Fished at Rock Creek.  Temps in 60's today.  Very unusual weather for this time of year.  Water clear to 12+ feet.  Could see the bottom of the lake in most places.  Caught several Perch and a few bluegill.   Had a couple large trout hit but did not land them.  Had about 5 acres of open water.  Rest of lake frozen on top and about 1/2" to 1" thickness.
