The Lake at Lakeshore Park

Lakeshore Park was established in the 1960's as part of a large housing development.  The park is approximately 26 acres in size with the lake waterbody itself being 16 acres.  The park is used regularly as a recreation area by residents for walking, jogging, fishing, birdwatching and other activities.

Update 11/17/2022

The contractor completed their work at the end of October.  Over the past few weeks, some algae material has begun to collect on The Lake.  In the coming weeks, City staff will follow up with additional surface cleanup. 

Update 10/25/22:

The contractor performed some final surface cleaning yesterday and will be on site today to complete the final surface cleaning.   A substantial amount of algae material was harvested out of the lake.  As of Friday, the dissolved oxygen levels remained good.   We expect that to remain the case today and staff will be getting additional readings. 

City staff will continue with the additional aeration as we move into early November with temperatures dropping and sunlight hours decreasing.  With the bulk of the algae material having been removed, we do not expect to see a significant algae die-off or adverse impact on oxygen levels with the seasonal change.  Dissolved oxygen levels will continue to be monitored closely for at least the next couple of weeks.

Update 10/19/2022:

The Lake at Lakeshore Park, like many other Bay Area water bodies, experiences algae blooms in the summer and into the fall.  We believe the current growth has been exacerbated this year due to longer-period heat waves.  The general lack of rainfall to more fully replenish the waterbody over the course of the last rainy season, which in turn produces higher concentrations of nutrients such as nitrogen and phosphorus, can also be a factor in the increased growth

The City’s contractor will be on sight this week to remove the heaviest algae material on the east side along Scarborough Dr. and then smaller pockets, as needed.  Removing all of it would be a challenge as we want to minimize disturbing of the lake bottom.  The removal, in addition to improving the aesthetics, will limit the level of die-off as part of the algae’s natural cycle. This process should take 2-3 business days.  

City staff will continue to monitor the oxygen levels and install air compressors as a temporary means of elevating oxygen levels, should that be required.
