An aerial LiDAR survey of the lower Rio Puerco was conducted in April and July 2005 by Spectrum Mapping, LLC, under contract with the USGS (Contract #14040050). The surveyed reach extends from the NM Highway 6 crossing 55 km downvalley to the old Highway 85 bridge near the USGS streamgage near Bernardo, NM. Survey procedures, equipment and products are described in the Rio Puerco Project Report (Spectrum Mapping, LLC, Aug. 1, 2005), provided with this data set. The survey data include breaklines (shapefiles) used to process the elevation data, bare-earth Digital Terrain Models (DTMs) with 2-m cell size in the ArcGrid format, LAS-formatted files, and the original random xyz data. Results from analyses using these data were published in the following articles: Vincent, K.R., Friedman, J.M., and Griffin, E.R., 2009, Erosional consequence of saltcedar control, Environmental Management, 44, 218-227. doi: 10.1007/s00267-009-9314-8 Griffin, E.R., Smith, J.D., Friedman, J.M., and Vincent, K.R., 2010, Progression of streambank erosion during a large flood, Rio Puerco arroyo, New Mexico, Proceedings of the 2nd Joint Federal Interagency Conference, Las Vegas, NV, June 27 – July 1, 2010, 12 p.
