ok...i am getting about 3 Gallons per second @ 2.4 psi, ( water level 3" over the pipe ), through the 6 inch x 30 foot pipe...

having measured the pipe, i also re-measured my rough average depth and re-calculated my volume to 44K Ft^3, giving 256K Ft^3 annual overflow...so about 2 million gallons/3=667K seconds, or 185 hours..

so the annual overflow would move through the pipe in about 8 days.
