Discharge rates in the Rio Pecos Headwaters
I downloaded and displayed the national hydrology units for the United States, and created a new layer for the Rio Grande, region 13. Within that layer I created a new layer for the Rio Pecos and added streams and dams. From those layers I created a new layer for the streams, dams, and hydrologic units for the Rio Pecos headwaters (HUC 1306001) and the Pintada Arroyo (HUC 1306002). To do this I used both the Select by Attribute function, as well as the selection tool.
I then downloaded the spatial data and the annual discharge data for the stream gauges in the 1306001 and 1306002 HUC from the USGS website. I was able to join those tables and display the data for the discharge at each station. I activated the time viewing and changed the speed of the player to display the change in discharge from 1907 to 2011. I tried to export it as a video, but ArcMap crashed every time I tried to export it. In the end I made a map displaying the average daily discharge for 2010, since that is where the player ended. I tried labeling the gauge sites by name, but they were really long, so I labeled them by site number, this way there is enough information in the map to retrieve the names if someone wanted to. I also included the names of the dams and the location of Santa Fe for reference.
