Foundation Evaluation of Barkley Dam for Seismic Analysis
An in-situ site investigation was performed at Barkley Dam, KY to gather essential information on the stratigraphy and nature of the foundation soils. From this information the site was...
Three Dimensional Modeling of Ground Water Flow and Temperatures at Bonneville Dam, Oregon
Harvest Facility Protects and Improves Fishery
By constructing a trap and transfer/harvest facility to control anadromous fish migration, the trout fishery on the Boardman River was protected and the salmon fishery was improved. The...
The Gloryhole Approach to Increasing Dissolved Oxygen Content
Deep intakes at hydroelectric dams in southern states withdraw water that is oxygen deficient during summer months when reservoirs become stratified. The 'Gloryhole'...
Glen Canyon Hydropower vs. The Grand Canyon (The Conflict of Basic Values)
Competing for the scarce resources of our future is the byword of the 1990's. For the last century and more, the United States has been in the position of always having more...
Relative Survival of Juvenile Chinook Salmon Through Bonneville Dam on the Columbia River
Preliminary results of a multiple year study indicate that juvenile chinook salmon passing through the juvenile bypass system at Bonneville Dam second powerhouse during the summer have...

The PEC Headworks Project—A Cooperative Hydropower Development
The PEC Headworks Project is a single-unit hydroelectric facility located at the headworks of the Potholes East Canal at O'Sullivan Dam on the Potholes reservoir near Moses...
Measurements of Time Lag in Concrete Gravity Dam Foundations
Uplift measurements from eight large concrete gravity dams show that the time lag between an increase in headwater level and a corresponding increase in uplift pressure is insignificant....
Foundation Investigations of Concrete Dams
This paper discusses a series of foundation investigations conducted on concrete dams by Pacific Gas and Electric Company. The paper focuses on investigative techniques, equipment, appropriate...
Assessment of Changes at Glen Canyon Dam
This paper describes the complexity associated with the assessment of financial impacts of proposed and actual short-term restrictions at Glen Canyon Dam. The reasons for these restrictions...
Case Study: Steele Creek Dam Safety Analysis, Bristol, Tennessee
Steele Creek Dam creates a small recreational park lake before discharging into Beaver Creek a few hundred yards below the dam. Existing homes and trailers downstream from this junction...
Risk Analysis Applications for Dam Safety
Dam safety modifications are intended either to reduce the likelihood of the adverse consequences of dam failure or the magnitude of adverse consequences. For instance, widening a spillway...
Examples of Risk Assessment in Dam Safety Decision Making
Three examples of risk-based dam safety evaluations performed for dam users or operators are summarized. These studies were conducted by major U.S. engineering firms and involved experienced...
The Stabilization of Minidoka Powerplant and Dam
The rehabilitation of structures can pose numerous challenges to the engineer. The structure historical preservation, the benefit cost ratio of the rehabilitation, and the stability of...
Stability Analysis of Gravity Dam Foundations with Horizontal Seams
Determination of the overall factor of safety against sliding is an important aspect in concrete dam design. Limit equilibrium methods have serious limitations. A method for determining...
