Ventura River Watershed Adjudication

Casitas Municipal Water District is actively defending and protecting the District’s water rights in the case of Santa Barbara Channelkeeper v. State Water Resources Control Board; City of San Buenaventura; City of San Buenaventura v. Duncan Abbott, et al., Cross-Complaint, Superior Court of the State of California, County of Los Angeles, Case No. 19STCP01176.

If you received a notice or summons and wish to defend your water rights as a property owner, you should consider hiring your own attorney for your specific property rights. Because of its statutory responsibilities and mission, Casitas Municipal Water District is defending rights related to water supplied through your utility connection, not water rights associated with the property you own.

We understand many of you have questions regarding the adjudication process initiated by the City of Ventura. Although we are legally unable to give you advice about what you should do, we want to provide you with as much information as possible.  Below are links to public information shared by Casitas related to the adjudication. Since this is an active legal case there are details which must remain confidential.
