Changes in Management: International Great Lakes
Unprecedented changes in the binational management of the Great Lakes are underway. Problems and programs to solve them increasingly are being considered on an ecosystem (comprehensive,...
Water Treatment Facility Design for a Glacial Lake
The Municipality of Anchorage, Alaska has undertaken a major water supply project, the Eklutna Water Project, to satisfy the growing water demands of Anchorage. The source of raw water,...
Acid Deposition in the Wind River Mountains
National attention has been focused on the discovery of acidified lakes in the Adirondack Mountains of New York and elsewhere in New England. It is commonly believed that the West, in...
Automated Data Collection for Reservoir Regulation
Various regulation changes in the Lake Winnebago basin have been proposed regarding the protection of wetlands and assurance of adequate outflows for water quality. To implement these...
Models for Lake and River Basin Analysis
This tutorial describes basic concepts, purposes and issues of mathematical models for lakes and river basins. Simulation and optimization models are discussed and their structure and...
Optimal Operation of a System of Lakes for Quality and Quantity
A methodology is presented combining simulation and optimization techniques for determining operation strategies for a system of lakes in the presence of quality and quantity constraints....
Great Lakes Water Diversion: Legal Issues
This article deals with state/provincial, regional, federal and international legal issues involved with protecting Great Lakes water. First, the article describes the institutions and...
Multi-Objective Planning: Great Lakes Water Policy Issues
This paper reports upon the development of computer algorithms for multi-objective planning for Great Lakes water policy issues. Sample applications are presented for the control of phosphorus...
Predicting Lake-Chain Quality with Augmentation
Steady-state mass-balance models of lake phosphorus are analyzed with regard to predicting augmentation (or dilution) effects. One form of these models employs a retention coefficient...
Factors Influencing Oxygen Depletion in Green Bay
Dissolved oxygen depletion in the lower Fox River (Wisconsin) and Green Bay (Lake Michigan) have historically been tied to discharges of organic matter from municipal waste treatment plants...
Annual and Seasonal Variations of Phosphorus Loads in the Okanagan River
Results of monitoring of phosphorus loads in the Okanagan River channel linking Okanagan, Skaha and Osoyoos Lakes are described. The southern Okanagan basin is the area where major changes...
Effect of Santa Rosa Lake on Ground Water Flow to the Pecos River, New Mexico
In 1980, Santa Rosa Dam began impounding water on the Pecos River about 7 miles (11 kilometers) north of Santa Rosa, New Mexico, to provide flood control and storage for irrigation. Santa...
Agricultural Nonpoint Source Control Program for Lake Erie
Congress mandated (PL 92-500, Sec. 108d and 108e) that the U. S. Army Corps of Engineers design and develop a program for the rehabilitation and environmental repair of Lake Erie. The...
Low-Cost Stacked Block Revetments for Great Lakes Shores
Two stacked-block revetments, the product of emergency conditions and budget limitations, were constructed at Illinois Beach State Park on Lake Michigan in April 1982. The revetments,...
Large Basin Runoff Forecasting on Small Computers
The Great Lakes Environmental Research Laboratory (GLERL) developed a semiautomatic software package for making deterministic outlooks of basin moisture storage conditions, basin runoff,...
On-Line Hydrologic Simulation of Lake Conroe Reservoir Releases for Downstream Flood Control
Texas A&M Watershed Model (TAMWM) is used to simulate the response of the Lake Conroe watershed following a storm event and to develop an operational policy for flood releases...
Lake Water Level and Sediment Management—Case Studies in Illinois
Estimation of the sedimentation in the lake is based on the soil erosion rates in the watershed, the sediment transport in the stream system, and lake trap efficiency. Erosion rates are...
Assessment of Sediment Problems in Peoria Lake, Illinois
Peoria Lake, located on the Illinois River in Illinois, is the deepest lake in the river valley. Since 1903, the lake has experienced approximately a 31% loss of original storage capacity...
Circulating Water Tunnel Under Lake Ontario
Design and Construction of Terror Lake Dam
Terror Lake Dam is a central feature of the 189 million Terror Lake Hydroelectric Project, located on Kodiak Island Alaska. The dam is a 193-feet (59 m) high concrete-faced zoned rockfill...
