Discharge ratings for control gates at Mississippi River lock and dam 12, Bellevue, Iowa

The water level of the navigation pools on the Mississippi River are maintained by the operation of tainter and roller gates at the locks and dams. Discharge ratings for the gates on Lock and Dam 12, at Bellevue, Iowa, were developed from current-meter discharge measurements made in the forebays of the gate structures. Methodology is given to accurately compute the gate openings of the tainter gates. Discharge coefficients, in equations that express discharge as a function of tailwater head , forebay head, and height of gate opening, were determined for conditions of submerged-orifice and fee-weir flow. A comparison of the rating discharges to the hydraulic-model rating discharges is given for submerged orifice flow for the tainter and roller gates.

Supplement to floods in the upper Des Moines River basin, Iowa

Data on the East Fork Des Moines River for the August 1979 flood between river miles 330.4 and 408.8 is being published as a supplement to the report "Floods in the Upper Des Moines River basin, Iowa" (Schwab, 1970). Elevation profiles of the 1979 flood, along with previously published profiles, are shown in figures 2-4.

Floods in the Skunk River basin, Iowa

Evaluation of flood hazards, and the planning, design, and operation of various facilities on flood plains require information on floods. This report provides information on flood stages and discharges, flood magnitudes and frequency, and flood profiles for the Skunk River and some of its tributaries. It covers the Skunk -- South Skunk Rivers to Ames, and the lower reaches of tributaries as flows: Squaw Creek, 8.2 miles; Indian Creek, 11.6 miles; North Skunk River, 83.2 miles; Cedar Creek, 55.8 miles; and Big Creek, 21.7 miles.

Water resources of south-central Iowa

The objective of this report is to present information on the water resources of south-central Iowa that will help solve the supply problems of the water users in the region and that will aid planners and water managers who must consider water resources on a regional basis. The information presented includes the availability, quality, and utilization of water from all known sources and the future demands upon the water resources.

Floods in the Big Creek basin, Linn County, Iowa

Flood information for the Big Creek basin in Linn County, Iowa, should be of use to those concerned with the design of bridges and other structures on the flood plains of the streams. Water-surface profiles for the flood of May 1974 are given for Big Creek and its major tributaries, East Big, Crabapple, Elbow, and Abbe Creeks. The May 1974 flood was at least a 50-year flood on East Big Creek and along certain reaches of Big and Abbe Creeks. Also included for Big Creek are a profile of the December 1971 medium-stage flow and a partial profile for the minor flood of July 1971. Profiles for the low-water condition of October 26, 1972, are shown for all reaches. Water-surface profiles for the 25- and 50-year floods are estimated in relation to the May 1974 flood.

Flood of June 27, 1975, in City of Ames, Iowa

On June 27, 1975, the city of Ames and vicinity sustained severe flooding from Squaw creek and the south Skunk River. The storm which preceded the flood was net particularly outstanding in its intensity or duration. However, antecedent conditions plus the timing and direction of the storm were "ideally tuned" to cause the flood. In terms of magnitude of discharge as well as of damages this was the most severe flood on record, with losses estimated by city and Iowa State University officials at over a million dollars. The most unfortunate loss involved the drowning of a young person. The peak discharge at the Squaw Creek station, 206 mi 2 (534 km 2 ), was measured at 11,300 ft 3 /s (320 m 3 /s), which is 1.6 times the 100-year flood. The south Skunk River above the confluence with Squaw creek, 315 mi 2 (816 km 2 ), peaked at 5,330 ft 3 /s (151 m 3 ). The recurrence interval of this discharge is 6.0 years. The peak discharge on the South Skunk River below the confluence with Squaw creek, 556 mi 2 (1440 km 2 ), was 14,700 ft 3 /s (416 m 3 /s), which is 1.1 times the 100-year flood.

Floods in the Iowa River basin upstream from Coralville Lake, Iowa

Flood information is reported for 207 miles of the main stem, 23 miles on the West Branch, and 23 miles on the East Branch, of the Iowa River. The information will be of use to those concerned with the design of bridges and other structures and the conduct of various operations on the flood plains of the streams. Included in the report are flood-peak records, gaging-station records, and water-surface profiles. Outstanding floods treated in this report are the 1954 flood which is the greatest known in the upper reaches of the Iowa River, the 1969 flood which is the greatest flood in recent years in the central reach of the river, and the 1947 flood which is the greatest flood recorded, excepting the 1918 historic flood, in the lower reaches of the river. Selected data are also given for the 1918 flood, the greatest flood recorded on the Iowa River. Flood profiles for the main stem include those for the 1947, 1954, 1969, the computed 25- and 50-year floods, and a partial profile for the June 1972 flood. On the West Branch Iowa River, profiles are shown for the 1944, 1969, the computed 25- and 50-year floods, and a partial profile for the June 1954 flood. On the East Branch Iowa River, profiles are shown for the 1954, 1969, the computed 25- and 50-year floods, and a partial profile for the June 1944 flood. Low-water profiles are shown for all reaches.

Flood of August 2, 1972, in the Little Maquoketa River basin, Dubuque County, Iowa

Flood peaks with magnitudes from 2 to 3 times the SO-year flood occurred on streams in the Little Maquoketa River basin for the flood of August 2, 1972. Up to nine inches of rain fell in the headwater of the Middle Fork tributary with six to seven inches occurring over most of the Little Maquoketa River basin. The flood peak elevation at the gaging station near Durango exceeded the 1925 flood of record by 1.7 feet. Flood damages were extensive to crops, roads, and bridges. Many of the homes in Durango, Daytonville, and Sageville were inundated to some extent and were evacuated. Flood damages were estimated to be over one million dollars. No loss of life or personal injuries were sustained. Flood-peak discharges at 12 sites, basin rainfall, a description of the 1972 flood, brief accounts of other major floods in the basin, maximum flood peaks in northeastern Iowa, selected flood-frequency data, and annual floods of record at 5 sites are given.

Floods in the Rock River basin, Iowa

This report contains flood information for the Rock River basin in Iowa, it updates and supersedes the 1967 report "Floods in Rock River basin, Iowa" by P. J. Carpenter. The occurrence of an outstanding flood in 1969 and the acquisition of additional flood data in the basin prompted the preparation of this report. The 1969 flood, the greatest flood on the Rock River in at least 45 years, is nearly equivalent to a flood of a 50-year recurrence interval. The 1953 flood was the greatest recorded on Otter Creek. This flood was 1.8 times the 50-year recurrence interval discharge at the gaging station near Ashton. Flood information is reported for 49.8 miles (80.1 kilometers) on the main stem, 49.6 miles (79.8 kilometers) on the Little Rock River, and 33.0 miles (53.1 kilometers) on Otter Creek. This information is useful to those concerned with the design of bridges and other structures and those involved in regulatory or planning activities on the flood plains of the streams. Included in the report are flood-peak records, frequency curves, water-surface profiles, and bench mark data. Flood profiles for the Rock River include those for the 1962, 1964, 1965, 1969, and the computed 25- and 50-year floods. On the Little Rock River and Otter Creek, profiles include those for the 1969 flood and the computed 25- and 50-year floods. Low-water profiles are shown for all reaches.
