Fish and hydroelectric dams are striving to coexist across the country. With conservation groups as well as state and federal agencies pressing for severe controls on water releases, hydropower production has been cut substantially in many cases. At the same time, dam operators have undertaken some sophisticated construction programs to meet the challenge. To date, many strategies employed on the Columbia and Snake Rivers have been both costly and ineffective. The Army Corps of Engineers is trying to address its problems partly with extensive model studies. But, they have found that "the more you learn, the more complicated it gets." Together the failures of the Corps, as well as other federal agencies have caused the power utilities to call for reductions in spending for all fish programs, which they say are ineffective.
