10 kcfs About half of all streams and sloughs in nontidal floodplain become impassable at 10,000 cfs, blocking access from main stem to floodplain for fish, fisherman, and hunters. Extent/reach: Floodplain streams, sloughs, and lakes along 86 river miles (mile 21-107).
11 kcfs Flow needed to provide sufficient depths at tributary mouths for fish to move between the tributaries and main channel.
13 kcfs Barges and large boats cannot navigate the river (at Blountstown gage of 6 feet or lower, which is approximately equivalent to 13,000 cfs at Chattahoochee gage). Reach: Upper 86 miles (mile 21-107), especially at problems reaches (e.g. near Corley Slough).
15 kcfs Most Tupelo-Cypress swamps in nontidal reaches of the annual floodplain are exposed and no longer inundated at 15,000 cfs. Inundation in wetland forests March-May is important habitat for the primary fish spawning season, and also maintains healthy forest structure and species composition in swamps. Extent/reach: Approx. 19,000 acres of Tupelo-Cypress swamps bordering 57 miles of river (mile 21-78).
21 kcfs Releases to the Apalachicola River approximate or exceed inflows into the basin whenever basin inflows approached 21,000 cfs or lower during the Gulf Sturgeon spawning period.
29 kcfs The extent of connected aquatic floodplain habitat increases substantially at flows above 29,000.
5.0 kcfs Minimum flow from Woodruff Dam. Swift Slough is disconnected from the main stem of the Apalachicola River
5.6 kcfs Level needed for the Swift Slough to remain minimally connected to the river. Dissolved oxygen declines to lethal levels.
6 kcfs More than 85% of all streams and sloughs in nontidal floodplain become impassable at 6,000 cfs, blocking access from main stem to floodplain for fish, fisherman, and hunters. Extent/reach: Floodplain streams, sloughs, and lakes along 86 river miles (mile 20-106). In many areas of the estuary, salinity levels increase to intolerable or lethal levels for estuarine biota (oysters, submerged aquatic vegetations, benthic invertebrates, etc). Extent/reach: Nearly 100 miles of brackish-water streams in the lower Apalachicola River and distributaries, plus approx. 110,000 acres of bays and sounds in the Apalachicola Bay system.
8 kcfs Low flow operations protocol implemented when flows approached levels less than 8,000 cfs to minimize impacts to mussel species.
9 kcfs In some areas of the estuary, salinity levels increase to intolerable or lethal levels for estuarine biota (oysters, submerged aquatic vegetations, benthic invertebrates, etc). Extent/reach: Nearly 100 miles of brackish-water streams in the lower Apalachicola River and distributaries, plus approx. 110,000 acres of bays and sounds in the Apalachicola Bay system.
