32.5 The flow at this level is about 62,000 cfs and has a 1 percent chance of happening in a given year (aka 100-year flood).
30.6 The flow at this level is about 56,000 cfs and has a 2 percent chance of happening in a given year (aka 50-year flood).
28 Above 28 ft, expect major flooding along Riverview Avenue area and numerous homes and businesses in Mapleton. Flooding of roads adjacent to the Siuslaw River in the vicinity of Mapleton is likely. Flooding of Highways 126 and 36 will be significant.
26 The flow at this level is 42,000 cfs and has a 10 percent chance of happening in a given year (aka 10-year flood).
25 Above 25 ft, expect widespread flooding, including several homes and structures in low areas of Mapleton. Many sections of Highway 126 from Tiernan to Mapleton, along with Hwy 36 north of Mapleton begin to flood. Flooding may be exacerbated during high tide.
23.2 The flow at this level is about 35,000 cfs and has a 20 percent chance of happening in a given year (aka 5-year flood).
22 Above 22 ft, expect widespread flooding of low-lying land. Several homes and structures in low areas of Mapleton start to flood. Numerous rural roads along and near the Siuslaw River will likely be flooded, and water begins to cover the lower sections of Hwy 126 at this stage. Flooding may be exacerbated during high tide.
20 Above 20 feet, expect water over East Mapleton Road. Flooding of some low-lying homes and structures begins. Flooding may be exacerbated by high tide.
19.1 The flow at this level is about 24,600 cfs and has an annual chance of 50 percent (aka 2-year flood).
18 Above 18 ft, expect minor flooding of low lying dairy land along with some structures right along the banks of the Siuslaw River in and near Mapleton.
