Flood of March 1968 on the Sudbury, Assabet, and Concord Rivers, Massachusetts

During a 3-day period from March 17 to 19, 1968, a total of 3 to 7 inches of rain fell on parts of eastern Massachusetts. This heavy rainfall, combined with the generally wet antecedent conditions of the spring season and some runoff from snowmelt, caused considerable flooding of the rivers in the area. Property damage in Massachusetts from the flood was reported by the New England Division, Corps of Engineers (1968) to be $28 million. Most of the damage occurred where construction, both industrial and domestic, had encroached upon the flood plains of the rivers. The Sudbury and Assabet Rivers join at Concord, Mass., to form the Concord River (see fig. 1). This three-river system, which is known locally as the “SuAs-Co’’ basin, drains an area of about 405 square miles. The purpose of this report, which is one of a series covering the major flooded rivers in eastern Massachusetts, is to show flood stages and areas inundated by the March 1968 flood, to compare the severity of this flood with past floods, and to show the frequency of floods of given magnitudes which may be expected in the future at gaging stations in the basins. These basic flood data, as compiled, will serve as a broad, sound basis to assist state and local planners in such measures as flood-plain zoning and flood containment and prevention.

Sediment yields of Wisconsin streams

Sediment in Wisconsin streams causes economic and engineering problems in water management and reduces the value of water for nearly all uses. Sediment produces problems such as reduced reservoir capacity, navigation hazards, increased cost of water treatment, property damage, temporary loss of farmland, destruction of feeding and nesting grounds of fish, and destruction of wildlife habitat. Sediment in water also reduces the aesthetic value of surface waters and is detrimental to the State's tourist and recreation industry. The yield of sediment from a drainage basin is subject to many environmental influences. Most sediment results from the weathering and erosion of soil and rock materials. Other factors such as rainfall intensity, runoff rate, topography, rock type, soil characteristics, vegetal cover, and land use also influence the rate of sediment production and movement. An understanding of the many parameters that influence sediment yield is a basic need for managing the State's water resources. The purpose of this report is to describe the magnitude and variability of sediment in Wisconsin streams, to relate sediment yields to the local environment, and to identify areas that need further study. The report is based on sediment data from 44 stream-gaging sites throughout the State. Determination of local areas of erosion and deposition are beyond the scope of the report.

Water resources of Clay, Greene, Craighead, and Poinsett Counties, Arkansas

Water is available in Clay, Greene, Craighead, and Poinsett Counties from ground-water and surface-water sources. However, ground water is more accessible in many places than surface water. Ground water is available from the alluvium, which covers all the area except Crowleys Ridge, and is also available from other formations below the alluvium. Surface water is available from the Black and Cache Rivers west of Crowleys Ridge, and from the St/ Francis and Little Rivers, and from many ditches and laterals east of the ridge. Continuous water supplies are not available from streams on Crowleys Ridge, but additional surface-water supplies could be made available from reservoirs storage on the ridge. Average annual streamflow ranges from 1.2 cfs per sq mi (Cubic feet per second per square mile) in the western part of the four counties to 1.4 cfs per sq mi in the eastern part. Average annual precipitation is about 48 inches. Use of water in the area for agriculture greatly exceeds all other used combined, and progressively greater amounts of water are being used for irrigation. In 1965, 111.4 mgd (million gallons per day) was used for irrigation of other crops. An additional 16.9 mgd was used by industry, municipalities, and others. Of these amounts, 180.1 mgd was ground water and 19.7 mgd was surface water, or a total of 199.8 mgd. More than 80 manufacturing firms, many of which are closely allied to agriculture, use moderate amounts of water, mostly from municipal supplies.

Water resources of the Crow Wing River watershed, central Minnesota

The Crow Wing River, a tributary of the Mississippi River, drains an area of about 3,760 square miles, essentially all of which is covered by glacial deposits. Topography of most of the watershed is slightly- to moderately-undulating and has local relief of up to about 50 feet. The margin of the watershed, particularly the southwestern and northwestern parts, is higher and has local relief often exceeding 150 feet. The higher areas contain numerous lakes and, in the extreme north and east parts of the watershed, are heavily forested.
