Lake Prairie Grove is only open on weekends and cost about $3 per person and I think $5 to put a boat in.
No gas motors allowed. I was told you could not have one on the boat

I think Lake Wedington has a HP limit (maybe under 10) check before you go and it also cost to get into the park.

Been to Bob Kidd once and like the little lake, I never run my motor above a idle, For some reason the wife would prefer to go to beaver.
After you learn how to fish beaver, teach me.

I have not fished Lake Fort Smith but did check it out this summer. No HP limit and I think no cost to use the boat ramp.
