Likely minimal flow; likely too low for any reasonable whitewater experience.
Three options:
1) HIGHLY VISIBLE (from the store, 76th street, and the sidewalk): in front of Richlonn's/Goodyear: The uppermost reasonable point of access is at the upstream edge of the parking lot (closest to 76th Street). Load into your boat from the sloped cement. (A 'stop-block'/step of concrete may aid in keeping your boat from launching before you are ready).
2) Slightly less conspicuous: From behind Richlonn's/Goodyear (west end of building): the first 'jump' is right there. Either put-in immediately above it, or carry up along the building to the above-mentioned spot.
3) Moderately conspicuous: From the Starbuck's parking lot: Park in the northwest corner (against the creek). Carry down to the cement ditch, then put-in immediately (to be just upstream of the first 'jump'), or carry upstream to a few more paddle strokes before the first 'jump'.
