Columbia River Bi-State Studies 1990-1996

As the successor to the Lower Columbia River Bi-State Water Quality Program, the Lower Columbia River Estuary Partnership maintains copies of all the original Bi-State Studies.

The Bi-State Water Quality Studies were conducted between 1990 and 1996 and consisted of three phases: 1) gathering existing data so researchers could start with a clear picture of what was already known about the river and its problems; 2) reconnaissance surveys – broad preliminary studies about existing environmental conditions and pollutants of concern; and 3) advanced studies that looked at priority problems based on findings in previous studies.

The Bi-State Program generated over 50 technical reports in six years. A bibliography of the studies and PDF copies of the original reports are now available on the Estuary Partnership web site.

The reports were summarized in “Health of the River 1990-1996: Integrated Technical Report.”

The six-year public-private partnership was jointly administered by the Washington Department of Ecology and the Oregon Department of Environmental Quality and advised by a Bi-State Steering Committee. Steering Committee members came from the many groups that take an active interest in the lower Columbia River: environmentalists, Native American tribes, the pulp and paper industry, private citizens, public ports, local governments, commercial and recreational fishing interests, the Northwest Power Planning Council, and federal agencies dealing with environmental issues. The Bi-State Program was paid for by citizens of Washington and Oregon (1/3 each), the pulp and paper industry (1/6), and public ports (1/6).

PDF links to all the Bi-State Reports are provided below.
