To provide information for management efforts to reduce flooding and improve aquatic habitat in the Lower Puyallup River Basin (Puyallup, Carbon and White Rivers), Pierce County and other stakeholders are looking for river-system management options that consider the system's flood-carrying capacity and trends in sedimentation. To assist, the USGS is building a computerized hydraulic model of the lower Puyallup River system that can be used to evaluate different management options, measuring channel cross sections and analyzing changes in them over the past 25 years, and sampling river bed materials for analysis.
