INVASIVE SPECIES -- An Independent Economic Advisory Board update released last week indicates that the money spent – an estimated $5 million per year from a variety of sources -- in attempts to ward off an invasion of non-native zebra and quagga mussels into the Columbia River basin is money well spent.
However, the report acknowledges there's still a probability the damaging species will eventually get into the Columbia and Snake River systems and raise havoc for irrigators, municipalities and hydropower managers, not to mention boaters and anglers.
