The Old Frederick Road Bridge trims 1.8 miles from Daniels of mostly flatwater/moving water from the top of the Oella stretch. The Old Frederick Road Bridge is where Old Frederick Road (Howard Co.) and Hollofield Road (Baltimore Co.) meet. You'll still have a good four miles down to Ellicott City, and almost seven beyond that should you choose to continue to Elkridge.
