I have a friend who has a cabin on the lake near arlington (isn't that Snohomish county?).
I've benn there many times and caught small bass, cutts, bows, and kokes there (cutts can get pretty nice sized). I use a row boat when I go, and never have any problems with the wind. Sometimes the jet skiiers and motor boats can be annoying. You could probably do the boat launch - but I've never tried it myself. In general, this is a beautiful lake and is generally very quiet with decent fishing. Hot summer weekends will draw some small but loud crowds.

Hope this is the lake you were referring to...
