Attached to this news article are "Frequently Asked Questions" complied by agencies representing the Eastern Sierra Unified Command as they coordinate and manage 2023 Spring snowmelt runoff emergency conditions.

On March 8, the Inyo County Board of Supervisors proclaimed a local state of emergency as a result of the early 2023 atmospheric river events and projected spring runoff conditions.

The declaration stated, in part: “… 2023 storms and runoff conditions threaten the safety of property and persons in Inyo County by flooding private, Tribal, and public property; damaging or destroying infrastructure including roads, bridges, water conveyance and diversion structures, dust control apparatus, sanitary facilities, and campgrounds; creating conditions that propagate mosquitoes and other vectors that harbor disease and threaten public health; and, posing long-term environmental threats associated with the spread of invasive species …”

The County of Mono and the Town of Mammoth Lakes made similar declarations on March 8 due to the massive amount of snow burying homes and businesses. A Unified Command was immediately formed to organize and accelerate snow removal and runoff preparation efforts.
