Groups solved their commons problem only once they shared one picture of it. In the West Basin, an engineer's report gave the parties "a single, authoritative image of the problem", and published pumping figures made information approximate "common knowledge"; elsewhere a state report denying overdraft held change back. Groups without a shared image, a way to split the problem into parts, or respect for one another's interests fail "even when the institutional means to do so are available to them". For agents, a shared, checkable record of the collective's state is a precondition of self-governance, not a convenience.

  Given the different technologies in use, any rules that were defined to limit use would tend to benefit one subgroup over another, rather than benefit all in a similar manner.

  Individuals who do not have similar images of the problems they face, who do not work out mechanisms to disaggregate complex problems into subparts, and who do not recognize the legitimacy of diverse interests, are unlikely to solve their problems, even when the institutional means to do so are available to them.

  In 1964, for example, the California Department of Water Resources published a report that denied the existence of overdraft conditions in two of the large sub basins
