11.7	Low lying roads near the river will be covered with water from the Wyoming border to the Dingle area. Bottom girders of Border Rd bridge become affected when stage is approximately 11 feet (flow starts to back up from bridge).
10.5	Water may begin to cover portions of Danish Avenue east of Dingle. Near 10.5 feet in stage is where the flat horizontal concrete footings of bridge become inundated (water still flows under bridge uninhibited).
7.5	or 2484 cfs... Water will begin to encroach on Pegram Road just north of Pegram. Lowland flooding of fields and pasture land will occur. Driveways to low lying homes next to the river near Dingle may have water across them. Some basements of low lying homes next to the river will start to have water come in them.
7	or 2184 cfs... River reaches bankful at several locations. Water begins to spill over the river bank causing minor flooding of some low-lying fields.
