Water Quality Objective/Criterion: |
Waters shall not contain concentrations of chemical constituents in amounts which adversely affect the agricultural beneficial use. In addition, waters used for irrigation and livestock watering shall not exceed concentrations for those chemicals listed in Table 3.4 (Water Quality Control Plan, Central Coast Basin, Chapter III, Section II.A.2 Objectives for all Inland and Surface Waters, Enclosed Bays and Estuaries). Table 3-4 (page III-9) lists the maximum concentration for boron for irrigation supply is 0.75 mg/L. |

Spatial Representation: |
Data for this line of evidence for Orcutt Creek was collected at 3 monitoring sites [ 312ORB-Orcutt Solomon Creek at Black Road, 312ORC-Orcutt Solomon Creek u/s Santa Maria River, 312ORI-Orcutt Solomon Creek at Highway 1] |
Temporal Representation: |
Data was collected over the time period 1/12/2000-4/6/2001. Santa Maria watershed is one of five annual rotation areas that are monitored for conventional pollutants by CCAMP staff monthly for one year. Toxicity monitoring is conducted twice during the rotation year (winter and summer) at a subset of sites. |

Waters shall not contain concentrations of chemical constituents in amounts which adversely affect the agricultural beneficial use. Interpretation of adverse effect shall be as derived from the University of California Agricultural Extension Service guidelines listed in the Central Coast Basin Plan and identified as the level at which severe problems may occur when EC exceeds 3.0 mmho/cm in irrigation supply water (meaurements reported at 25 degrees C). EC measured, at 25 degrees C , is referred to as specific conductivity. Also note that 1 mmho/cm = 1000 uS/cm. |

Water Board staff assessed SWAMP RWB3 CCAMP Santa Maria Rotation data for Orcutt Creek to determine beneficial use support and results are as follows: 4 of 12 samples exceeded the water quality threshold for Turbidity. |
Data Reference: |
Field, Habitat, Sediment, Toxicity, Water data for the 2020/2022 integrated report in Region 3. |

Water Quality Objective/Criterion: |
Waters shall be free of changes in turbidity that cause nuisance or adversely affect beneficial uses (Water Quality Control Plan, Central Coast Basin). |
Objective/Criterion Reference: |
Water Quality Control Plan for the Central Coastal Basin |
|
Evaluation Guideline: |
Turbidities of 40 NTU or greater can cause a reduced foraging efficiency and a shift in prey selection in piscivorous fish (largemouth bass) due to interference with their ability to find prey (Shoup, D.E. and Wahl D.H., 2009). |

Data Used to Assess Water Quality: |
From new listing proposal: Regional Board staff is proposing that multiple water bodies (including Orcutt Solomon Creek) within the Santa Maria watershed be listed for unionized ammonia. The impairment is evidenced by levels of unionized ammonia greater than the general numeric water quality objective of 0.025 mg/l. The Regional Board assessed CCAMP data and results are as follows for two sites on Orcutt Solomon Creek: 3 of 11 and 5 of 12 data points exceed the criterion.
See CCAMP data for further information (CCAMP, 2004). This constituent was not included in the last (2002) data evaluation because data had not been processed in time to meet the 2002 deadline. |

Spatial Representation: |
Data for this line of evidence for Orcutt Creek was collected at 2 monitoring sites [ 312ORI-Orcutt Solomon Creek at Highway 1, 312ORC-Orcutt Solomon Creek u/s Santa Maria River] |
Temporal Representation: |
Data was collected over the time period 1/27/2005-12/14/2006. Cooperative Monitoring Program (CMP) staff conduct monitoring for conventional pollutants at all Ag Waiver monitoring sites monthly. CMP staff also conduct water toxicity monitoring quarterly and sediment toxicity monitoring annually (in spring). |
Environmental Conditions: |
Staff is not aware of any special conditions that might effect interpretation of the data. |
QAPP Information: |
All data was collected following the Standard Operating Procedures and Data Quality Objectives outlined in the Cooperative Monitoring Program QAPP, (Clark and Ogle 2006). QA data are included in submission. All data are flagged as appropriate. |
