Fred Greaves \/ California Department of Water Resources<\/p>\n<p>\u201cThis year\u2019s severe storms and flooding is the latest example that California\u2019s climate is becoming more extreme,\u201d said DWR Director Karla Nemeth. \u201cAfter the driest three years on record and devastating drought impacts to communities across the state, DWR has rapidly shifted to flood response and forecasting for the upcoming snowmelt. We have provided flood assistance to many communities who just a few months ago were facing severe drought impacts.\u201d<\/p>\n<p>Just as the drought years demonstrated that California\u2019s water system is facing new climate challenges, this year is showing how the state\u2019s flood infrastructure will continue to face climate-driven challenges\u00a0for moving and storing as much of these flood water as possible.<\/p>\n<p>This year\u2019s April 1 result from the\u00a0<a href=\"https:\/\/cdec.water.ca.gov\/snowapp\/sweq.action\">statewide snow sensor network<\/a>\u00a0is higher than any other reading since the snow sensor network was established in the mid-1980s. Before the network was established, the\u00a0<a href=\"https:\/\/cdec.water.ca.gov\/reportapp\/javareports?name=COURSES.198304\">1983 April 1 statewide summary<\/a>\u00a0from manual snow course measurements was 227 percent of average. The\u00a0<a href=\"https:\/\/cdec.water.ca.gov\/reportapp\/javareports?name=COURSES.195204\">1952 April 1 statewide summary<\/a>\u00a0for snow course measurements was 237 percent of average.<\/p>\n<p>\u201cThis year\u2019s result will go down as one of the largest snowpack years on record in California,\u201d said Sean de Guzman, manager of DWR\u2019s Snow Surveys and Water Supply Forecasting Unit. \u201cWhile 1952\u2019s snow course measurements showed a similar result, there were fewer snow courses at that time, making it difficult to compare to today\u2019s results. Because additional snow courses were added over the years, it is difficult to compare results accurately across the decades with precision, but this year\u2019s snowpack is definitely one of the biggest the state has seen since the 1950s.\u201d<\/p>\n<p>For California\u2019s snow course measurements, only 1952, 1969 and 1983 recorded statewide results above 200 percent of the April 1 average. While above average across the state this year, snowpack varies considerably by region. The Southern Sierra snowpack is currently 300 percent of its April 1 average and the Central Sierra is at 237 percent of its April 1 average. However, the critical Northern Sierra, where the state\u2019s largest surface water reservoirs are located, is at 192 percent of its April 1 average.<\/p>\n<p>The size and distribution of this year\u2019s snowpack is also posing severe flood risk to areas of the state, especially the Southern San Joaquin Valley. DWR\u2019s State-Federal Flood Operations Center (FOC) is supporting emergency response in the Tulare Lake Basin and Lower San Joaquin River by providing flood fight specialists to support ongoing flood response activities and by providing longer-term advanced planning activities. The FOC and DWR\u2019s Snow Surveys and Water Supply Forecasting Unit are helping local agencies plan for the spring snowmelt season by providing hydraulic and hydrologic modeling and snowmelt forecasts specific to the Tulare Lake Basin that are informed by DWR\u2019s snowmelt forecasting tools, including\u00a0<a href=\"https:\/\/www.youtube.com\/watch?v=P3TqKA4Ebl8\">Airborne Snow Observatory (ASO)<\/a>\u00a0surveys.<\/p>\n<p>Storms this year have caused impacts across the state including flooding in the community of Pajaro and communities in Sacramento, Tulare, and Merced counties. The FOC has helped Californians by providing over 1.4 million sandbags, over 1 million square feet of plastic sheeting, and over 9,000 feet of reinforcing muscle wall, across the state since January.<\/p>\n<p>On March 24, DWR\u00a0<a href=\"https:\/\/water.ca.gov\/News\/News-Releases\/2023\/March-23\/Harnessing-Series-of-Winter-Storms-California-Increases-State-Water-Project-Allocation\">announced an increase<\/a>\u00a0in the forecasted State Water Project (SWP) deliveries to 75 percent, up from 35 percent announced in February, due to the improvement in the state\u2019s water supplies. Governor Newsom has\u00a0<a href=\"https:\/\/www.gov.ca.gov\/2023\/03\/24\/governor-newsom-eases-drought-restrictions\/\">rolled back some drought emergency provisions<\/a>\u00a0that are no longer needed due to improved water conditions, while maintaining other measures that continue building up long-term water resilience and that support regions and communities still facing water supply challenges.<\/p>\n<p>While winter storms have helped the snowpack and reservoirs, groundwater basins are much slower to recover.\u00a0Many rural areas are still experiencing water supply challenges, especially communities that rely on groundwater supplies which have been depleted due to prolonged drought. Long-term drought conditions in the Colorado River Basin will also continue to impact the water supply for millions of Californians. The state continues to encourage Californians to\u00a0<a href=\"http:\/\/www.saveourwater.com\/\">make water conservation a way of life<\/a>\u00a0as more swings between wet and dry conditions will continue in the future.<\/p>\n<p>DWR conducts five media-oriented snow surveys at Phillips Station each winter near the first of each month, January through April and, if necessary, May. Given the size of this year\u2019s snowpack with more snow in the forecast, DWR anticipates conducting a May snow survey at Phillips Station. That is tentatively scheduled for May 1.<\/p>\n<p>Additional Resources<\/p>\n<ul>\n<li><a href=\"https:\/\/www.youtube.com\/@calwater\/videos\">Video of today\u2019s Phillips survey<\/a><\/li>\n<li><a href=\"https:\/\/pixel-ca-dwr.photoshelter.com\/galleries\/C0000v.QyV7hLl.E\/G0000DTiV2EFxqEY\/Snow-Survey-April-2023\">Digital photos<\/a>\u00a0of today\u2019s Phillips survey<\/li>\n<li><a href=\"https:\/\/cadwr.box.com\/s\/c1sw2vykonz083c3joubza2k0wlloqex\">B-roll<\/a>\u00a0of today\u2019s Phillips survey<\/li>\n<li><a href=\"https:\/\/cdec.water.ca.gov\/snow\/current\/snow\/index.html\">Snowpack readings\u00a0<\/a>(View readings for\u00a0<a href=\"https:\/\/cdec.water.ca.gov\/reportapp\/javareports?name=swccond.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">current regional snowpack<\/a>\u00a0and\u00a0<a href=\"https:\/\/cdec.water.ca.gov\/reportapp\/javareports?name=PLOT_SWC.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">historical snowpack comparison<\/a>)<\/li>\n<li><a href=\"https:\/\/cdec.water.ca.gov\/snow_rain.html\">Precipitation data\u00a0<\/a>(View current California Data Exchange Center charts for the\u00a0<a href=\"https:\/\/cdec.water.ca.gov\/reportapp\/javareports?name=TAB_ESI.pdf\">Northern Sierra 8-station index<\/a>\u00a0for updated rainfall readings in the critical northern portion of the state, as well as the\u00a0\u00a0<a href=\"https:\/\/cdec.water.ca.gov\/reportapp\/javareports?name=TAB_FSI.pdf\">San Joaquin 5-station index\u00a0<\/a>and\u00a0<a href=\"https:\/\/cdec.water.ca.gov\/reportapp\/javareports?name=TAB_TSI.pdf\">Tulare Basin 6-station index<\/a>)<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>###<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Phillips Station, CA&#8230;The Department of Water Resources (DWR) today conducted the fourth snow survey of the season at Phillips Station.
