My firm has compiled this helpful Water Rights Annual Filings Checklist 2012 to help California water rights holders remember the deadlines for various regulatory filings. The checklist covers all types of water rights, appropriative and riparian, to surface water and groundwater, as well as cessation of use and Department of Fish and Game filings. Due to some irregularities in how the California State Water Resources Control Board collects filings, e.g., setting different deadlines than are in the statute, make sure you read the descriptions below as well as the entries in the table. If you have any questions, please ask.
