I was on the Morgan falls overlook park side a few weeks ago. No luck which I had no room to cast and water was swiftAh... well yeah if you are in the area and have the time. I just wouldn't be driving down here on the weekends if I was up there.
A kayak makes all the difference no doubt. Wish I'd have gotten one years before I did.
As others have said, the dam is probably the easiest/most productive. There are trails on the west bank you can walk to several different wade-able spots and many fish right there at the dam/boat launch. You can also wade at Settle's Bridge.
