The California Flood Management Districts geodatabase contains several spatial data layers indicating boundaries of various
local flood management agencies throughout the state. There are also attribute tables indicating current contact information,
updated as of Spring, 2006, as included in the Directory of Flood Officials, produced by the California Department of Water
Resources Division of Flood Management. Of the various layers, the most numerous are referred to as reclamation districts.
The reclamation districts layer is an indication of the approximate jurisdictional boundary of both currently active or once-active-but-now-inactive
reclamation districts. Districts have in some cases merged, dissolved, divided, and been modified since their original formation.
The reclamation districts indicated here were generated from a variety of sources, including (in order of boundary accuracy
preference) complete legal descriptions submitted at the time of District formation, CAD boundary files provided by District
engineers, boundaries digitized by Department of Water Resources Delta-Suisun Office over orthophotography, incomplete legal
descriptions submitted at the time of District formation, DWR Land Use maps, a 1997 California Office of Emergency Services
effort to map boundaries, and sundry other means. The work has essentially been an ongoing effort since the production of
the original 1997 layer, in order to improve that first effort somewhat. Most of the improvements have focused on Districts
within the Sacramento-San Joaquin Delta region, since DWR's office responsible for that area has undertaken most of the improvement
work. As a result, there are probably many remaining data gaps and inaccuracies, particularly in areas outside of the Delta.
This is particularly true of DWR maintenance areas and for levee districts, both of which will certainly require updating
in the future.
Flood management districts are local agencies/entities with primary flood control responsibility for a given area. There are
different types of flood management districts that exist within the State of California, but all of them, in varying capacities,
have responsibilities for flood maintenance and protection. For more information and detail about the data included in this
geodatabase, please contact the Department of Water Resources, Division of Flood Management, Delta-Suisun Marsh Office.
