Link to the California bill. From the Meetings of the Mind blog:
"In seeking to meet the needs of residents, businesses and the environment, California lacks a comprehensive and accurate way to assess the water use and supply under its management responsibility. The State of California currently lacks the water data, or the widely adopted practices and technologies, which will enable better water management by its own governmental agencies. In addition, water infrastructure throughout the state is aging and in need of repair, numerous communities are without safe water, and many suffer from unreliable and degraded water supplies."
