Project Goals and Objectives

BDAs are being used to raise water table levels 1 to 2 feet in order to "irrigate" the dry inset floodplains, and therefore allow restoration planting to occur. It is hoped that eventually the restored hardwoods will shade out the dense non-native plant communities. Long-term morphological changes are restricted in most places on the creek due to the presence of a road.

Structure Construction Elements

BDA design was undertaken specifically to be in line with ODFW fish passage objectives. No individual BDA will have jump-heights greater than 6 inches. BDAs will be installed in stair-stepped complexes to achieve aggregate changes in surface water heights of up to two feet at a BDA complex.
