Cosumnes River Preserve Description
Within the Sacramento/San Joaquin basin, the Cosumnes
River constitutes one of the finest natural laboratories for the
study of watershed-scale physical and biological
systems. At 1,265 sq. miles, the Cosumnes River basin is relatively
small, making it appropriate and accessible for detailed study.
With limited urbanization, and no significant dams, its hydrologic
system is largely intact, affording a unique opportunity for monitoring
and evaluation of the impacts
of land use change on ecosystem and watershed function. Forming
a natural, uninterrupted link between the Sierra Nevada and the
Bay-Delta Estuary, this river has been the centerpiece of an ambitious
public/private restoration effort. For the past decade, The Nature
Conservancy has been acquiring and managing Cosumnes lands, including
extensive floodplain tracts containing native riparian oak woodland.
