The State Water Board’s enforcement authority for water right is inconsistent with its broad enforcement authority over water quality matters. The recommendations contained in this report would enhance the ability of the State Water Board to take appropriate enforcement actions over water right matters.

The results of this effort are organized and presented as follows in this Report:
• A review of the Dialogue process that provides additional details about participating
stakeholders and their perspectives;
• A description of the background and challenges for California’s groundwater management and
current efforts to achieve measurable progress toward sustainable management;
• A set of key Findings; and
• A package of seven policy Recommendations intended to lead to a new state policy for meaningful, measurable improvement in groundwater management within realistic timeframes.
The Recommendations in this report reflect the best judgments of CWF about what is needed to achieve sustainable groundwater management while keeping decision making primarily at local and regional levels. CWF remains committed to a constructive public discussion about this critical issue and, ultimately, to meaningful legislative and policy actions.

This study began as an attempt to develop a statewide thematic approach to surveying the ditches and canals which are a commonly encountered, but previously little studied, property type in California. In the past, canals were not always recognized as a type of cultural resource that might need study, and furthermore, although highways and other transportation facilities often intersect artificial waterways, projects that merely cross linear resources typically have little potential to affect them. As a result, structures such as canals, railroads, or roads that were bridged by a transportation project were rarely included in cultural resource studies.
Now there is increased awareness that canals and other water conveyance facilities can be historically significant, and that when projects do have the potential to affect them, they need to be studied systematically. However, important water conveyance systems are frequently extensive and sometimes quite complex, while transportation project effects on them are typically limited to a small segment of the entire property. Under these circumstances, developing a basic historical context would allow researchers to work from a baseline of existing knowledge, thus helping to achieve a suitable balance between the need for adequate information and expenditure of a reasonable level of effort.
Because of California’s unique combination of natural resources, climate, topography, history, and development patterns, the state has a variety and number of water conveyance systems possessed by few if any other states. Consequently, little guidance has been developed at a national or regional level, leaving California to develop its own statewide historic context and methodology. Sufficient research has now been conducted on California’s water conveyance systems to provide this historic context and survey methodology for the appropriate consideration of water conveyance systems, especially the frequently encountered canals and ditches, in order to take into account the effect of transportation projects on historic water conveyance facilities.

In 2014, the California Natural Resources Agency and the U.S. Department of the Interior asked the authors of this paper, as four former leaders of The Delta Science Program, to summarize the challenges faced by water supply and ecological resource managers in this critically important region of Northern California. They concluded that the challenges are so
complex as to meet the definition of a “wicked” problem. Such problems can’t be ignored, defy straightforward characterization, and have no simple solutions. Yet they must be actively managed to maximize
beneficial and minimize adverse outcomes.
In this context, the following paper calls for Delta management to become more nimble and better coordinated.
