We paddled Sugar Creek on July 5, 2010, from Deer Mill Covered Bridge to the Narrows, just before Turkey Run State Park. The put in point at Deer Mill is ideal; plenty of parking just up the hill, a great launching area, no problems. The take out point, Brush Creek, just a bit up from the Narrows Covered Bridge, was decent, but there is no available long term parking; all parking spots are limited to 20 minutes. I don't have a clue what they are expecting you to do here. I wound up parking my car on the edge of the road just to the west of the "parking" area.
The stream flow was 386 cfs, and the height on the Crawfordsville guage registered 2.3 feet. I would call this nearly ideal. We never had to drag that canoe at all.
This is a great section, although not exactly quiet due to its popularity - a run on a weekday would probably be more serene. The day we went, the Monday after the 4th of July, there were a lot of folks out, but that didn't really detract too much from the scenery, which is beautiful, especially through Shades State Park (the first half of the section). It took us about 4 hours, and we stopped twice to rest or have lunch.
There is a canoe camp at Shades State Park, if you wanted to start further upstream and make a two-day trip of it; and there are least two other takeout points in or near Turkey Run State Park, so there are opportunities for all sorts of trips from short to long.
