How can you know what type of fish is legal to catch tomorrow or Saturday or Sunday I am driving from Salem or to cascade locks

Call the department of fish and wildlife

Look it up online for current info

There's signs posted right at Marine Park and around the Columbia Market. I'm Living in Cascade Locks. Also Oregon fish and game has all the information online.

Google Oregon fishing report and the ODFW website click on it,then click on report. Columbia River should be obvious option to click. Then scroll down until you see the are you want. Or call one of the ODFW locations and talk to someone who knows. Sauvie Island usually answer the phone or The Dalles.
