some nice perch from Altoona earlier this year
Winter gives Altoona fish lockjaw. In 17 years of fishing there I've had 2 good days through the ice. 2.
Open water is a different story, I've had excellent success.
The other thing to consider is the mid-winter slump that typically affects all fishing.
MOON PHASE (34%)
I went to check out the landing on Altoona Park and it looks like winter fest left a bridge in the way of the landing and its frozen in now. Comes out of the ice a foot or two. Looks like people are able to get around it but the landing looked a little rough for my ice shack. There were a permanents and trucks on the ice.
