Martinlf, thanks should really go to ebroesicke here. He and his Monocacy chapter have really been active on this. I just gave a little background that I was aware of but he's really been leading the effort to inform the mayor, etc. of why wild trout are important and a true asset to Bethlehem and shouldn't be jeopardized because of a few vastly uninformed people spreading misinformation.
Also CLSports, I'm pretty sure the survey the WCO is talking about is the population sampling survey they periodically do. I don't believe it's a specific report on the issue of flooding but rather based on the data from the fish survey they've kind of correlated the several missing or diminished age classes of fish to the several large floods that have happened in the last 10-15yrs. The same goes for the Bushkill in Easton. However an ongoing (and increasing) problem for both streams (and just about all the Lehigh Valley streams) that has likely contributed to the overall decline of the population as a whole is the sediment, which not only buries spawning grounds but also effects many of the hatches. In that regard some of the floods may have actually helped (short term) some by better moving that trapped sediment down out of the system. Removing more and more of the numerous obsolete dams that plague each LV stream will go even further towards hopefully reversing the sediment buildup trend.
