Re: Hawaii Freshwater "Clean Sweep"
Freshwater fishing is only available on Kauai and Oahu. (there is also bonefishing) Our peacock bass average around 2 pounds with a 3 to 5 pounder not that uncommon. They feed exclusively on smaller fish so any fly that looks or acts like a little fish works fine. They are not leader shy.
We use 5wt and 6 wt rods and small streamer flys.
The only lake on Oahu is Wahiawa Res (Lake Wilson). It can be fished from shore in some places, but it's a lot easier from a boat.
