Seasonal Peak Snow Predictability Derived From Early-Season Snow in North America

American Geophysical Union (AGU) | September 12th, 2023

Early season snow observations show promise in predicting peak snow water equivalent in locations where large-scale ocean-atmosphere patterns similarly influence fall and

Early season snow observations show promise in predicting peak snow water equivalent in locations where large-scale ocean-atmosphere patterns similarly influence fall and winter conditions, and in northern maritime locations where winter temperatures are warm enough that rain on snow and midwinter melt occur.

Second Amended Delano-Earlimart Irrigation District Groundwater Sustainability Plan 2024

Delano-Earlimart Irrigation District Groundwater Sustainability Agency (DEID GSA) | July 1st, 2024

In January of 2020, the DEID GSA submitted its Groundwater Sustainability Plan (GSP) to the California Department of Water Resources (DWR). The GSP provided technical documentation of the DEID Management Area’s existing sustainability, along with addressing the needs of the Earlimart Public Utility District and Richgrove Community Services District. The GSP outlined specific management actions that will be taken in accordance with the Sustainable Groundwater Management Act. DWR’s review of the Tule Subbasin, as a whole, resulted in an incomplete determination, to which the GSAs in the Tule Subbasin had 180 days to respond. The GSA’s in the Tule Subbasin provided revised GSPs on July 27, 2022, which DWR also determined were inadequate, causing the Tule Subbasin to transition to the oversight of the State Water Resources Control Board (SWRCB). The draft GSP found below includes updates to specifically address comments received from the SWRCB and their staff in anticipation of the Tule Subbasin probationary hearing on September 17, 2024. Comments on the 2nd amended GSP can be submitted to info@deid.org and will be accepted through August 18, 2024. Due to size, this file has been divided.

Sierra Nevada Regional Report - California’s Fourth Climate Change Assessment

California Natural Resources Agency (CNRA) | August 16th, 2018

The Sierra Nevada region is critical to the environment and economy of California. Its places and peoples provide essential natural resources including fresh wate

The Sierra Nevada region is critical to the environment and economy of California. Its places and peoples provide essential natural resources including fresh water, clean power, working lands, and famous wilderness. The region encompasses tremendous geographical, climatological, and ecological diversity that spans majestic mountains to deep desert basins. The climate consists of cool, wet winters and warm, dry summers with large differences due to latitude (e.g., the southern Sierra is snowier than northern Sierra) and topography (e.g., the Westside is wetter than the Eastside). Variability is another notable feature of the climate with the region experiencing some of the largest year-to-year climatic fluctuations in the United States. Herein we summarize our assessment of climate-change vulnerabilities and adaptation actions in the region.
