Open/Close SAGINAW RIVER & BAY, MICHIGAN
(This section includes Stage of RAP development, Beneficial Use Impairments and their delisting targets, and information on whether the AOC has been accurately mapped.)
Stage of RAP Development: 1

Are electronic maps available that include the AOC's geographic boundaries and associated sources of pollution? No

Beneficial Use Impairments (BUI):
(The BUI will appear underlined if a delisting target has been determined.
If underlined, click on the BUI to display the delisting target.)
Restriction on Fish & Wildlife Consumption
* Levels of PCBs and dioxin in walleye taken from the Saginaw River/Bay are equal to or less than the levels foundin comparable fish taken from other areas of the Great Lakes not listed as AOCs.
* PCB and dioxin levels in fish tissue from caged-fish studies in the Saginaw and Tittabawassee Rivers indicate thatthe former sources of these contaminants have been effectively controlled and/or remediated.
Tainting of fish or wildlife flavour (taste and odor concerns)
Taste and Odor problems reported by anglers for any species taken from the Tittabawassee River downstream from Midland and the Saginaw River/Bay represents less than 1 in 10,000 of the estimated total annual catch for that species for three consecutive years. In addtion, no specific sites of fish tainting have been identified that would justify remedial action.
Degradation of Fish and Wildlife Population
* Walleye-Increase abundance in the bay, ultimately through natural reproduction, such that growth rates approximate more closely statewide averages for this species and reflect improved use of available forage in the bay.
* Yellow Perch-A sustained annual harvest of 750,000 pounds per year with increasing abundance of larger, faster-growing individuals.
* Lake Sturgeon-Documented evidence of natural reproduction in the Saginaw River.
Bird or Animal Deformities or Reproductive Problems
* Bald eagles- The reproductive success of bald eagles in the Saginaw Bay area is equivalent to that found in other Lake Huron coastal areas in Michigan.
* Herring Gull-PCB levels in herring gull eggs taken from Saginaw Bay area nest sites are not significantly higher than those found in other Lake Huron sampling locations.
Degradation of Benthos
Sample of mayfly nymphs collected in the open waters of Saginaw Bay exceed 30/m 2 for two consecutive years, based upon established sampling methods.
Restrictions on Dredging Activities
The level of contaminants in Saginaw River/Bay sediments no longer imposes additional costs due to requirements for the removal, confinement, and remediation of dregde spoils.
Eutrophication or Undesirable Algae
The average concentration of total phosphorus for three consecutive years is 15ug/L or less, in accordance witht the supplement to Annex 3 of 1978 Great Lakes Water Quality Agreement.
Restriction on drinking water (taste, odor, or other problems)
The N:P ratio measured in Saginaw Bay is at least 29:1 for three successive years, indicating that conditions once favoring blue-green algal populations responsible for former taste and odor problems in drinking water withdrawn from the bay are no longer present.
Beach Closings
* Three consecutive years of testing for E. coli bacteria, an indicator of the presence of harmful microorganisms, confirm that state water quality standards for full-bogy recreation are being met in Saginaw River.
* No More than three swimming beaches are closed per yearand closures last no more than two days each in Saginaw Bay.
Degradation of Aesthetics
(see Eutrophication or Undesirable Algae)
Degradation of Phytoplankton & Zooplankton Populations
(see Restrictions on Drinking water)
Loss of Fish and Wildlife Habitat
* Dissolved oxygen levels in the river meet or exceed the minimum state water quality standard of 5.0mg/L during the critical summer months.
* Critical coastal marsh areas are adequately protected-At least 60% of the coastal marsh areas (below the 585-foot contour) and adequate upland buffers representing essential fish and wildlife habitat is preserved through public ownership, covered under conservation easements, or otherwise protected under agreements with landowners.
* The most vulnerable portions of the remaining 40% of the essential coastal marsh areas have been clearlyidentified so that governmental agencies, local conservation/environmental organizations, and concerned citizens can monitor their status, enforce existing laws, and conduct public educational programs to better protect these areas.
