Possible infection.: It appears as your bruises might be getting infected. If so, you will need to be treated with antibiotics. Also if you got exposed to either Poison Oak, Poison Ivy, or Poison Sumac while going to or from river, you might get similar rash. Allergies might do the same.

Possibly unrelated: It's not clear that the bruises are at all related the rash you've noted. It may be purely coincidental timing and location wise between the bruises and subsequent rash. It's very possible that you have developed a folliculitis, inflammation of the base of the hair follicles, related to an exposure in the water. You first may want to give a go of any over-the-counter antimicrobial soap.
