Habitat Quantity and Quality Morphological Changes Freshwater-Floodplain Forest Management; Agricultural Practices; Urbanization Diking; Filling; Riparian Degradation; Wetland Loss Juveniles Channel straightening, ditching, and diking have reduced floodplain connectivity and function.
Habitat Quantity and Quality Small-Scale Structural Complexity; Morphological Changes Freshwater-Riparian Agricultural Practices; Urbanization Riparian Degradation; Impervious Surfaces Juveniles The riparian habitat in some of the lower reaches in the basin has been affected by recreation, residential, agricultural, and municipal activities. Agricultural and residential development activities have altered or disturbed some riparian habitat areas.
Habitat Quantity and Quality Small-Scale Structural Complexity; Morphological Changes Freshwater-Instream Agricultural Practices; Forest Management Riparian Degradation; Wood/Structure Removal Juveniles Many stream reaches surveyed within the Sandy watershed are considered to be moderate to undesirable for attributes such as large wood density and pool frequency.
Instantaneous Mortality Anthropogenic Mortality -- Fishery Management Harvest Adults Coho are subject to both ocean and freshwater harvest.
Sediment Conditions Increased Sediment Quantity Freshwater-Instream Forest Management; Agricultural Practices; Urbanization Bank Destabilization; Impervious Surfaces (Road Density); Riparian Degradation Juveniles While there is a high natural background level of fine sediment in the Sandy River, management practices on both private and federal lands increase fine sediment routing.
Water Quality Temperature -- Agricultural Practices; Forest Management; Urbanization Water: Temperature and Gas Alteration Juveniles Water temperatures in some reaches of the Sandy River Basin exceed state temperature water quality standards
Water Quantity Decreased Water Quantity; Increased Water Quantity; Altered Flow Timing -- Dam or Hydropower Facility Management Water: Runoff Coefficient Alteration; Water: Hydrologic Cycle Alteration Juveniles Hydrosystem operations affect the hydrograph and nutrient input into the estuary.

Hydrosystem operations affect the hydrograph and nutrient input into the estuary.
