The Story of Lake Mathews
Lake Mathews, the heart of the reserve, plays a vital role as a water source for Southern California. Designated a 4,000-acre ecological reserve in 1982, the reserve expanded significantly in the early 1990s following the discovery of the Stephens’ kangaroo rat, adding 9,000 acres to its protected status.
Planning Your Visit
Located in Cajalco Canyon at the base of the Temescal Mountains, the RCHCA manages approximately 11,243 acres within the larger 13,000-acre reserve. Check for any necessary permits or access restrictions before your visit.
Is Lake Mathews Open to the Public?
While the surrounding Estelle Mountain Reserve offers scenic overlooks and hiking trails, Lake Mathews itself is currently closed to the public due to its crucial role as a reservoir, managed by the Metropolitan Water District (MWD) and the RCHCA, and for security reasons.
The closure protects the water quality, preserves the delicate ecosystem, and ensures the safety and continued operation of this vital resource. While direct access to the lake is prohibited, visitors can still enjoy stunning views from the Estelle Mountain Trail and other designated areas within the reserve.
The future of public access to Lake Mathews remains a topic of discussion. Balancing public recreation with protecting the water supply and ecosystem presents a complex challenge. Some believe limited, managed access might be possible in the future, while others prioritize maintaining current restrictions. Research is ongoing, and how things evolve remains to be seen.
What is Lake Mathews Used For?
Lake Mathews plays a vital role in Southern California, serving both as a major reservoir and a thriving ecological reserve.
As the terminus of the Colorado River Aqueduct, Lake Mathews stores water before distribution by the MWD, acting as a buffer against drought. Nestled within the 13,000-acre Lake Mathews Estelle Mountain Reserve, it sustains a biodiversity hotspot, home to over 250 plant species and a rich variety of animal life.
The MWD and RCHCA jointly manage this dual-purpose resource, balancing water supply needs with habitat conservation. Ongoing research continues to unveil the intricacies of this ecosystem.
While the lake itself is closed to the public, the surrounding Estelle Mountain Reserve offers hiking trails with breathtaking views. Always check with managing agencies for any access restrictions before your visit.
Why is Lake Mathews Closed to the Public Today?
Lake Mathews’ closure stems from a combination of factors aimed at preserving this vital resource.
As a major reservoir serving Southern California, public access would risk contamination. The closure also protects the delicate ecosystem of the Estelle Mountain Reserve, a haven for diverse wildlife. Additionally, security concerns for this crucial infrastructure element necessitate restricted access.
While direct lake access is prohibited, hiking trails like the Estelle Mountain Trail offer stunning panoramic views. Ongoing research and monitoring ensure the long-term health of the lake and its environment. The closure reflects a balance between human needs and environmental protection.
