Update: Channel Island Harbor Water Quality
OXNARD, Calif.- The City of Oxnard Channel Islands Response Team is monitoring the dissolved oxygen concentrations (and other parameters) at multiple locations along the Channel Islands Harbor on a weekly basis. Additionally, on August 6, the City deployed an automated remote sensor in the upper canal between Westport and Seabridge (parallel to Adriatic Street), continually monitoring the water at the site of the sensor to provide 24/7 coverage.
The remote sensor has been continuously recording a variety of water quality parameters. The data has indicated that the dissolved oxygen concentrations in the water have been fluctuating daily, with a few low concentrations during the night. Since Aug. 15, the remote sensor has detected a minor but steady decrease in the daily average concentrations of dissolved oxygen. Weekly manual sampling for dissolved oxygen throughout the Harbor by City staff has confirmed these findings.
This information indicates a very low oxygen event may be imminent, perhaps similar to the event that occurred earlier in the summer. The ecosystem is also exhibiting substantial, although not unusually high, algal biomass in the water column and water temperatures have increased 14 degrees since the end of June. These circumstances apparently preceded the low oxygen event earlier in the year, so it has also drawn the attention of the groups monitoring the harbor.
The public can view the test results at https://arcg.is/08ifCO on a geographic information system (GIS) map. The map contains the location of all the sampling sites and the data collected at those sites. The map also has a legend under the “Test Parameter” button to indicate what a normal range should be for each of the parameters that are being tested. Staff is working quickly to upload as much information as possible. At this time, the dissolved oxygen content, salinity, water temperature, and pH is available.
The City of Oxnard is requesting your assistance to be proactive and prepared in case the Harbor experiences another event. We are asking for residents living around the Harbor to watch the water and report anything that seems unusual. We encourage residents to document the change with photos. Low oxygen levels can cause fish to die off in the water. We are looking for boaters who are willing to volunteer their time to remove dead fish from the waters, should this happen due to low oxygen levels.
If you are willing and able to assist with either of the above, please contact (805) 385-8226 and email photos to CIHarbor@oxnard.org.
The City of Oxnard is a full-service general law city incorporated in 1903. Oxnard is the largest and most populous city in the County of Ventura, serving 200,000 culturally diverse residents.
