Public Participation Opportunities

Groundwater Study Work Plan and Public Participation Plan

The Cooperating Agencies (Oregon Water Resources Department, Washington State Department of Ecology, and the US Geological Survey) have finalized the Groundwater Study Work Plan and developed a draft of the Public Participation Plan. The Cooperating Agencies invite your review and feedback on the following documents by March 25:

You can provide feedback any one of the following three ways:

  1. Preferred: Fill out this short survey.
  2. Email your feedback to
  3. Call Harmony Burright (971) 301-0718 to discuss your feedback.

Feedback on the Final Groundwater Study Work Plan will be used by the Cooperating Agencies to guide how they execute the Work Plan. No modifications will be made to the Work Plan document itself. The Cooperating Agencies will consider and respond to feedback offered and will include a description of how feedback is being used to guide agency activities or approaches. Key question to consider: Does the Work Plan propose to tackle the groundwater question(s) that are most important to you?

Feedback on the Draft Public Participation Plan will be used by the Cooperating Agencies to finalize planned public participation and communication activities for the duration of the groundwater study. Your feedback may lead to modifications to the plan and the proposed activities. Any modifications will have to consider schedule, budget, and resource constraints. Key question to consider: Do the planned public participation and communication activities provide adequate opportunities to be informed and involved as the study progresses?
