1. Overview of the Tualatin Urban Beaver Dam Study

Populations of North American beaver (Castor canadensis) have increased in recent years due to decreased trapping, habitat restoration, and recognition of their importance as a keystone species in stream ecosystems (Pollock and others, 2017). Previous studies have shown that beaver dams and associated ponds can change channel morphology, trap sediment (and

2. Beaver Dam Inventory and Beaver Dam Capacity Estimates

Beavers and their dams can substantially change the storage and movement of water through a stream reach. The magnitude of this change is, in part, a function of the number and type of dams plus stream characteristics. If beaver activity is to be considered as a flow-management aid, then understanding the locations where beavers currently are building dams and the

3. Hydraulic Effects of Beaver Dams

Beaver dams and ponds fundamentally alter how water moves through a stream reach. Semi-porous dams can impound water, leading to backwatering, floodplain inundation, and overall changes in wetted area, depth, and velocity.

For this part of the study, USGS:

USGS-PSU Grant Proposal Information

USGS - PSU Partnership (UPP) 2019 Request for Proposals.

The USGS-PSU Partnership (UPP) is a cooperative agreement between Portland State University and the U.S. Geological Survey’s Oregon Water Science Center (ORWSC). The purpose of this partnership is to further our understanding of water science by supporting joint research; facilitating the sharing of data,

4. Effects of Beaver Activity on Water Quality

Beaver dams and ponds alter the movement and storage of water as well as the water quality in a stream reach. To date, little work has been done to quantify the effects of beaver activity on water quality in urban streams.

In this part of the Tualatin beaver study, USGS assessed changes in water quality along beaver-affected reaches of Fanno Creek at Greenway Park

5. Effects of Beaver Dams on Sediment Transport

Beaver dams and associated ponding affect sediment transport and trapping by pushing water onto the floodplain and decreasing stream velocity, allowing for increased sediment deposition.

For this part of the Tualatin beaver study, USGS assessed changes in sediment dynamics along beaver-affected reaches of Fanno Creek at Greenway Park and Bronson Creek. Here, we
