Results - Summary of 2019 and 2020 Data
The diagram above shows the effect of surface and bottom waters of tributary and bay stations on each species group. The pie charts show their suitability in each of these regions indicated by color.
Species were affected differently by the parameters measured. Below states which factors were problematic for each group.
Finfish were affected by: low DO
Shellfish were affected by: low DO
Crabs were affected by: low DO
SAV were affected by: high Chl-a
Average fecal coliform levels were significantly higher (p = 0.00005) at tributary stations (456.85 MPN/100 mL) than at bay stations (47.79 MPN/100 mL).
Data is all preliminary and based on 2019 season measurements. Sampling in future seasons can enforce data and average out seasonal variation to better understand the overall waterbody.
