Here are just a few of the gorgeous illustrations from our new annual report! baykeeper.org/current-annual-r

Our special anniversary report covers all the essential areas of Baykeeper's work—from sampling, to planning, to stopping sewage , investigating harmful algae blooms, protecting river flows & so much more.

Deep thanks to Fiorella Ikeue for the beautiful artwork 🙏

We recently launched a new community science program to monitor in in collaboration with our partners at NOAA, USGS & the SF Estuary Institute!

We're training community volunteers to detect the spread of harmful in the Bay earlier and more precisely. It's part of Baykeeper’s long-term strategy to reduce in the Bay.

As we head into the summer--when conditions for red tides & other are ripe--help us put pressure on the Water Board to prevent toxic algae in the Bay!

The Board will be making an important decision on this issue in early July. We need your voice! baykeeper.org/act-now-dont-let

The Bay has experienced harmful algae blooms 2 years in a row ☹️

📢 We need your help to prevent future outbreaks!

San Francisco BaykeeperAct Now: Don't Let Algae Blooms Become Our "New Normal"For the past two summers, algae blooms and fish kills have cast light on a threat to the Bay that’s usually invisible: nutrient pollution. While nutrients sound like a good thing, excessive phosphorus and nitrogen – combined with warm sunny weather and stagnant water – provide ideal conditions for many types of algae to bloom, like the “red tide” that recently spread throughout the Bay. In the summers of 2022 and 2023, Baykeeper received numerous pollution hotline reports of murky, reddish-brown waters in different parts of the Bay.

Last summer's fish-killing bloom is back in the Bay:
“Two years in a row is quite alarming,” our science director Jon Rosenfield told KQED, noting that it remained unclear how bad the bloom will get.
“There’s really nothing that people can do to stop a bloom like this once it’s started. It just has to burn itself out.”

KQEDLast Summer's Fish-Killing Algae Bloom Is Back in the Bay | KQEDLocal agencies are closely monitoring a brown stretch of water that first appeared along parts of the East Bay shoreline last week and is confirmed to be the same type of algae bloom that killed thousands of fish in and around the bay last year.

Fresh water is “rushing like a firehose out of the delta” into the Bay says Baykeeper scientist @jarosenfield, and that’s helping to repress fish-killing --for now.

But we will need MAJOR wastewater upgrades to prevent red tides like the one we experienced last summer! sfchronicle.com/climate/articl
