This report gives a detailed treatment of the geological, hydrological, and engineering factors affecting 
erosion and sedimentation in the upper Cañon Largo watershed on the southern Jicarilla Apache Nation, 
New Mexico. We summarize previous studies of geology and hydrology and provide new detail on stream 
dynamics, sediment transport, and rates of erosion and sedimentation. Two new maps are complements to and 
were produced concurrently with this report: the Geologic Map of the Cañon Largo Watershed on the 
Jicarilla Apache Nation, Rio Arriba and Sandoval Counties, New Mexico, which presents detailed surficial 
geologic mapping and descriptions at the 1:50,000 scale, and the Erosion and Sedimentation Hazard Map of 
the Cañon Largo Watershed on the Jicarilla Apache Nation, Rio Arriba and Sandoval Counties, New Mexico, 
which displays the computed level of risks associated with the potential for an erosion or sedimentation 
event, also at the 1:50,000 scale. Each of these maps has its own associated report.
