As California descends deeper into drought, state regulators are planning to do something they’ve done few times in modern history: order thousands of people, farms, and even cities and towns that hold historic water rights to stop drawing water from the rivers, lakes and ponds they rely on. The move is intended to make sure the dwindling flows in California’s waterways are reserved for those with the most senior water rights, as well as for fish and other wildlife.
Many of those with lesser rights would have to turn to storage, groundwater or another source, if they have it. The problem, besides leaving several in a tough spot, is that the state doesn’t have an accurate tally of how much water is being pulled from its watersheds, nor who exactly is taking it.
