Field Updates February 2020: Creek and Eelgrass

Creek Water Quality February was a month marked with warm temperatures and low precipitation here in the Morro Bay watershed. In February 2019, the San Luis Obispo CIMIS rain gauge received 7.48 inches of rain, with 57% of days during the month recording rainfall. Comparatively, this year’s rainfall has been much lower, with a February monthly total of 0.01 inches of rain and only one day with rainfall as of February 28. Low precipitation levels have led to low flows in our creeks, as can be seen in this picture of Dairy Creek, a tributary of Chorro Creek. The amount …

This month, our field staff have been busy monitoring eelgrass success in the bay and water quality in the creeks that drain to the Morro Bay estuary. Eelgrass monitoring and restoration success If you spent time out on the bay in January, you might have noticed the really high tides. January 2020 had King Tides, meaning that the high tides were much higher than normal. These extreme high tides are mirrored by extreme low tides. We always take advantage of these extreme low tides to monitor eelgrass, as we have a wider window than normal to conduct our monitoring. Eelgrass …

Eelgrass fieldwork depends on tides Fall is a busy eelgrass season for field staff at the Estuary Program. The exact timing of our field work depends on when the good low-tides occur, which varies slightly from year to year. This year, October had a few days that had tides low enough to expose the eelgrass during daylight hours. This doesn’t always happen—sometimes the low tides we need happen after sundown and before sunrise. We were glad to see good tides in combination with good timing because we have a few different projects going on. Monitoring permanent eelgrass plots First …

Pikeminnow Management Chorro Creek used to be home to a healthy population of steelhead trout (Oncorhynchus mykiss), however their numbers have declined. While there are multiple factors that contribute to this, a fish called the Sacramento pikeminnow (Ptychocheilus grandis) put pressure on steelhead. Pikeminnow eat juvenile steelhead and compete with steelhead for food and habitat. While native to other parts of California, pikeminnow are not native to the Morro …
