It actually was a very small article. Here is what it says:
Construction in Portugal on a huge new reservoir, described as Europe's largest man made lake, was set to begin recently with the felling of 1.3 million trees, The Associated Press reported. Cutting all the trees is expected to take about a year.
The resovoir will flood nearly 62,000 acres and extend 50 miles in southeastern Portugal. A 315 foot high dam across the Guadiana River is to be completed next year, after which the reservoir will begin filling. The dam will generate hydroelectric power for the region, and provide water to turn the dry region into a fertile farming and tourist area. Environmentalists say it wil be a disaster.
Nothing about fish or oxygen. Oh well maybe they will update us in a year.
