Pesticide Stewardship Partnership
(PSP)
The Pesticide Stewardship Partnership works with local non regulatory entities to monitor for current use pesticides in surface waters from drift and runoff. DEQ identifies streams with elevated pesticide concentrations or high numbers of detections. Once these areas are identified, Watershed Councils, SWCD and the DEQ collaborate to implement voluntary management practices and follow-up monitoring to determine improvements over time.

The PSP program began sampling in the Wasco Basin in 2010. Over the past 9 monitoring years the Wasco Basin has seen reductions in pesticide detections and number of water quality exceedances. DEQ has 10 different partnerships across the state, and considers the Wasco County Basin partnership a success story. This program has brought awareness to area growers who have willingly implemented pest management practices to protect against spray drift and runoff.

Overall benefits of the PSP program include:
Creating awareness - feedback for pest management practices:
A cost effective alternative to a regulatory approach - proactive, transparent, LOCALLY-DRIVEN and voluntary;
Provides real world data vs. conservative models for decision-making and formulating policy;
And helps ensure that unnecessary regulatory burdens are not placed on pesticide users.

There are three Creeks in Wasco County that are monitored for Pesticides. Mill Creek has two sampling locations. One at Wright Road and the other at the 2nd Street Bridge in The Dalles. Threemile Creek is sampled at Highway 197. Fifteenmile Creek is sampled in two locations as well; Above Seufert Falls (aka Cushing Falls) and in 2017-2018 was sampled at Dufur City Park.
