This web site is better for WI frog locations.

The Pickeral is confirmed in the county we are talking about but I
would sure like to sit with one for some time at KVR because I have
found so many leopard frogs that only occasionally chuckle up here. A
Pickeral find is also important because the people that manage KVR
care so much about the land and this frog is associated with "good" land.
The other WI frogs I am missing from KVR on the south 40 acres are
"Bull", "Mink", and "Cricket". I don't expect to ever find those but
many locals believe their "Greens" are "Bulls".
