Groundwater discharge sustains critical late-summer streamflows and buffers temperature in the South Fork Nooksack River

Scientific investigations report · 2014

Key Findings

01Groundwater plays a significant role in maintaining late-summer streamflows in the South Fork Nooksack River.
02Groundwater discharge contributes to buffering stream temperatures, creating cold-water refugia essential for threatened salmonids.
03The primary aquifer interacting with the river is within unconsolidated glacial outwash and alluvial sediments, overlying bedrock and finer-grained glaciomarine/glaciolacustrine sediments.

Application

Design takeaway

How to apply

When designing water management plans, consider conducting detailed hydrogeological surveys to map groundwater-surface water interactions and their ecological significance.

Project actions

01When researching water bodies, look for studies that examine the connection between underground water and the water you can see in rivers or lakes.
02Consider how your design might affect the flow or temperature of nearby water sources, both above and below ground.

Method & Evidence

AimTo characterize the groundwater-flow system and its interaction with surface-water features in the South Fork Nooksack River Basin to inform water resource management and ecological restoration efforts.

MethodHydrogeologic framework development and synoptic streamflow measurements.

ProcedureA hydrogeologic framework was established using mapped geologic units and well logs. Groundwater flow directions were interpreted from groundwater level measurements, and groundwater seepage gains and losses to the river were calculated from streamflow measurements. Seasonal groundwater level fluctuations were monitored over a water year.

ContextRiver basin hydrology and water resource management

Variables

IVHydrogeologic characteristics (e.g., aquifer properties, geological units)

DVStreamflow, stream temperature, groundwater levels

CVSeason (late summer, monthly measurements), river basin location

Strengths & Limitations

Strengths

+Comprehensive hydrogeologic framework development.
+Integration of field measurements for groundwater and surface water.

Limitations

The specific geological conditions of the Nooksack River Basin might not apply to all locations.

Reliability & validity

The study's reliance on mapped geologic units and well logs provides a robust framework, while synoptic streamflow measurements offer direct evidence of interactions. However, the interpretation of flow directions from limited measurements could introduce some uncertainty.

Think critically

How might changes in land use (e.g., urbanization, agriculture) in a river basin impact the groundwater-surface water interactions described in this study, and what are the potential consequences for aquatic life?

Design Principles

"Sustainably manage water resources by understanding and protecting the interconnectedness of groundwater and surface water systems."

This research highlights the vital role of groundwater in sustaining aquatic ecosystems during dry periods. Designers and engineers involved in water management, infrastructure development, or environmental restoration need to consider these subsurface dynamics to ensure the long-term viability of river systems and the species they support.

What This Means for Your Design

This study shows that water underground (groundwater) is really important for keeping rivers healthy, especially for fish like salmon, by making sure there's enough water and it stays cool in the summer.
