Mackenzie Keith
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.

Preliminary assessment of channel stability and bed-material transport in the Coquille River basin, southwestern Oregon
This report summarizes a preliminary study of bed-material transport, vertical and lateral channel changes, and existing datasets for the Coquille River basin, which encompasses 2,745 km2 (square kilometers) of the southwestern Oregon coast. This study, conducted to inform permitting decisions regarding instream gravel mining, revealed that:The 115.4-km-long study area on the South Fork and mainst

Geomorphic setting, aquatic habitat, and water-quality conditions of the Molalla River, Oregon, 2009-10
This report presents results from a 2009-10 assessment of the lower half of the Molalla River. The report describes the geomorphic setting and processes governing the physical layout of the river channel and evaluates changes in river geometry over the past several decades using analyses of aerial imagery and other quantitative techniques.

Preliminary assessment of channel stability and bed-material transport in the Rogue River basin, southwestern Oregon
This report summarizes a preliminary assessment of bed-material transport, vertical and lateral channel changes, and existing datasets for the Rogue River basin, which encompasses 13,390 square kilometers (km2) along the southwestern Oregon coast. This study, conducted to inform permitting decisions regarding instream gravel mining, revealed that:The Rogue River in its lowermost 178.5 kilometers (

Channel change and bed-material transport in the Umpqua River basin, Oregon
The Umpqua River drains 12,103 square kilometers of western Oregon; with headwaters in the Cascade Range, the river flows through portions of the Klamath Mountains and Oregon Coast Range before entering the Pacific Ocean. Above the head of tide, the Umpqua River, along with its major tributaries, the North and South Umpqua Rivers, flows on a mixed bedrock and alluvium bed, alternating between bedr

Preliminary assessment of channel stability and bed-material transport along Hunter Creek, southwestern Oregon
This preliminary assessment of (1) bed-material transport in the Hunter Creek basin, (2) historical changes in channel condition, and (3) supplementary data needed to inform permitting decisions regarding instream gravel extraction revealed the following: Along the lower 12.4 km (kilometers) of Hunter Creek from its confluence with the Little South Fork Hunter Creek to its mouth, the river has con
