Tulalip Water Conditions Mostly Unchanged Since 1970s, Study Shows

[Note: The report can be viewed on the Web at .]

Water conditions on and near the Tulalip Indian Reservation, including ground-water levels and streamflow, are statistically much the same as they were in the 1970s, according to study results published in a report by the U.S. Geological Survey (USGS).

Ground water is the primary source of drinking water for the Tulalip Reservation and nearby areas.
The Tulalip Tribes depend on their water and fisheries resources for subsistence, income, and ceremonial and cultural purposes.

In cooperation with the Tulalip Tribes, the USGS studied the water resources of the Reservation and adjacent areas on the Tulalip Plateau in Snohomish County. The USGS study assessed the current state of water resources on the Reservation and compared the results with those of previous studies in the 1970s and 1980s to determine any changes.

Scientists also updated descriptions of the geology and aquifers of the area and prepared new estimates of the area’s water budget (how much of the rainfall that becomes runoff, recharge, or evaporation).

“Results from our study show that ground-water levels have not changed significantly since the 1970s,” said USGS hydrologist Lonna Frans, primary author of the report. “We also found no signficant change in streamflow.”

The report, “Water Resources of the Tulalip Indian Reservation and Adjacent Area, Snohomish County, Washington, 2001-03,” by Lonna M. Frans and David L. Kresch, is published as U.S. Geological Survey Scientific Investigations Report 2004-5166. The report can be viewed on the Web at . Copies can be purchased from the U.S. Geological Survey, Information Services, Box 25286, Federal Center, Denver, CO 80225-0286, telephone 303-202-4200.

The USGS serves the nation by providing reliable scientific information to describe and understand the Earth; minimize loss of life and property from natural disasters; manage water, biological, energy, and mineral resources; and enhance and protect our quality of life.
