Thanks for the responses. I should have been clearer, I bought a DE trout stamp and fishing license planning to check out the White Clay Creek FFO (there is one, according to DE website) section south of the PA border. Assumed, being from PA, a FFO section could be fished year round, but can't seem to confirm. I'll see if I can get an official answer over the phone or email.
"White Clay Creek from a point 25 yards above Thompson Bridge at Chambers Rock Road to the Pennsylvania state line is designated as a fly-fishing only trout stream (restricted trout water). It is unlawful to use any metallic, plastic or rubber spinners, spoons, lures, plugs or natural bait or to use more than two (2) flies on a line at any one time." http://www.eregulations.com/delaware/fishing/freshwater-trout-fishing/
