According to USA Swimming's national age group record listing
www.usa-swimming.org/.../SCY_boys_girls_NAG.pdf
... the 15-16 record for 50 free is 20.20.
They don't track 15-16 records for the 50 fly.

U might try Swiminfo.com and look at all their records for high school or try ur local url's for swimming to see what records are in ur area, Speedo or USA swimming has senior sectional meets that have allot of 16 yr olds swimming them also. Good Luck. Probably someone else can help u better than I. These are just some suggestions from what I have seen surfing around.
