Haven't fished it this year (no pass), but believe you have to use barbless hooks (to help survival rate of fish caught). I just crimped them down with my pliers. Caught a couple pushing 4 lbs last year on black buzz baits. Really nice park. Good luck if you give it a go.
I go there a few times every month too. It is a nice place for LMB, Cats and Carp.
In June they had a fishing derby there (adults and kids) and I saw quite a few big fish coming out of the water. The winner was a 23" Cat. A lot of cats in the 20+" range, and some monster carp.
The rangers asked NOT to return the carps, once they are invasive and they have been trying to get rid of them.
Brought my rod and tackle to work today, We were thinking about that place all day 3'oclock storm rolls in no fishing today. Tried to out run the rain home, got to punderson poured before we got out of the truck, hightailed it to aquilla downpoured in 5 minutes. going to my my farm pond spot now got the itch today!
