Community Celebrates Lake Merritt Improvements

Friday February 22nd was a day of celebration at Lake Merritt.  A much-anticipated effort to restore Lake Merritt and reconnect it with the Bay reached a major milestone when the channel under 12th Street was reopened.  (Read our previous blog about the history of Lake Merritt and this improvement project).  But for me, Friday was more than a celebration of the long-needed improvement of one of my favorite parts of the Bay; it was a poignant reminder of what people are capable of accomplishing when they join together and organize their community – just like Save The Bay is doing with our new initiative, For The Bay!

For The Bay is a way for residents from across the Bay Area to get involved and work together on behalf of the Bay.  San Francisco Bay provides habitat for hundreds of species of wildlife, helps keep our communities safe from severe storms and flooding, and supports our local economy by creating hundreds of thousands of jobs.  Because the Bay is our greatest natural and economic resource, we all need to help protect and restore the Bay for ourselves and the next generation.  By building a network of Bay Area residents who are For The Bay, we can reach a large number of people with breaking news, calls to action, volunteer activities, and opportunities to get involved.  As Friday’s celebration at Lake Merritt demonstrated, getting involved matters!

Here’s how Oakland residents made a difference: Though we call it a lake, Lake Merritt is actually a tidal lagoon connected to San Francisco Bay by a half-mile long channel that has been dammed since 1869.  In 2001 a group of Oakland residents responded to a private shoreline development proposal by submitting their own plan to restore the lake and create a public park space. Not only did this plan go through, but more than 80% of Oakland residents voted for a bond measure (Measure DD) to fund these improvements.  The result?  New local jobs, a cleaner Lake Merritt, and new pedestrian and bike trails that will eventually link with the Bay Trail.  What an inspirational example of the power people have to make an impact in their community!

Now I know you’re inspired by what Oakland accomplished, so take a minute to think about the Bay and what it means to you.  You and millions of other Bay Area residents walk, run, work, and play in and around San Francisco Bay every day.  To ensure a healthy future for San Francisco Bay and protect our quality of life, we need to act now to restore and protect the Bay.    Show your Bay Area pride and join thousands of residents who are For The Bay!

After 143 years, Oakland’s Lake Merritt Reunites with the Bay

A gem at the heart of Oakland, Lake Merritt has been many things – the nation’s first wildlife refuge, beloved waterway, sewage-filled cesspool, and even the rumored home to a lake monster. There’s one thing that Lake Merritt has never been, however – and that’s a lake.

What we now call Lake Merritt has for most of the past ten thousand years been a tidal lagoon where the waters of several East Bay creeks met the brackish tides of the Bay. Ringed with mudflats and tidal marsh, this lagoon was home to an abundance of native wildlife, including hundreds of species of birds.

This changed dramatically in1869 as Oakland Mayor Samuel Merritt dammed the channel connecting the lagoon to the Bay. Later becoming the 12th Street Bridge, the lagoon’s water was forced through narrow culverts on its way in and out of the Bay, significantly reducing circulation and largely disconnecting the waterway from the rest of our great estuary.

Over the next century, the lake was inundated by raw sewage and considerable amounts of pollutants. 62 storm drains were routed straight into the lake, bringing with them car oil and other toxins from the city’s streets. To this day, the majority of these storm drains remain unfiltered. All of this has resulted in poor water quality, low oxygen levels, algae blooms, and numerous massive fish kills. The Environmental Protection Agency declared the lake an “impaired water body” in 1999.

Residents’ Effort Leads to Historic Project to Improve the Lake

Spurred by a development proposal near the Lake’s 12th Street shoreline, a group of residents got together to chart out a different future for the Lake. Named the Coalition of Advocates for Lake Merritt, the group drew up a proposal to reduce the bridge from twelve lanes to six, increase the width of the channel, and increase public access and wildlife habitat.

Oakland elected officials supported the plan and with the overwhelming approval of a bond measure (Measure DD) in 2002, the plan was put into action. Since that time, the City of Oakland has rebuilt the 12th Street Bridge and is actively removing tide-blocking culverts and widening the channel that connects the lake to the Bay. Several acres of newly restored wetlands are being created along with a 4-acre park and numerous walking paths.

Once the project is completed, estimated by the City to be late this year, the amount of water currently going in and out of the lake with the tides will be doubled, significantly improving water quality and circulation. The new wetlands will filter toxins out of the water, provide habitat for young fish and birds, and offer a pleasant experience for the thousands of walkers, joggers and bikers that enjoy the lake every day.

While there is still considerable work left to be done to restore the health of Lake Merritt, this project can bring a renewed sense of hope and determination that this is just the beginning of an ecological transformation in the blue heart of the city.

UPDATE – February 2013:

The 12th Street Bridge (really, more of a dam), which had blocked regular Bay tides from Lake Merritt for over 140 years has now been completely removed! The City of Oakland held an event to celebrate – read more about the celebration our Save The Bay blog here. The new bridge will allow for a 100-foot wide free flowing tidal channel underneath, doubling the amount of water flowing between the Lake and the Bay. A new tidal marsh area has been carved out to improve wildlife habitat and work to build new tails and landscaping is currently underway. This bridge replacement was the biggest piece of the project. Next the City of Oakland will be working to remove/alter other impediments (such as the 10th Street Bridge) which have been preventing boats for over a century from being able to go between Lake Merritt and the rest of the Bay. Check the City’s website, or back on this blog for future updates. Additional information about the City’s work to stop pollution and restore habitat can be found on their Creeks, Watershed & Stormwater website.

UPDATE – June 2013:

What’s next for improvements to Lake Merritt? City staff are currently designing human-made floating wetlands, to be installed near the shoreline to help filter out toxins of the water and provide habitat for wildlife.
