About this site

From this vantage point, you can almost see the confluence of Middle Slough and the Cosumnes River—a rare example of a largely undammed river system in California. Rivers and sloughs once flowed more naturally like this before widespread dam construction altered seasonal flood cycles.


Seasonal & Climate Resilience to Observe

Floodplain Inundation – Timing, duration, and extent of seasonal flooding.

Channel Movement – Natural bank erosion, sediment deposition, and channel shifts.

Vegetation Response – Recruitment of native riparian species after high-water events.

Wildlife Use – Fish and bird presence during flood and dry seasons.

Low-Flow Conditions – Water depth and connectivity during drought periods.

Tracking these patterns helps assess how a free-flowing system adapts to extreme rainfall, prolonged drought, and long-term climate variability.

About Cosumnes River Preserve

The Cosumnes River Preserve consists of over  50,000 acres of wildlife habitat and agricultural lands owned by seven land-owning Partners. The Partners include The Nature Conservancy, Bureau of Land Management, California Department of Fish & Wildlife, Sacramento County Regional Parks, Department of Water Resources, Ducks Unlimited, and the California State Lands Commission. The Preserve is centered along the Cosumnes River, its floodplains and riparian habitat. This habitat is buffered by a variety of agricultural operations. The Preserve provides numerous social, economic, and recreational benefits to local communities and to people residing in the larger Sacramento and San Joaquin areas. The habitat supports wildlife, including birds that migrate throughout the Pacific Flyway.
