Creek with rocks_Morro Bay National Estuary Program

    Things are heating up this summer! According to a local weather station monitored by California Irrigation Management Information System (CIMIS), the average air temperature increased from about 54°F in April and 57°F in May, to over 62°F during June. In our local creeks, we also have noticed a similar climb in stream temperatures. A water temperature logger on San Luisito Creek recorded a maximum seven-day rolling average of 57.7°F (14.3°C) during May, and a maximum seven-day rolling average of 59.3°F (15.2°C) during the first half of June. For more information on how we track temperature in our local …

Field Updates May 2021: Spring Eelgrass Monitoring

  A quick introduction… Hi everyone! My name is Bret, and I am the new Monitoring Projects Manager for the Estuary Program. I’m a recent transplant from the Midwest, but the West Coast has been calling to me for quite some time. As I get settled here in Morro Bay, I look forward to learning more about our estuary as well as how to be a steward of our watershed. I arrived in Morro Bay at the beginning of April, just in time for bioassessment (you can read more about bioassessment in our April Field Updates blog post). I really …

Field Updates March 2021: Volunteer Monitoring Program Updates and Bioassessment Site Scouting

Monitoring staff conducts bioassessment site scouting in the Morro Bay watershed

  Read each month’s Field Updates post to see what our Monitoring Team have been up to.  Updates on the Volunteer Monitoring Program As of March 2nd 2021, San Luis Obispo County moved from the purple or “Widespread” tier back into the red tier. The Morro Bay National Estuary Program’s current COVID-19 Safety Policy allows for volunteer monitoring when the San Luis Obispo County risk level is at or below the red tier designation, as outlined by COVID19.ca.gov. As such, the Estuary Program has slowly begun inviting back volunteers in a limited capacity. We have coupled this change with additional …

A Day in the Life of a Field Tech: Eelgrass Monitoring, by Blake Toney

A staff member stands in waders in a puddle on the mudflat.

In today’s post, Blake Toney, former Morro Bay National Estuary Program Field Tech, reflects on an early morning spent monitoring eelgrass during a very low tide in Morro Bay.  5:40 a.m. I arrive at today’s site a few minutes before my coworkers to get my bearings. The sun will not rise for another hour, but already the dark sky has begun to take on a hint of blue so faint it becomes harder to see when I concentrate on it. The moon provides some light, enough for me to trek out across the mud after struggling to fit into my …

Director’s Desk: We Are Still Here, Monitoring, Restoring, Educating

Monitoring Coordinator, Makenzie, sports a mask during fieldwork.

    We are in a time of colliding arcs of history, immersed in the uncertainty and heightened emotions of change. The backdrop of this moment, like all moments, is our Earth. The place that holds and nurtures us. In the Morro Bay watershed, we are exceedingly lucky to be able to enjoy the beauty and peace of our estuary. The fluidity of the bay—the changing of the tides, the movement of the birds, the ever shifting fog line—brings both comfort and a mirror to the constant change around us. Although each of us may not be able to get …

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 …

Updates from the Field, December 2019: wildlife, staff changes, and restoration

Morro Bay estuary with bat ray pits, Morro Bay National Estuary Program

    Wildlife observations The fall is a great time for observing invertebrates along the mudflat in Morro Bay, and lucky for us, we are out monitoring eelgrass every fall. This often leaves us wondering, “What is this?!”, but sometimes we find the answers while monitoring eelgrass health. For example, we have been seeing a number of egg masses such as this one, tucked away on blades of eelgrass. Considering the diverse array of organisms that utilize eelgrass as habitat, we were left wondering which creature had been laying the eggs. Sometimes though, you wander along the right part of …
