Head to the town of Manson and up on the hill past the high school you will encounter Wapato and Roses Lake. You will also see a turn off for Antilon Lake.
All 3 offer good fishing with Roses providing the most productive fishing at the moment and the biggest fish. Antilon is up in the hills and provides good fishing for browns and a chance to get away from the crowds. Don't know much about Wapato other then it has been fishing tough this year.
I don't want to be a downer but Roses has been a skunk for me the last two times this spring and once last year.
My neighbor on the other hand has had good luck using bait at Roses. ugh!
Antilon is a neat little lake, poor shore access, but if ya got a float tube or toon. It would be fun to fish.
This time of year the smallies in lake Chelan will be just off butt floss beach, look for the rock piles and stumps.
I was at Roses last Nov when 2 trucks rolled up and dumped in thousands (I forgot how many - 4500?) of catchable bows. It was quite a site. I'm sure my 4 year old daughter has a skewed understanding of "where do fish come from?" from watching this.
As far shore access -- I have only one data point (there may be lots that I don't know about), but you could cast from the doc at the "public access" or there was a good point just to the left of the dock where I was casting from. I didn't catch anything -- the newly planted bows were jumping everywhere, but from a state of shock, not feeding.
