Supporting Information

Regional Board 6 - Lahontan Region

Water Body Name: Honey Lake Wildfowl Management Ponds
Water Body ID: CAL6372009519980806091131
Water Body Type: Saline Lake
 
DECISION ID
5540
 
Pollutant: Flow alterations
Final Listing Decision: Delist from 303(d) list (TMDL required list)
Last Listing Cycle's Final Listing Decision: Delist from 303(d) list (TMDL required list)(2006)
Revision Status Original
Reason for Delisting: Impairment due to non-pollutant (4C)
Impairment from Pollutant or Pollution: Pollution
 
Weight of Evidence: Based on the readily available data and information, the weight of evidence indicates that there is sufficient justification in favor of removing this water segment-pollutant combination from the section 303(d) list in the Water Quality Limited Segments category. This conclusion is based on the staff findings that the original listing basis is faulty due to lack of data and the fact that the listing was not for a pollutant.
 
RWQCB Board Decision / Staff Recommendation: This is a decision made by the State Water Resources Control Board and approved by the USEPA in 2006 . No new data were assessed by the Regional Board for 2008. The decision has not changed.

Data Used to Assess Water Quality: The original basis for the listing of this water body was best professional judgment based on concerns over low water levels during 1980s drought.

Therefore, the listing basis was faulty due to lack of data. Additionally, the listing is not for a pollutant. However, this water body is also listed for pollutants that may be related to the flow alteration (metals, salinity/TDS/chlorides, trace elements), and will remain on the list for those pollutants.
