Fished Here Today.. Ice Was A Honest 5  1/2" Where I was Fishing.. Caught 7 Gills With 2 Possible Cleaners.. 9 FOW  40 / 50  Yrds. Off The Boat Ramp.. NW/

I Copied this from the fish commission website:
 
Sugar Lake is a 90 acre natural lake located in Wayne Township in south central Crawford County. The lake is accessible from Routes PA 27 and PA 173. There is a Pennsylvania Fish & Boat Commission owned boat launch with limited parking for about 12 vehicles with trailers located on the western shore. Shore fishing access is severely restricted by wetlands and private residences. The lake is currently restricted to motors of 6 horsepower or less or electric motors.
 
Burn away!!!

Chain Pickerel are easy to catch in that lake, and we caught very many last year through the ice. They are invasive to that lake and to this part of the state.  Sure they can be fun to catch, but they are overrunning that lake of other native species, something to think about. Use tip ups with 3-5 inch live baits near weeds. Catch em all!!!!

3/4  to  1 in. of black ice as of 12/29/13  ....NW/
