The Upper Colorado Endangered Fish Recovery Program coordinates numerous activities intended to benefit four listed species endemic to the warm water mainstem river and tributary reaches of the Colorado River Basin. These activities include mechanical removal of nonnative fish, floodplain wetland management, propagation and stocking of some listed species, listed species targeted research and monitoring and water management. While data may be accessed through freedom of information pathways (FOIA for federal, GRAMA for state of Utah and CORA for state of Colorado) we prefer to make what we can openly available and have developed an information request process for more granular data access. Please read the Recovery Program Data Use Commitment before accessing our data resources!

Data access

Regardless of access pattern, you are responsible for investigating and understanding the context of the data you request. We compile data from over 30 years that spans hundreds of unique studies. There is no assumption that the data you receive has any consistency in collection methods! There is alos no assumption that the data is entirelly correct. We have a robust QC process presently, however, older data, especially pre 2015 is more affected by incompleteness, duplication and bad values than present data.

  • We strongly suggest you understand the collection methods of ALL studies contained in your dataset request export prior to running any analyses. Information on recent study methods are contained in annual reports and are available on our website

  • If you are considering using the data in a publication or for wide distribution we urge you to contact the office conducting the field work to discuss nuances of data collection or study design which may not be apparent from the annual reports.

Tagged Fish Encounter Data

The program stores much of its species encounter data in its self-service data system the Species Tagging, Research and Monitoring System (STReaMS). This data source spans 40 years of fish encounters, predominantly listed species, however we do posses limited Three Species encounter data. Aggregated species occurrence data is available through the web portal and is a great starting place for any data request. You will need to create an account to access data resources. The site has numerous filters to assist you in creating refined queries. If you require more granular encounter location data, you will need to complete a data request (see below)

Non Tagged Fish Encounter Data

We do manage non tagged fish encounter data. This resource spans only the past 10 years, but contains encounter data including biometric data for numerous species. This data is only available through the data request process.

Other Sampling Data

We manage other fisheries sampling data including effort, habitat metrics, water quality and more. These data are only available through the data request process.

Thermograph data

The Upper Colorado River Recovery Program works with partner agencies to maintain temperature sensors throughout the basin within both mainstem and tributary rivers. Daily mean and median values from all monitored sites (2021 – present) are available on our website


The Data Request Process

If after reading the documentation above, you determine that a data request is necessary to meet your needs.

  1. Read and accept the Recovery Program Data Use Commitment
  2. Contemplate your data needs and intended use and describe exactly what you are looking for. The more specific a data request is, the more quickly it can be fulfilled. Spatial extend, temporal extent, species of interest, the research project it was collected under are parameters you should specify in your data request
  3. Review the annual reports generated by all of the studies you intend to include in your request to be sure that the data is appropriate for your intended use.
  4. Complete and submit the Data Request Form and the Data Use Commitment.
  5. We will forward your request to all applicable field offices and allow one week for comment on the request. There may be cause to limit the distribution of certain data in raw form in which case we will aggregate to a reasonable level of granularity. We strive to complete data requests within 2 weeks of submission.
