Verde River water budget

Riparian-aquatic
Verde River
Abstract

This map represents a combination of several data sources displayed geographically in order to better understand the influences on water resources in this important region.

The fundamental data set is a conceptual water budget prepared by the Arizona Department of Water Resources. This provides estimates of water inflows and outflows or removals from the system, broken out by discrete segments of the basin. Those values are graphically displayed here with proportional symbols placed within the appropriate subbasin or river reach. Those placements are diagrammatic and do not indicate precise locations of discharge or use.

Also mapped are land uses that have implications for water supply. These were derived from U.S. Geological Survey data on land cover, augmented with BLM data on housing density information from aerial photographs. Additional data displayed include perennial streams, major springs, and evaporative losses from Horseshoe and Bartlett reservoirs.

Every June groups of volunteers walk the entire 170 mile length of the San Pedro River and record where it is wet and where it is dry during the hottest, driest time of the year. Twenty years’ worth of data on summertime surface flows in the San Pedro River within the San Pedro Riparian National C[…]

Forest density and snowpack stability regulate root zone water stress and percolation differently at two sites with contrasting ephemeral vs. stable seasonal snowpacks
Much of the western United States depends on high elevation snowpack in forested watersheds for water supply, wildlife habitat, and recreation in both adjacent and downstream communities. The forest-snow-water relationship is well studied in areas with stable – that is, cold – seasonal s[…]
