Modifying the requirements and allocations for multi-year flex accounts.

SB 58 modifies Kansas' rules for "multi-year flex accounts" related to groundwater water rights. It allows the chief engineer to create these accounts (valid for up to five years) that temporarily suspend a base water right, enabling flexible water use for farming while ensuring it doesn't harm existing rights or increase total water diverted. The bill defines key terms like "base average usage" (calculated from historical 2000-2009 irrigation data) and sets strict conditions for eligibility, such as no prior water bank deposits or pending regulatory actions. This directly affects groundwater right holders who wish to adjust their water use patterns without altering their underlying water rights.
