The first is Historical floods and geomorphic change in the lower Little Colorado River during the late 19th to early 21st centuries (usgs.gov) by Joel Unema and others. This report draws from a variety of data to construct a peak-flow history of the lower Little Colorado River. Included is an analysis of reductions in peak flow magnitudes and frequency of larger floods since the late 1800s and the associated relations to geomorphic change.
The second report is Groundwater and surface-water data from the C-aquifer monitoring program, Northeastern Arizona, 2012–2019 by Casey Jones and Michael Robinson. This report describes historical and recent data (2012-2019) collected to characterize the hydrologic status and trends in the Coconino (C-aquifer) of northern Arizona. Included are groundwater data as well as surface-water discharge and water quality field parameters.
The third report is Preliminary assessment of carbon and nitrogen sequestration potential of wildfire-derived sediments stored by erosion control structures in forest ecosystems, southwest USA (usgs.gov), a journal article by James Callegary and others. This study examines the potential for sequestration of wildfire-derived carbon and nitrogen in sediments captured by in-stream erosion-control structures.
