This is above the Fall Creek Reservoir.
Each fall the USACE draws down the reservoir to aid out-migrating Pacific Lamprey amocetes November to December. The I-II stretch below the reservoir gets a bump, but it has no impact on the inflow upstream of the reservoir which this listing describes.
To determine the water in this run, you must look at the INFLOW to the Fall Creek Reservoir, available on the USACE website here:

When it's raining, there is a correlation between the outflow below the reservoir and the inflow above it, so the linked gauge here can be useful. But it's not a 1:1 and the inflow to the lake should be checked to be sure before making the drive.
