Reservoir and Flood Question

[Mayfly]

Recently I had a discussion with a friend about the last 3 floods in the Catskills and the potential for avoiding them by managing the reservoirs. Now I'm not asking for opinions on 'management', 'flood control', 'water levels', 'flows', etc.

What I am asking for, if someone knows, is mathematical information related to the willingness to release water from the reservoir given advanced warning from the US Weather Service. So let's say that under the following condition and information the person in charge of water releases gets the following:

- It is Monday, June 1st.
- Both the Pepacton and Canonsville reservoirs are at 95% capacity.
- The US Weather Service issues a severe weather warning that a hurricane type storm system will definitely hit the area on Sunday, June 7, with 8 to 10 inches of rain.

Between the warning and the arrival of the storm, what is the amount of water that may be safely released per hour? How much water can safely be released and what will be the capacity(%) when the storm arrives? Also, if 8 inches of rain does fall, starting 12:01 Sunday morning and ending Sunday at noon, how much water will get dumped into the reservoirs?

Thanks to anyone who takes the time figuring out some answers.
