Normcar, this is just a "guess" but it makes sense.
We know a "creek" runs along the park n ride, goes under ground there and must come out someplace else. We also know that Sams Canal runs along Maple between 7th and where the waste water treatment plant is near the end of 10th. (making 8th, 9th and 10th Streets dead ends)
on my map below, red indicates the areas where we know water is flowing. The green is where I am guessing where the underground portion runs
Found this info:
Sam's Canal, dug in the 1920s, meanders South through town, until it cuts West just past City Hall.
