when do you think the spawn will start in pennsylvania???

Will it start in different areas in pa, i live in south east pennsylvania,

around montgomeryville, what do you think??

My guess would be somewhere around the beginning of May (depending on the size of the body of water your fishing). I've been tracking the spawn on the 505 acre lake I fish down here in MD over 10 years now and seems to be when the water usually hits the magic number.

We still have quite a while yet.  Water temps are barely in the 40's here and with nights getting down to freezing temps, it will be a slow process.

Beginning of May is a good guess.  Look for 55-60 before seeing any consistent bedding.
