Draft 2026 Integrated Report

The 2026 Integrated Report (IR) assesses the quality of the surface waters in the state and identifies waterbodies that are not meeting water quality standards. These standards support the designated beneficial uses that protect water quality for drinking water, recreation, aquatic life, and agriculture. Waterbodies that do not meet one or more of their beneficial uses are classified as impaired in the IR and placed on the Clean Water Act 303(d) list.

Draft 2026 IR Assessment Methods

The 30-day public comment period for the Draft 2026 Integrated Report Assessment Methods began on January 22, 2025 and ended on February 20, 2025. If you have comments on the assessment methods, these should be raised now during this public comment period. Otherwise, they will be considered out of scope for 2026 and addressed during the 2028 IR cycle.

Call for Data: 2026 Integrated Report

DWQ assembles and evaluates all readily available and credible data to determine whether a waterbody is supporting or not supporting its beneficial uses as mandated in 40 CFR 130.7(b)(5). Data are compared to Utah’s Standards of Quality for Waters of the State using the 303(d) Assessment Methods. Interested parties are encouraged to submit credible data as described in the 303(d) Assessment Methods. Note: If you or your organization already submit data to DWQ through our Cooperative Monitoring Program, you don’t need to submit data through the Call for Data process.

Data submitted to DWQ or obtained by DWQ during the Integrated Report (IR) data compilation process are integrated into DWQ’s assessments as described in Table 3 of the 303(d) Assessment Methods and are subject to DWQ’s data management and quality assurance/quality control (QA/QC) processes. Should any data and information not be included in the IR assessment process, DWQ will clearly document which dataset (or datasets) were not included and the reason for rejecting them from the assessments.

ATTENTION: If you submit data through DWQ’s Cooperator Program, you should not submit data during the Call for Data. If you have questions about DWQ’s Cooperator Program, please contact Ellen Bailey (ellenbailey@utah.gov). Additionally, if you have already submitted your high frequency/continuous data to DWQ’s Continuous Water Quality Database, you do not need to resubmit your data. Data and information that are not brought forward during the IR’s Call for Data or presented to DWQ in accordance with the processes and timeframe discussed on this webpage or in the 303(d) Assessment Methods will not be treated as readily available for the purpose of assessment decisions during the 2026 assessment cycle.

Waterbody Types

The IR reports on the following for 303(d) assessment purposes:

Flowing surface waters of the state
Canals as identified in site-specific standards or named in the list of waters with the designated use classifications
Lakes, reservoirs, and ponds

All other waters are currently reported through other programs within DWQ.

Data Requested

DWQ is requesting the following data for the 2026 IR:

Quantitative and qualitative data as described in Table 10 of the 303(d) Assessment Methods
Data and information from October 1, 2018—September 30, 2024
Data not already available in DWQ’s Ambient Water Quality Data Management System (AWQMS), EPA’s Water Quality Portal, U.S. Geological Survey’s (USGS) NWIS, DWQ’s Continuous Water Quality Database, and Utah State University’s BugLab. DWQ is already compiling the data and information from these sources.
