In the Kenai Peninsula Lowlands, Alaska, groundwater discharge comprises ~70% of annual streamflow, playing a key role in modulating flow and temperature in salmon-bearing streams. Before discharging to streams, groundwater flowpaths are often intersected by landscape elements such as peatlands, floodplains, sloughs and oxbows, and lakes. These landscape elements can perform hydrologic functions including lag (e.g., storage), sink (e.g., groundwater recharge), and source (e.g., flow generation), which in turn influence the chemical and biological characteristics of downstream waters. In this region, approximately 40% of mapped surface and subsurface flowpaths intersect peatlands, highlighting their potential importance in conditioning groundwater prior to discharging to streams. The Anchor River is a groundwater-influenced system draining peatland-dominated landscapes and supports one of the largest salmon fisheries in the region. To characterize peatland hydrologic functions, we deployed continuously recording specific conductance loggers in monitoring wells on a flowpath from a hillslope, through a peatland, through another hillslope, through a slough and oxbow, and along a river transect to the estuary, with simultaneous river discharge measurements. We used specific conductance as a conservative tracer to distinguish between precipitation and groundwater sources to flow and to infer relative residence times along the flowpath. Preliminary results from May – October 2025 show distinct spatial and temporal patterns in specific conductance, with measurements distinguishing between shallow, seasonally variable groundwater and deeper, stable groundwater throughout the flowpath, including within the peatland. River measurements reflect a mixture of these shallow and deep groundwater sources. Together, these patterns indicate that peatlands perform multiple hydrologic functions, including storing water, contributing to downslope groundwater discharge, and facilitating localized mixing of groundwater before discharging to the stream. These hydrologic and chemical measurements intersect an existing salmon monitoring weir and rotary screw trap that record both adult salmon upstream migration and juvenile outmigration. This work provides an initial framework for characterizing peatland-stream hydrologic connectivity and establishes a foundation for the next step of the project to develop a statistical model with local management that links water quality and discharge to observed salmon migration patterns.
