Drainage District #100 Data Sheet

Drainage District No. 100 (DD100) was originally established on August 30, 1915, under the California Water Act of 1913. The District was established to provide irrigation and stormwater drainage services to the fledgling rice industry surrounding the small agricultural communities of Richvale and Nelson. The District provides drainage of irrigation and stormwater flows to approximately 486 agricultural and rural residential parcels. The District is located in the Butte Creek Watershed.

The majority of Drainage District No. 100 has been indentified as a 100-year flood zone by the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps. Additionally, mapping performed by the State of California Office of Emergency Services (OES) includes almost the entirety of the District in several dam failure inundation zones including Oroville Dam, Thermalito Afterbay and Thermalito Forebay.
