Geomorphic changes on the Mississippi River flood plain at Miller City, Illinois, as a result of the flood of 1993
Robert B. Jacobson, Kevin A. Oberg
1997, Circular 1120-J
During the 1993 floods on the upper Mississippi and Missouri rivers, the most dramatic changes to floodplains occurred at levee-break complexes where large discharges were concentrated through narrow breaks in levees. Scour and deposition associated with levee breaks adversely affected large areas of formerly productive bottomland. This case study of...

Nitrogen and phosphorus loading from drained wetlands adjacent to Upper Klamath and Agency lakes, Oregon
Daniel T. Snyder, Jennifer L. Morace
1997, Water-Resources Investigations Report 97-4059
Upper Klamath Lake and the connecting Agency Lake constitute a large, shallow lake in south-central Oregon that the historical record indicates has likely been eutrophic since its discovery by non-Native Americans. In recent decades, however, the lake has had annual occurrences of near-monoculture blooms of the blue-green alga Aphanizomenon flos-aquae...
Hydraulic properties and ground-water flow in the St Peter-Prairie du Chien-Jordan aquifer, Rochester area, southeastern Minnesota
R. J. Lindgren
1997, Water-Resources Investigations Report 97-4015
The hydraulic properties were updated and their effects on ground-water flow in the St. Peter-Prairie du Chien-Jordan aquifer in the Rochester area in southeastern Minnesota were evaluated, using new information compiled since a study by Delin (1990). Since 1988, new information on the hydrogeology of the ground-water system in the...

1997, Water-Resources Investigations Report 96-4223
A water-quality assessment of the upper Illinois River Basin (10,949 square miles) was conducted during water years 1987-91. This assessment involved interpretation of available data; 4 years of intensive data collection, including monthly sample collection at eight fixed-monitoring stations in the basin; and synoptic studies of selected water-quality constituents at...

On June 15, 1991, Mount Pinatubo in the Philippines exploded in the second largest volcanic eruption on Earth this century. This eruption deposited more than 1 cubic mile (5 cubic kilometers) of volcanic ash and rock fragments on the volcano's slopes. Within hours, heavy rains began to wash this material...
