Basin Hydrology: Modeling Colorado River Stream Flows

Navigating the dash Pan and zoom the map to a location of your interest, then click on a model node to produce additional hydrologic summary figures below. Modeled flow nodes are sized proportional to stream flow at that location.

Hydrologic Alteration: Modeling Colorado River Stream Flows

Navigating the dash Pan and zoom the map to a location of interest then click on a model node to produce additional information below. Map points represent various metrics of hydrologic alteration at StateMod modeled flow nodes. Nodes are sized and colored proportionally to the amount of hydrologic alteration at that location.

Water Quality in the Headwaters Region

Navigating the dash This dashboard is intended for high-level exploration of water quality conditions. It should not be utilized to make legal determinations of stream impairment. Select an individual analyte in the drop down menus to the right then pan and zoom the map to a location of interest. Click on the monitoring site to produce summary graphs. Use the additional filters to help filter analytes. Add a reference line for comparison if you know your local water quality standards.

Stream Regulatory Status in the Headwaters Region

Navigating the dash Pan and zoom the map to your stream of interest. When zoomed in, select a stream segment and display summary information on regulatory status. Maps may update slowly due to the large underlying datasets, navigate slowly for best results.

Water Use in the Headwaters Region

Navigating the dash Pan and zoom the maps to a location of interest, then click on a model node to produce additional summary figures below. Modeled flow nodes are sized proportionally to the diverted or consumed amount at that location. Maps may update slowly due to the large underlying datasets, navigate slowly for best results.

Colorado Headwaters Studies and Datasets Library

Using this page Select a study or dataset in the scroll table to display summary information and links to the complete document (when available). Filter studies results at a variety of geographic, date, and topic levels using the drop down menus.
