemouth bass fishing is best in the north Delta around Liberty Island with flipping in the shallows. As the waters continue to cool, the northern strain largemouth bass are transitioning onto structure.

DELTA, San Joaquin side — Striped bass fishing is best around the Antioch Bridge as the linesides continue to hang out in the coolest water. The central Delta has been ‘hit or miss’ and there are numbers of undersized stripers in the system. Once again, catching numbers of largemouth bass hasn’t been a problem, but finding anything of size is a challenge as despite 69 of the west’s best bass anglers fishing the Bass Angler Magazine’s three-day Delta Super 60 showdown, the largest fish was 8.98 pounds.
