New CDSS Online Tool - Stations

The 'Stations' CDSS Online Tool has been rebuilt and is available in beta release. This is the final major CDSS Online Tool to be converted to the modernized web platform. Note that 'Stations' includes structures within Colorado that have telemetry - primarily river gages, large diversions, and reservoir elevations.

The legacy Surface Water Current Conditions page will remain through the 2020 irrigation season. 

Hear more about this new page from the CDSS team at the Water Congress Data and Modeling workshop and at DWR's booth. 

CDSS Web Services Has a New URL and Two New Data Types (Surface Water and Climate Stations)

For an overview of CDSS web services, see here.

The URL for CDSS web services has changed. The arguments are all the same but the server and domain have changed.

Example request for hourly telemetry data

Web Services - TSTool, JavaScript, and cURL examples

Several examples have been created that show how to use web services in several applications. See examples here.

New Division 2 (Arkansas River Basin) Straightline Diagrams

Coming soon. As part of ArkDSS, new Arkansas River and tributary straightline diagrams are being developed. When completed in the following weeks, the new diagrams will be posted on DWR's Laserfiche and on the DWR Division 2 website

TSTool 13.02.00

A new version of TSTool (13.02.00) has been released. This version is required for web services to function since the URL has changed and also includes other minor enhancements and fixes. 

See release notes and documentation here.

To configure web services in TSTool (allows data access from web):
1. Get API key (token) from DWR website

2. Insert API key in HydroBaseWeb.cfg file (located in default install directory C:\CDSS\TSTool-13.02.00\datastores/HydroBaseWeb.cfg)

3. Access HydroBaseWeb Datastore in TSTool 13.02.00:

New HydroBase release 1/2/2020

A new version of HydroBase has been released that includes most timeseries data through October 31, 2018. This release was created to support ArkDSS modeling.

Tutorial to attach locally for use in TSTool.

Lease Fallow Tool update

1) Addition of a “crop stress coefficients” table in the input data page
A stress coefficient table has been added (by year and by crop) to the Lease Fallow Tool (LFT) input data page that can be applied to potential evapo-transpiration (PET) rates (using the “update PET” button). In water use analyses especially in Division 3, aerial photos have been used to identify alfalfa or grass fields that clearly received less than a full water supply. Limiting PET rates can be important for evaluating use of un-metered wells or when there are uncertainties such as with canal losses or ditch proportioning.
2) Correction of a problem with crop rooting depths

3) Update of all data files through year 2018
