When Fern Ridge Lake levels are low the Long Tom River can be seen meandering through the reservoir. Check out the USGS water elevation gage at Fern Ridge Lake Near Elmira, OR - 14168000.

Mackenzie Keith is a Hydrologist at the USGS Oregon Water Science Center.
Mackenzie joined the Oregon Water Science Center in 2009 as a hydrologist on the Geomorphology Team. Her main research focuses on documenting and understanding recent and historical physical changes to rivers to inform restoration and management decisions. Current projects include characterizing the geomorphic responses of dam removal on the Sandy River, mapping the Willamette River floodplain geomorphology, characterizing the coupled upstream-downstream geomorphic responses to deep reservoir drawdowns at Fall Creek Lake, and developing a geomorphic framework to inform erosion and deposition processes within Willamette Valley reservoirs.
Science and Products
Fern Ridge Geomorphology
The USGS, in cooperation with the U.S. Army Corps of Engineers (USACE), is conducting targeted research to better understand geomorphic conditions and processes within the reservoir at Fern Ridge Lake, near Eugene, Oregon, so that managers have the information to support dam operations and other actions that will aid in the preservation and management of cultural sites.
Willamette FIP Effectiveness Monitoring Framework
The goal of this project is to develop an effectiveness monitoring framework that can be used to inform monitoring and data collection for the Willamette River Focused Investment Partnership (WFIP) Effectiveness Monitoring Program. The USGS is developing this monitoring framework in collaboration with the Benton Soil and Water Conservation District (BSWCD), Bonneville Environmental Foundation (BEF...
Geomorphic Response to Fall Creek Lake Drawdowns
The USGS has been documenting the geomorphic response to the annual Fall Creek Lake drawdown since 2011.
A Thermal Mosaic for the Willamette River
The U.S. Army Corps of Engineers operates 12 dams in the Willamette River Basin. The dams alter natural temperature and hydrologic regimes. Unnatural water temperatures can negatively impact all life stages of salmonid fish species. Water temperature in the mainstem Willamette River regularly exceeds the standard of 18.0 °C (64.4 °F) designated for salmon and trout rearing and migration for mid...
Marmot Dam Removal
Marmot Dam on the Sandy River was removed in 2007 as part of decommissioning of Portland General Electric’s Bull Run Hydroelectric Project. Removal of the 15-meter-tall dam would allow the Sandy River to flow freely for the first time in nearly 100 years and make upstream habitat more accessible to anadromous fish.

Fall Creek drawdown
Drawdown of Fall Creek Lake result in lake levels being lowered to the elevation near the historical, pre-dam streambed.
