     "text": "Management of brook trout fisheries requires monitoring within headwater streams, and this could benefit from geophysical analysis of groundwater dynamics within small catchments. Monitoring for the onset of dewatering could be accomplished through imagery analysis such as the Flow Photo Explorer, and locations with shallow depth to bedrock could serve as an early-warning system for deeper aquifers elsewhere."

     "text": "Recent USGS studies provide new insights on the geophysical basis of stream dewatering during drought and the ecological consequences for brook trout populations in Shenandoah National Park, Virginia. The first study used passive seismic instrumentation to evaluate the depth to bedrock along eight mountain stream corridors, and differences in bedrock depth were associated with the onset of dewatering in streams and fine scale patterns of wet and dry patches in less resilient subcatchments (Briggs et al. 2022). The second study evaluated brook trout abundance data collected in the same study area over a 10-year period (2012-2021) and found evidence for population fragmentation associated with periodic dewatering that was not well informed by downstream streamflow records (Hitt et al. 2024)."

     "text": "Stream ecosystems support vital resources that may be jeopardized by climate change and climate stressors such as drought. In the headwaters of the Chesapeake Bay, native brook trout (Salvelinus fontinalis) are recognized as a high priority for conservation and restoration by Chesapeake Bay Program partners, and USGS research efforts are underway to provide science to address these needs. Prior research has demonstrated the importance of stream-groundwater connectivity in promoting thermal resiliency to air temperature in streams. However, the role of role of groundwater for stream ecosystems during drought is poorly understood, yet the frequency and magnitude of drought events are expected to increase due to climate change, and this necessitates new hydroecological research."
