I didn't get in the water tonight, but drove by this evening to check things out. Water didn't look any nastier than usual. It is what it is - it's the South Platte, but most of the water at union is coming straight out of chatfield, so it's "relatively" clean, despite not looking super pretty. Aside from the one big eddy on surfer's left that always has swirling debris, didn't seem to be much else floating in the water. Most of those debris looked like sticks - some trash, too - though again, wasn't up close. Two of the waves in particular looked like they'd be good fun - comparable to anything at Golden at this point, and I'd imagine alot less busy. Nothing looked especially challenging to the beginning boater.
