Long term drought impacts continued to ease through the month of April, with precipitation more than double normal levels for the northern Sierra. This continued the very wet pattern which began in the Fall and continued through the winter months to produce a deep snow-pack and to fill reservoirs. The northern Sierra broke the record  for the wettest year on record, with records dating back to 1920-21. At the end of April, Lake Shasta was 109% of normal, Lake Oroville was 91%, Folsom Lake was 99%, and Don Pedro was 110%. New Melones Reservoir improved most significantly and was at 133% of normal, reaching levels not seen in years.
The U.S. Drought Monitor showed all of interior Northern California in the 'None' category for April, with no areas in drought or abnormally dry.
Groundwater aquifers continued to recharge, with the DWR Water Data Library showing strong signs of improvement in many areas.
Governor Jerry Brown had declared a drought emergency for the entire state of California on January 17, 2014. On April 7, 2017, the governor made a new declaration ending the drought emergency for all but a few counties in California. Tuolumne County is the one county in interior northern California which remained in a drought emergency, with emergency drinking water projects continuing to help address diminished groundwater supplies. A local emergency proclamation remains for Tuolumne County to coordinate response to the drought.
The State Water Resources Control Board will maintain urban water use reporting requirements and prohibitions on wasteful practices such as watering during or after rainfall, hosing off sidewalks and irrigating ornamental turf on public street medians.
State agencies issued a plan to continue to make conservation a way of life in California, as directed by Governor Brown in May 2016. The framework requires new legislation to establish long-term water conservation measures and improved planning for more frequent and severe droughts.
The state will continue its work to coordinate a statewide response on the unprecedented bark beetle outbreak in drought-stressed forests that has killed millions of trees across California. The threat of dead or dying trees continued, with on-going tree-removal programs at the state and federal level.
The state continued to supply food assistance to those impacted by the drought, along with California Disaster Assistance Act money for those who have lost drinking water due to dry wells.
