  Glen Canyon Dam -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-10-18)
The dam is 1,560 feet long along its crest, 300 feet thick at the base and 25 feet thick at the top.
Although the dam was not dedicated until 1966, it was able to begin blocking the flow of the river in 1963.
Owing to this dam, there had not been the periodic flooding that would wash away and renew sand banks along that portion of the Colorado River that transited the (The enormous gorge of the Colorado River in northern Arizona) Grand Canyon.

Juvenile salmon tend to be in the upper 30 to 35 feetof the water mass and the direction and velocity of its movement direct the movements of the juveniles.
It was not until development was well underway that studies demonstrated that juveniles passing through the turbines experienced substantial levels of mortality, in the range of 11% to 15% in the first studies.
At Wanapum Dam it was found that the prototype surface flow bypass was not sufficiently effective in collecting fish, but that it was effective in diverting a high percentage of the fish away from the turbine intakes and toward the spillway.

The system, called a limestone diversion well, involved construction of a large concrete cylinder into which water from the stream was diverted by piping from an upstream dam.
Slightly larger fragments were carried from the well with the discharge, coating the stream bottom below the outflow with a fine limestone sediment that continued to neutralize acid in the stream itself.
Twin lines of 8-inch PVC pipe were laid on the ground surface from dam to the wells, spillways were installed to carry water from the wells back into the stream.

 Work on Frederica to hit high gear with wells, coffer dam   (Site not responding. Last check: 2007-10-18)
The wells are necessary to drop the water table below the fractured sewer, which lies 31 feet below Frederica Street.
Digging the "de-watering" wells will take about 10 days, Hawes said, while pile-driving equipment will be used to push the sheet pilings down 55 feet.
Building the coffer dam will be a slow process because lateral I-beams will have to be welded in place inside it to prevent the trench from collapsing.

 Pressure Relief Wells for Earth-fill Dam
The dam was constructed by the NSW Public Works Department in the early 1960s; neither a foundation cut-off nor a chimney drain were incorporated in the design.
Shortly after the dam was filled, artesian groundwater pressure above ground level was observed at the downstream toe of the main embankment.
A new system of pressure relief wells, constructed from corrosion resistant materials and equipped with an integral cleaning system utilizing hydroxyacetic acid as the main biocidal and cleaning agent, operated by gas pressure, was designed.

 DJC.COM: Engineers study Columbia dams for alternatives to breaching, provided by Seattle Daily Journal of Commerce
There is consensus that Wells Dam, upriver from Rocky Reach, has the best design for fish passage on the Columbia -- by default because physcial constraints dictated the design at this facility.
At Wells, juvenile salmon pass directly over the dam without having to be diverted to another route for passage.
Also, Wells' generator turbines operate parallel, instead of perpendicular, to the flow of the river and the turbine intakes are below the level where fish pass through spillway gates.

Wells implemented its surface flow attraction system for juvenile fish on April 1 this year, about two weeks ahead of schedule, in anticipation of poor runs of spring chinook.
Wells' surface attraction system is the model for the prototype bypass systems being tested at Rocky Reach and Wanapum Dams.
The geography of the Wells site led designers to put the dam's spillway on top the turbine generators, rather than alongside; that means the strongest currents are in the top portion of the flow, where the fish congregate--sending most of the migrating juveniles through Wells' spillways rather than its turbines.

 Columbia River sees big salmon runs this summer   (Site not responding. Last check: 2007-10-18)
Last year set a modern-day record, with more than 127,000 adult summer chinook counted at the Bonneville Dam, which is closest to the mouth of the 1,200-mile-long river; and almost 63,000 reaching the Wells Dam, farther upstream.
Migration of summer chinook is still under way, but the numbers suggest a good return this year as well, with more than 112,000 adult summer chinook at Bonneville Dam; and almost 26,000 at Wells Dam.
One of the worst years for fish in recent memory was 1995, when just over 15,000 adult summer chinook made it to Bonneville Dam and fewer than 2,800 went as far upriver as the Wells Dam.
