Native fishes have been hit hard by the drought, with 18 species—including many salmon runs—at high risk of extinction if warm, dry conditions persist. But there are actions we can take now to avert what could be the largest loss of native freshwater fish biodiversity since the arrival of Europeans in California.
The state and federal fish agencies entrusted with preventing these extinctions face formidable challenges. The species at risk cover a very large geographic area and in many regions the options for emergency management actions are limited. Additionally, the total amount of funding allocated to managing the environment during this drought is very modest: $66 million, or roughly 2% of total state drought spending. (We showed this in our report What If California’s Drought Continues? in Table 1.)
The California Department of Fish and Wildlife has taken many actions despite limited resources (see this summary), with more than 30 projects underway. But more can—and should—be done now to prepare for continued drought. Here are some suggestions:
- Initiate an emergency conservation hatchery program. This should start with fish at risk of extinction that are not already the focus of intense conservation. These efforts can be as simple as building temporary holding tanks or as elaborate as temporarily converting production hatcheries to rebuild these populations.
- Establish a robust environmental water emergency fund. This would enable fisheries managers to purchase or trade water to maintain adequate flows and water quality for at-risk fish. It could be modeled after projects by The Nature Conservancy and the Natural Resources Conservation Service. These initiatives use temporary water transfers to flood farm fields in key locations to create waterbird habitat. During times of high stress for native fishes—usually due to low flows and high temperatures—strategic investments that temporarily return water to streams can help keep fish healthy.
- Develop a reservoir drought-operations plan. State and federal agencies should conserve cold, fish-friendly flows at strategic reservoirs next summer. A margin of safety should be built into these allocations to address unusually warm conditions and modeling uncertainties, such as those that decimated winter-run Chinook salmon below Shasta Reservoir the past two years.
- Develop a drought biodiversity management plan. The state should harvest the lessons from management successes and failures during this drought to develop this plan. Environmental management will be more efficient and effective if we have a plan in place before a drought that sets priorities for emergency actions intended to improve species’ resilience. We need to start on this now, while the lessons are fresh.
Many more actions can be taken (examples are outlined in California Species of Special Concern). However, it’s essential that some actions be taken now to prepare for continued drought. While it’s tempting to hope that the record El Niño now building in the Pacific will solve our drought problems, the only sure thing about El Niño is that it is not a sure thing.

Proposition 47 helped bring down the prison population by about 8,000 inmates, below the mandated target of 137.5 percent of design capacity (the number of inmates that facilities were designed to house). The target was set by a federal court in 2009 in the wake of lawsuits over prison conditions; at the time, it meant a reduction of almost 40,000 prisoners. The prison population has remained below the target since January 2015. This is a key requirement for the state to regain control of prison health care, which is currently overseen by a court-appointed receiver. The total prison population has dropped by slightly more than 45,000 inmates since it peaked in 2006.
As we noted above, reports of increased crime in a number of cities and counties in 2015 have fueled concerns about the impact of these population reductions. Between January and August, violent crime in Sacramento was up by 24 percent compared to the same months in 2014. In Riverside County, violent crime was up almost 11 percent in the first six months of 2015. In the City of Los Angeles, it was up almost 21 percent in the same time period.

Still, it is instructive to compare the earnings of former students across institutional sectors. The table shows what you would see if you looked up earnings profiles for different types of California colleges. We chose colleges with median earnings that were closest to the median of each sector.
What the scorecards don’t show is that the difference between colleges is far smaller than the difference within colleges. The figure shows the variation in earnings at the same campuses included in the table above. First, note the tremendous overlap: many students who start at community college end up earning more than some students who started at UC and CSU. The difference in median earnings between the typical CSU and the typical UC is approximately $10,000. But the difference between the 25th percentiles and the 75th percentile of UC Davis student earnings is almost $50,000.
