FWIW,,,there are "Jeckyl and Hyde" habitat conditions in Alberta this year. Central Alberta (parkland region) and northern Alberta are in much better shape than southern Alberta prairies this year. Farmers in many areas struggled to get the remains of last years crops off and get this years crops seeded. With the delayed seeding it will likely be a later harvest meaning limited opportunities for field hunts in early Sept. As far as hunting over water, hunting ducks over smaller pothole sloughs ,,,(typically day roosts in or near feeding fields),,, is quite acceptable and no one would give you a hard time about it. Shooting over or near a roost that harbours staging geese is frowned upon by most avid goose hunters.
