Summary: The objective of this analysis is to quantify the relative change in river stage at two locations in the lower Susitna River segment between the pre-Project hydrologic condition and the maximum load following OS-1 hydrologic condition. The results of the analysis provide a preliminary assessment of the change in hydraulic conditions in the lower Susitna River segment. The results will also provide a basis for interpreting how hydraulic responses to changes in hydrologic conditions can affect habitats and access to tributaries in the lower Susitna River.

Notes: Chiefly charts and tables.
