Back to the orginal topic. I did some reading and found an article here
Litton's Fishing Lines: Early Season Northern Pike New Jersey Region
The interesting parts to me are
"Pike spawn shortly after ice-out, moving into shallows as early as late February, depending on when ice melts. In lakes and reservoirs they seek out the mouths of creeks and streams, and areas of residual vegetation in shallow coves. Key spots at Spruce Run are the entryways of its 5 feeder streams, especially Spruce Run" ..."Pike will not usually bunch up at a creek mouth. The entire football field length of water inside the Spruce Run Creek mouth and jetty is worthwhile, for example, and we catch most of our pike towards the end of it on the reservoir side."
"Early spring is the habitual time for river pike to move upstream, not to a headwater destination as salmon do, but into slow backwaters and in lakes, tributary streams. A friend reported that a creek in Verona hosted 3 foot, Passaic River northerns in March. Since pike turn upstream for these areas, dams are often great spots to fish. The Wilhousky Street dam on the Millstone River in Manville is worth a shot. Not only does it block migration further upstream, to the left of it facing downriver is a slow, shallow backwater eddy."
If you look at google maps of Spruce Run, you can clearly see the earthern jetty he is talking about and I am sure I could cast out pretty well with some big saltwater flys anywhere along there. I am going to give that a shot as soon as we get some warm weather and I can take time off from work. I will probably check out Verona also because that is not to far from me.
