The 2019 Superbloom is a natural phenomenon unlike anything the City has ever experienced and demonstrates the extreme beauty of the City of Lake Elsinore. We would like to thank residents and visitors for their patience as we faced substantial challenges related to this international attraction. At this time, the City is experiencing a high call volume. Walker Canyon is currently open, however parking is very limited. Lake Street and Nichols Road are also now open. For more information, call the Superbloom Hotline at 951-471-1238 or check the City's social media feeds.

The organization of a “volunteer effort” to aid the Sheriff of a county in America became formally known as a posse back to the early 1600’s. The name “posse” is derived from the familiar Latin term “posse comitatus” which translates to a “volunteer effort of the county.”

Though much has changed over the 300+ years since the formation of the first American posses, the origin of volunteerism to benefit the citizens of the county still remains the cornerstone of even today’s dedicated posses.
