The Colorado Division of Water Resources provides a wide range of water related research tools that are available online free of charge. These enable users to retrieve Division of Water Resources’ water data contained within HydroBase; including streamflows, lake levels, water rights, diversion records, calls, etc. Additionally, tools like Map Search (AquaMap) and CDSS Map Viewer provide spatial toolsets to retrieve and analyze information. Research tools may be divided into two classes: Tabular Data Query Tools, which return textual, tabular data; and GIS / Mapping Tools, which use a GIS interface to display and retrieve data.
Index
Additional data and document research assistance is available through our Records Research section.
Bulk HydroBase Data Exporter
This tool allows users to export all Structures, Stations, Well Permits, and Water Rights
(Transactions or Net Amount) for one or more Divisions.
Active Calls
Active administrative calls placed on rivers and streams.
Aquifer Determination Tools (These programs were historically known as SB5 and Dakota)
Tools for estimating the top and bottom aquifer elevations and the thickness of the water yielding sands in the Denver Basin and Dakota/Cheyenne aquifers.
Climate Stations
Evaporation, Temperature, Precipitation and Snow Depth data from the National Oceanic & Atmospheric Adminisration and the Colorado Agricultural Meteorological Network for the state of Colorado.
Groundwater - Other Data
Physical characteristic information collected about wells. Driller log information, geophysical log readings, pumping tests, and volcanic material information (where available).
Other Data
Other Data including Agriculture and Livestock Statistics.
Streamflow Stations
Historic published streamflows and Provisional Administrative gage data from the Division of Water Resources and the USGS.
Surface Water Current Conditions
Real-time satellite streamflow monitoring data from gaging stations maintained by DWR, USGS, and our cooperators. Includes graphing ability and station information.
Structures (Diversion Records)
Information about Diversion Structures, Reservoirs, Non-jurisdictional dams and Jurisdictional dams. Diversion and Reservoir structure information includes irrigated lands, diversion records, and water right information.
Water Rights
Transactional and Net amount water rights; includes links to imaged Water Court documents.
Well Permit Search
Provides detailed reports about well applications and permits with links to related imaged documents. Search by permit number, address, subdivision, or other criteria to pinpoint the well of interest.
A functionality comparison of all GIS / Mapping Tools is available
here.
Map Search (AquaMap)
Interactive map for viewing stream, structure, aquifer, well data, DWR scanned maps, and other layers. Includes section/township/range to UTM and latitude/longitude convertor and Quick Zoom locator.
CDSS Map Viewer
Map based display tool of wells, structures, irrigated acres, and modeling data.
Daily and monthly administration reports for South Platte, Arkansas, and La Plata Rivers are available in our Reports and Publications section.
