- The largest source of acid mine drainage in our area is the Jeddo Tunnel which drains into the Little Nescopeck Creek, a tributary of the Nescopeck Creek.
- What we call the Jeddo Tunnel is actually a series of inter-connected tunnels; the first was begun in 1891 and the final one was completed in 1934.
- The original purpose of the tunnel system was to use gravity to drain water from the underground mines which once were in operation throughout the Hazleton area.
- Even though the underground mines which were drained by the Jeddo Tunnel are no longer in operation, surface water still enters into the system.
- Water coming out of the system contains significant amounts of iron, aluminum, manganese, and sediment.
- The average flow from the Jeddo Tunnel is 30,000 to 40,000 gallons per minute although peak flows in excess of 100,000 gallons per minute have been recorded.
- The tunnel system has a total drainage area of 32 square miles.
USGS replaced the old abandoned gaging station with a new station in December 2022. To view the flow in cfs (cubic feet per second) from the tunnel outfall click on the link to the USGS Streamflow website.
