Hi Guys,
Here is the DEP update site for Cannonsville Reservoir "Unusual condition"
Cannonsville
The construction firm drilled three bore holes to test and sample sediments, etc. at the proposed site for the hydroelectric facility. This is at the release chamber of the dam. There is a picture.
When they removed the casing of the third hole the sides collapsed.
Since construction of the dam there has been an artesian well that has sent water up a 6 inch pipe about 200 yards downstream of the dam.
When the casing collapsed the amount of water in the artesian spring decreased.
Some silty water appeared near the release chamber and continues to run silty.
The theory is that the bore hole went into the artesian spring and re-routed the water through the bore hole and then through some gravel where it has picked up some silt.
FERC is in charge of the project.
Reservoir will be drawn down until a repair is completed.
Cold water will be gone in 30 days and reservoir will be empty in about 60 days.
The hope is that there will be a repair completed before that occurs.
Unintended consequences:
Fishing has been fantastic. All rivers fishing well with dries. Amazing how the bugs appeared when the water came.
Cannonsville Release of 1500 cfs
Cannonsville diversion to the city of 730 cfs
Since NYC is diverting Cannonsville water to the city, they are not taking water from Pepacton or Neversink. This keeping the levels of those reservoirs high for this time of year. So, this is keeping those reservoirs in an L1-b level of release. 500 and 150 respectively.
Repairs:
Repairs are to begin this week. A relief well will be driven to try to divert the "leaking" water to a controlled location.
Then, the leaky bore hole will be repaired. No decision yet on the method of the fix.
Time frame:
City is committed to continue the release of water schedule until the repairs have been completed. If Cannonsville is drained there will be just pass through flow. Whatever comes in, goes out. Empty reservoir sometime in late September of early October. This depends on inflows.
When the repairs are completed and approved, they will be able to return to normal operation. I personally think that the repairs will be completed before the reservoir is empty. Maybe more hoping and anything else.
At this point even with an empty reservoir in September the system will still be in L2 condition and those FFMP releases would be made on the other rivers.
Still a lot of things to work out as this process moves forward.
NYC DEP will keep the public informed via the website above.
In the meantime, come on up, get in a boat and enjoy some truly great fishing.
A word of caution!!! The water is COLD!!!!
