Well, to answer the question that I asked the other day, I found a site listing temperatures at the water treatment plant at the mouth of the river (30 ft deep). Today, the temp is 47F. For the past few years, we hit or passed this temp on the following days:
May 23, 2011: 48F
May 14, 2010: 48F
May 11, 2009: 48F
We has a miserable spring last year, and the night bite seemed to start (for me at least) in the last weekend of May. So, my guess is that we may be about 1-2 weeks ahead of "typical", and about 1 week away from good action long-lining sticks...
