Water clarity and eelgrass
Posted: Sat Mar 21, 2026 7:36 am
Have others noticed the bay seems a lot murkier with less eelgrass than previous years?
Lack of eelgrass can decrease water clarity since the roots hold in sediment that is otherwise stirred up by the tides. And there is a positive feedback mechanism in that poor water clarity reduces the maximum depth eelgrass can survive in.
Yesterday, the water temperature got to 68F at Coronado bridge. 68F is supposed to be the upper range for optimum temperature for eelgrass and it is only going to get warmer in the summer. Pretty warm for what was officially the 1st day of spring (vernal equinox).
Less eelgrass isn't good for fishing, at least for most species (maybe not mud marlin).

FYI, I had 19 spotted bay bass, 1 corvina, 3 short halibut and 2 lizard fish yesterday, launching from Bayside in my tube. Slower than most years. Got a lot of short strikes, maybe a good year for lizard fish.
