Additional Comments
THIS STREAM IS POSSIBLY BARGER CREEK BUT MAPS DO NOT REFLECT BARGER CREEK IN THE RIGHT AREA IF SO. THIS IS A DAM THAT FLOWS THROUGH 2 SEPARATE CULVERTS SEPERATED BY AN 8' OPENING. INLET VELOCITY WAS MEASURED AT INLET 2 (SEE DRAWING). RIGHT APPROACH BEHIND PRIVATE GATE SO IT WAS ESTIMATED.
