Draft California 2026 Integrated Report (303(d) List/305(b) Report)

Supporting Information

Regional Board 5 - Central Valley Region

Water Body Name:	Russell Ave Drain (Fresno County)
Water Body ID:	CAR5412000020101115120553
Water Body Type:	River & Stream


DECISION ID	169198	Region 5
Russell Ave Drain (Fresno County)

Pollutant:	Specific Conductivity
Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision:	Do Not List on 303(d) list (TMDL required list)(2018)
Revision Status	Revised
Impairment from Pollutant or Pollution:	Pollutant

Regional Board Conclusion:	Readily available data for this waterbody were not used to determine standards attainment as the status of the waterbody as a water of the United States is uncertain. The 303(d) list is authorized under the Clean Water Act and is therefore limited to waters of the United States. Data will be used to determine standards attainment during a future Integrated Report cycle if it is determined that this water body is classified as a water of the United States.

Regional Board Decision Recommendation:	After review of the available data and information, RWQCB staff concludes that the listing status for this water body-pollutant combination should not change this cycle because of a lack of clarity in the status of this water body under the Clean Water Act.

State Board Review of Regional Board Conclusion and Recommendation:

State Board Decision Recommendation:	After review of the available data and information, SWRCB staff concludes that the water body-pollutant combination should not be placed on the section 303(d) list because it cannot be determined if applicable water quality standards are not being exceeded.
