Data Solicitation

data solicitation period

The State Water Board and Regional Water Boards will soon begin developing the 2020 California Integrated Report. The 2020 Integrated Report will include information primarily from the Central Coast, Central Valley and San Diego Regional Water Boards.

Data and information submitted to the State Water Board during the current solicitation period will be used in developing the individual 2020 Regional Integrated Reports. Regional Boards will send public notices when the 2020 Regional Integrated Reports are completed and available for public comment. Once adopted, the three individual Regional Integrated Reports will be combined at the State Water Board to create the 2020 California Integrated Report.

These data requirements are also found in the Enclosures of the 2020 Solicitation Notice.


To be included in the 2020 California Integrated Report, all data submittals must be received by State Water Board staff before 5:00 p.m., June 14th, 2019.



Data Submittal Basics


What is the overall data submittal process?

The figure below illustrates the process for submitting data for the Integrated Report. Data that can be accepted by the California Environmental Data Exchange Network (CEDEN) must be submitted to CEDEN. Data that is not CEDEN compatible can be submitted via the Integrated Report Upload Portal. In addition, all data submittals (both CEDEN compatible and non-CEDEN compatible) must be accompanied by a Quality Assurance Project Plan (QAPP), which is also submitted via the Integrated Report Upload Portal.

CEDEN Compatible

If you are submitting a CEDEN-compatible data type, your data should be submitted through CEDEN. This includes water chemistry, sediment chemistry, toxicity, tissue and bioassessment data. This data will also require geospatial information, comprised of latitude, longitude and datum. This can be submitted through CEDEN.

Details for submitting data to CEDEN are found here, or in Enclosure 2 of the Solicitation Notice.

Your data are also required to have a QAPP. QAPPs cannot be submitted through CEDEN. This must be sent through the Integrated Report Upload Portal.

Details on QAPP requirements and submittal instructions are found here, or in Enclosure 4.

Non-CEDEN Compatible

If you are submitting a data type that is not CEDEN compatible, you must follow the instructions for submitting non-CEDEN compatible data. This includes continuous monitoring data, and narrative or photographic evidence. Detailed instructions are found in Enclosure 3 and here.

These submissions will also require geospatial information and a QAPP, submitted via the Integrated Report Upload Portal.

For QAPP requirements and submittal instructions, see Enclosure 4.





When should data be submitted?

Data can be uploaded to CEDEN at any time. However, data must be submitted by June 14, 2019 to be evaluated for the 2020 California Integrated Report. Data submitted after June 14, 2019 will be considered in future integrated reports.

Who can submit data?

Any person or entity (including but not limited to private citizens, public agencies, local, State, and federal governmental agencies, non-profit organizations, and businesses) possessing information regarding the quality of the State’s waters may submit data and information. Though the 2020 California Integrated Report will include listing assessments by the Central Coast, Central Valley and San Diego Regional Water Quality Control Boards, we encourage a continual submittal of data regardless of region.

How do we define information and data?

“Data” are numeric measurements of water quality or environmental conditions (i.e., measurements of physical, chemical, or biological characteristics in aquatic environments).

“Information” includes any documentation, such as narrative of photographic evidence, that pertains to the attainment of existing water quality standards. Standards include beneficial uses of water and water quality objectives/criteria as listed in the Regional Water Quality Control Plans (Basin Plans), statewide water quality control plans (e.g., the California Ocean Plan), the California Code of Regulations, and pertinent federal laws and regulations.

Data and information submitted may pertain to individual waterbody segments, entire waterbodies, or whole watersheds in California.

How do we define “readily available data and information”?

“Readily available data and information” is defined in Section 6.1.1 of the Water Quality Control Policy for Developing California’s Clean Water Act Section 303(d) List (Listing Policy). This includes data that are submitted to CEDEN. If CEDEN is unable to accept a subset of data and information, we will accept that data and information if submitted via the Integrated Report Upload Portal, as described in Enclosure 3.

What kind of data should be submitted?

All new “readily available data and information” will be considered. Any data and information that contribute to a more complete understanding of the quality of the state’s surface waters should be submitted. This includes data that show water quality standards are being exceeded or not being exceeded. Any data not captured in the previous data solicitation periods should be submitted. This includes data collected since the end of the last solicitation period (May 2017) as well as data collected prior to that date but not submitted.

The California Integrated Report uses both quantitative and qualitative information. The bulk of the data used in the California Integrated Report is quantitative, or numeric-based. These data provide the basis for primary lines of evidence (LOEs). Qualitative information consists of non-numeric evidence such as photographs or narrative data. These are used as ancillary evidence in the development of LOEs. For greater detail on how different data types are used to develop the Section 303(d) list, see Section 3 of the Listing Policy.

What kind of data should not be submitted?

Please do not submit:

  • Data that was previously submitted as part of a past Integrated Report listing cycle
  • Data that has already been submitted into CEDEN
  • Data pertaining to groundwater

What if I have already submitted data to federal systems like U.S. EPA’s Water Quality Exchange?

We recognize that federal, tribal, and other entities submit data directly to the U.S. EPA following the water quality exchange framework and it is not feasible to require that those datasets also be uploaded into CEDEN. Consequently, Water Board staff will pull data directly from the National Water Qualify Portal which connects to Water Quality Exchange as well as other federal databases and attempt to translate that data into a CEDEN compatible format for use in the Integrated Report process. Datasets will only be used for the California Integrated Report if they conform to the minimum data elements and quality requirements outlined in Enclosures 2 and 4.
