The Northern California Water Association (NCWA) invites you to read Preparing for Drought.

Droughts are an increasingly challenging part of water management in California, and droughts have a significant effect on the Sacramento Valley. As part of our ongoing efforts to prepare for dry conditions, the NCWA Board of Directors and water resource managers throughout the region convened earlier this year. The themes and recommendations that follow were presented in these meetings. Please see the attached document.Click Here

STWEC Board and Staff Present to the Regional Board - October 14, 2016

STWEC and fellow northern Sacramento Valley sub-watershed coalitions presented to the Central Valley Regional Water Quality Control Board (Regional Board) during the October 14th meeting held in Redding. ​The goals of the presentation were to highlight for the Regional Board that surface and groundwater quality conditions are very different in the upper watersheds because of the stewardship that is taking place, and to appeal to the Regional Board to change the requirement that any area is deemed high vulnerability (HVA) just because it has a management plan.  
View the PowerPoint presentation given by the following; Pam Giacomini (Hat Creek), UC Cooperative Extension Advisor Larry Forero, Resource Conservation District of Tehama County Manager Vicky Dawley, NeCWA Board President Ted de Braga, NeCWA Watershed Coordinator Tami Humphry, and NCWA Director of Regulatory Affairs Bruce Houdesheldt. The Regional Board was receptive to the presentation with staff indicating further discussions should take place.

Nitrogen Management Plan Worksheet (NMP)

The California Fertilization Guidelines for tree and field crops is based on research by FREP, CDFA and UC Davis.

A tool for estimating the amount of nitrogen, phosphorus, and potassium that is removed by the harvest of agricultural crops is available through the USDAs Nutrient Content of Crops Calculator. This resource corresponds with the Post Production Actuals, item 13 N Removed on the NMP Worksheet. 

Fertilizers and Nutrient Sources Fact Sheet is available for brief information about the production, agricultural use, management practices, and chemical properties of common synthetic fertilizer materials.  

Wellhead Protection Guide

Detailed information regarding the “Good Housekeeping" Practices option listed under wellhead protection on the Farm Evaluation is available in the Guide for Private Domestic Well Owners.
