Congrats on the new drift boat! Pavati is nice, but too bad you didn't get a Koffler like Kyle's old boat. J/k.
The day island park to d st. in Springfield is a pretty easy run as long as you get lined up right at the rapids that plumb mentioned. Just stay to the pizza parlor side and you'll be fine, it looks intimidating, but it's fairly deep. Still best to go with a buddy who can row you down it first tho, I'd suggest you give a pm to plumb.
Nice thing about that particular drift is that it's short so you can go before or after work, not a big deal at all. Plus you can hook into some summers or even a nook.
Best,
