Beat me to the punch. I went through this last year with a son who was a runner…good enough for some D1 but not necessarily the ones he wanted…and a good student but not nearly on par at all with your daughter. I would suggest looking at the rankings for the top D3 programs (https://www.ncaa.com/rankings/swimming-women/d3). Then figure out the following: city/suburb/college town/small town and big/medium/small. And what she wants (or thinks she wants to study). Then you need to dig in and come up with a list. (I took this on for my son…made a spreadsheet).
Good luck!
