Farmington is going to be pretty good walkin access for you. Ogden might be ok but I think that with all the phrag and crap out there, it might not be worth a walking trip until later in the year when you can get into ducks on the west side. You could also do Bear River, Public or one of the places to the north... they seem to have pretty good dike systems too. Good luck... thats awesome of you to take those guys out.
