U.S. Army Corps of Engineers Project Opportunity: Willow Creek Reservoir Water Quality Research and Evaluation Studies

Background: The overall goal of this project is to improve water quality conditions in Willow Creek Reservoir for the benefit of the community of Heppner, Oregon, and the surrounding area. The reservoir is characterized by several water quality concerns, including dense cyanobacteria (or blue-green algae) blooms, low dissolved oxygen concentrations, and high nutrient concentrations. Cyanobacteria blooms are known to produce toxins, thereby threatening the aquatic ecosystem and potentially exposing humans and animals to risk of death or chronic illness such as neurodegeneration and liver damage. Each summer, Willow Creek Reservoir post’s health advisories warning users of the potential hazards associated with recreational activities on the lake. Furthermore, fish kills, foul odors and other nuisances are common in Willow Creek Reservoir affecting the community’s ambiance, limiting tourism and recreation on the lake.

This analysis draws upon prior research, readily available data, and new research and data to develop and implement an evaluation program for the restoration of Willow Creek Reservoir and its upper basin. Research results will provide public benefit through enhanced water quality in Willow Creek Reservoir producing public recreation opportunities and natural resource benefits.

Key Dates: Phase I announcement will be open to receive statements of interest continuously until 10:00 a.m., Central Time (CT), 12 June 2026, at which point all statements of interest must be received. If invited to Phase II, full proposal applications will be due at 2:00 Central Time (CT), 09 July 2026.
