Flood-inundation maps for Cedar Creek at 18th Street at Auburn, Indiana

Digital flood-inundation maps for a 1.9-mile reach of Cedar Creek at Auburn, Indiana (Ind.), from the First Street bridge, downstream to the streamgage at 18th Street, then ending approximately 1,100 feet (ft) downstream of the Baltimore and Ohio railroad, were created by the U.S. Geological Survey (USGS) in cooperation with the Indiana Department of Transportation. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science web site at https://water.usgs.gov/osw/flood_inundation/ , depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgage on Cedar Creek at 18th Street at Auburn, Ind. (station number 04179520). Near-real-time stages at this streamgage may be obtained from the USGS National Water Information System at https://waterdata.usgs.gov/ or the National Weather Service Advanced Hydrologic Prediction Service at http://water.weather.gov/ahps/ , although forecasts of flood hydrographs are not available at this site (ABBI3). Flood profiles were computed for the stream reach by means of a one-dimensional step-backwater model. The hydraulic model was calibrated by using the most current stage-discharge relation at the Cedar Creek at 18th Street at Auburn, Ind. streamgage and the documented high-water marks from the flood of March 11, 2009. The calibrated hydraulic model was then used to compute seven water-surface profiles for flood stages referenced to the streamgage datum and ranging from 7 ft, or near bankfull, to 13 ft, in 1-foot increments. The simulated water-surface profiles were then combined with a geographic information system digital elevation model (derived from light detection and ranging [lidar] data having a 0.98-ft vertical accuracy and 4.9-ft horizontal resolution) to delineate the area flooded at each water level. The availability of these maps, along with internet information regarding current stage from the USGS streamgage at Cedar Creek at 18th Street at Auburn, Ind., and stream information from the National Weather Service, will provide emergency management personnel and residents with information that is critical for flood response activities such as evacuations and road closures as well as for postflood recovery efforts.

Cedar Creek at Cedartown, Georgia, floodflow characteristics from West Girard Avenue to the Georgia Avenue Relocation

In cooperation with the Highway Division, Georgia Department of Transportation, the U.S. Geological Survey determined the backwater effects of existing bridges and dikes on Cedar Creek at Cedartown, Georgia, for the reach from West Girard Avenue to the Georgia Avenue relocation. The maximum backwater effect for the bridges was 1.7 feet in the upstream approach at the Seaboard Coastline Railroad bridge as a combined result of the Georgia Highway 278 bridge and the Seaboard Coastline Railroad bridge. The maximum effect from the existing dikes was 0.7 foot at the approach section of Georgia Highway 278.

A one-dimensional, steady-state dissolved-oxygen model and waste-load assimilation study for Cedar Creek, Dekalb and Allen counties, Indiana

The Indiana State Board of Health is developing a State water-quality management plan that includes the establishing of limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Cedar Creek was used to develop alternatives for future waste loadings that would be compatible with Indiana stream water-quality standards defined for two critical hydrologic conditions, summer and winter low flows. All point-source waste loads affecting Cedar Creek are in the four incorporated municipalities of Auburn, Garrett, Huntertown, and Waterloo, in a primarily agricultural area. Avilla, because of its distance from Cedar Creek, does not significantly affect the water quality of the modeled segment. The model indicates that the dissolved-oxygen concentration of the Auburn wastewater effluent and nitrification are the most significant factors affecting the dissolved-oxygen concentration in Cedar Creek during summer low flows. The observed dissolved-oxygen concentration of the Auburn wastewater effluent was low, and averaged 30 percent of saturation. Whether the effluent is aerated before discharge will ultimately define the waste-load assimilative capacity of Cedar Creek. Projected nitrogenous biochemical-oxygen demand loads, from the Indiana State Board of Health, for the Auburn and Waterloo wastewater-treatment facilities will result in violations of the current instream dissolved-oxygen standard (5 milligrams per liter), even with an effluent dissolved-oxygen concentration of 80 percent saturation. Natural streamflow for Cedar Creek upstream from the confluence of Willow and Little Cedar Creeks is small compared with the waste discharge, so benefits of dilution for Waterloo and Auburn are minimal. Stream reaeration capacity is not sufficient to maintain an average dissolved-oxygen concentration of at least 5 milligrams per liter, the State's water-quality standard for streams. The model also indicates that, during winter low flows, ammonia toxicity, rather than dissolved oxygen, is the limiting water-quality criterion in the reach of Cedar Creek downstream from the wastewater-treatment facility at Auburn and the confluence of Garrett ditch. Ammonia-nitrogen concentrations predicted for 2978 through 2000 downstream from the Waterloo wastewater-treatment facility do not exceed Indiana water-quality standards for streams. Calculations of the stream's assimilative capacity indicate that future waste discharge in the Cedar Creek basin will be limited to the reaches between the Auburn wastewater-treatment facility and County Road 68.

Water-level changes in wells along the west side of the Cedar Creek anticline, southeastern Montana

Water levels have been measured periodically in wells along the west side of the Cedar Creek anticline in southeastern Montana since 1962-64. The measurements show the response of the Fox Hills-Hell Creek aquifer of Late Cretaceous age to withdrawals for domestic, stock, and industrial uses. Water levels were as much as 109 feet lower in 1975 than they were in 1962-64. During the same period water levels lowered by 10 feet under about 400 square miles. From 1962-64 to 1969 water levels declined by as much as 133 feet. From 1969 to 1975 water levels rose as much as 46 feet near the outcrop of the aquifer and lowered 10 feet or more beneath about 100 square miles. Decreases in the rate of pumping from industrial wells near the outcrop have caused the water-level rise. Withdrawals from domestic and stock wells have remained the same or increased during the last 14 years and have contributed to water-level declines in areas west of the aquifer 's outcrop.

Cedar Creek at Cedartown, Georgia-- floodflow characteristics at bridge site of Georgia Avenue relocation (supplement to open-file report 75-46)

The May 1974 U.S. Geological Survey open-file report 75-46, "Cedar Creek at Cedartown, Georgia, Floodflow Characteristics at Georgia Avenue, Relocation and Canal Street Extension," prepared at the request of the Georgia Department of Transportation, described the hydraulic characteristics of the Georgia Avenue relocation as constructed in April 1974, and evaluated the effects of three proposed changes in roadway grades at this crossing.
