Surveys have confirmed the survival of both the giant Columbia River spire snail Fluminicola columbiana and the great Columbia River limpet Fisherola nuttalli in the Hanford Reach of the Columbia River, Washington State, as well as other sites in Washington, Oregon, and Idaho. A review of historical collection records suggests that both species exist in still other sites of the Columbia River Basin. At present, there is insufficient information to allow adequate appraisal of either species relative to possible federal or state listing as endangered or threatened species. The results of our studies suggest that additional undiscovered populations of both species exist. There is a relatively good chance that pristine habitat required by spire snails and limpets remains in 37 streams or portions of streams in Washington, Oregon, Idaho, and Montana (British Columbia was considered outside the project scope). For a thorough survey, visits to more than 600 sites will be required. 20 refs., 5 figs., 7 tabs.
