We often use this site to respond to questions raised in the community. Nestle Waters works to answer questions and correct the record when appropriate.
Recently several inaccurate statements were published relating to issues about our proposed new bottled water facility in Cascade Locks. As regular visitors to this site will note, decisions have yet to be made regarding whether the facility will be built. Regardless, we hope you find this information helpful.
Claim According to a
USGS study, ground water levels are falling across the entire Columbia Plateau.
Facts The USGS study compared water levels between 1984 and 2009 in 470 wells drilled in a variety of geologic areas across the Columbia Plateau.
According to the report, “Small to moderate groundwater-level declines were measured in most wells, although declines greater than 100 feet and as great as 300 feet were measured in many wells. Essentially unchanged groundwater levels were measured in other wells.”
In fact, the one well measured in Hood River - the closest one to Cascade Locks - with data from 25 years ago, showed no change in water level between 1984 and 2009. (Well # 454106121342401, USGS Report Appendix A).
However, the water sources in the USGS study differ from those serving Cascade Locks. There are major climate and geologic differences at play.
Climate differences – It rains more in Cascade Locks – a lot more
Pendleton: 13 inches of rain a year source: Pendleton Chamber of Commerce
Cascade Locks: 70 inches of rain a year source: city of Cascade Locks
Water source differences - Aquifers recharge faster in Cascade LocksEastern Columbia Plateau Aquifers between layers of solid basalt.
Deep aquifer system. The average well depth for the USGS study was 460 feet.
Long recharge time, several thousand to 10,000 years. (Vlassopoulos, 2009)
Water use declining since 1930's due to historic overuse.
Cascade LocksPermeable soil with large rocks and boulders from landslides and floods.
Comparably shallow aquifers: 100 feet at city well field (source: city of Cascade Locks well logs). Less than 50 feet at Oxbow Springs (source: visual observation)
Six to 12 months recharge from rainfall at city well field and Oxbow Springs, based on seasonal observations, ODFW records beginning in 1969.
Oxbow Springs, stable flow over time, as demonstrated by ODFW records beginning in 1969.
City records indicate stable water levels that follow trends in Columbia River stage.
