I am not sure if the attachment works but here are details of the proposal direct from Boarder Paving. The map isn't a great visual for showing how the water likely flows through the gravel from the Clearwater river to the headwater springs on the North Raven but this pit will basically intercept and "choke" it off.
Also note that three other quarters in the area are already owned by gravel operators and I would expect every other quarter in the flats will be purchased at $1,000,000 plus a pop. No hard feelings for guys selling out....it would be pretty tough to turn down what gravel operators are paying.
