for the record, the only development that affects this part of the Bushkill is any house that has had a well drilled. Most of the development is on American water distribution or city water depending on where the folks live. This section has also suffered from Storm water discharge from all the water dumping into the creek. One of the reasons this sections hatches are or have become so bad over the years, development and dried up creek bed syndrome.
This section has suffered from dewatering several times in the past since the 70's. Pump failure caused one episode, A Lightening strike did another, the other one if memory serves me correctly was during a drought several years ago . Every time DEP issues a permit this stream suffers.
To get a matter of perspective , that quarry alone is enormous, and also very, deep. Like has been said it will literally take years for that quarry to fill up to even start to make back pressure. This is what happens when man gets greedy for money and cares nothing for his natural world. Even when the creek goes under in this section it still comes out near Upstream Farms/ section.
Is it bad? You damn right it is. Can it be fixed? The pumps either have to run, or don't run the pumps any longer and let the hole fill up then wait for years. The other trouble is that fines are definitely way too lenient towards the Quarry when this happens , they just drag it out an pay the fine .
All for the grace of money. Most of the limestone from that quarry is used for cement and some crushed stone ect.
