Shore fishing close to Sammamish

[willvv]

Hi,

I have some friends visiting who would like to do some fishing tomorrow. We would be fishing from the shore and were wondering if there's a place around Sammamish where we can fish some trout.

I was looking at Rattlesnake lake and seems like a nice area, but I'm not sure if the water would be too warm.
I assume going to Lake Sammamish would have too many people and would be hard to fish anything. Right?

It doesn't have to be trout, anything that can give us some fun would work perfectly :P

Any recommendations?

Thanks a lot
