Golden Gate Park’s Middle Lake – Breaks Ground

INTERSTICE is proud and excited to be part of the team that is undertaking the restoration of a critical piece of green infrastructure in Golden Gate Park; we are re-building Middle Lake.  This freshwater lake is one in a series of three lakes called the Chain of Lakes, which flow north from South Lake, to Middle Lake, and into North Lake at the western end of the park.  The original design & construction of these lakes dates back to 1898 and all required a clay liner to hold water over the ancient sand dunes that underlie the park.

Following a year plus long design process, construction of the project began in the early months of 2023 with the selective removal of certain trees and the protection of many other existing mature trees in preparation to rehabilitate the lake.  

INTERSTICE, as the landscape architect, is working with Civil Engineers AGS and Woodard & Curran, overseeing the new lake design installation to achieve improved accessibility and enjoyment for park visitors, and a diverse plant and aquatic ecology that will provide improved habitat for insects, birds, amphibians, reptiles and mammals that constitute the spectrum of the wildlife that inhabits and moves through Golden Gate Park. Bauman Construction is the General Contractor leading the construction effort working with the SF Recreation & Parks Department and SF Department of Public Works.

This significant undertaking includes replacing the clay liner lake bottom and increasing the water depth, clearing the pipes connecting Middle Lake to South and North Lakes, and rehabilitating the rock cascade that connects to the Fly Casting Pools.

The new design includes a perimeter loop trail that bridges the cascade, significant and diverse native and aquatic plantings surrounding the lake, furnished seating areas with  lookouts along the new pathway which encircles the lake and climbs the slope beside the cascade.  The future plantings include over a dozen native tree species, over50 species of native understory plants, including shrubs, groundcovers, grasses, rushes and aquatic and riparian species located at the lakes edge.

The establishment of the clay liner and lake edge are the first phase and significant part of the work.

We look forward to sharing more progress as the liner is completed and the lake starts to take shape this Spring.
