Coeur d'Alene Lake Water Budget

Development around Coeur d'Alene Lake has accelerated over the past 25 years. Commercial and residential development adjacent to the lake plus demands for irrigation, recreation, and hydropower raise concerns about the potential for declining lake levels.

A comprehensive lake water budget helps resource managers determine the possible effects of growth on lake levels.

Much of this material has been discharged directly to or washed into...

Douglas-fir trees topped to create snags for wildlife habitat

Snags provide habitat for a wide range of organisms from cavity-nesting birds to insects, and are critical for maintaining forest biodiversity. Resource managers can create snags by topping trees to mitigate loss of snags to timber harvest, but information regarding changes in habitat for snag-dependent wildlife over time as created snags decay is lacking. Oregon State
