The bill establishes a new mechanism for voluntary donations to support the newly created "sea lion predation control account" during the vessel registration process, allowing vessel owners to contribute $1 or more when registering or renewing their vessel registration. These donations will be directed to the account, which is established in the state treasury specifically for managing pinniped populations to protect salmon levels in the lower Columbia River area. The bill also clarifies that funds from this account cannot replace existing funding for pinniped management provided to the Department of Fish and Wildlife or other state agencies.

Additionally, the bill amends existing regulations surrounding the treasury income account, ensuring that all earnings from investments of surplus balances are deposited into this account. It specifies that no appropriation is required for payments related to federal programs as mandated by the federal Cash Management Improvement Act of 1990, and outlines the process for distributing earnings to various accounts based on their average daily balances. The act is set to take effect on July 1, 2026, with staggered effective dates for various sections.
