About the Program

The purpose of the Wetland Assessment Procedure (WAP) is to characterize the ongoing biological condition and health of wetlands by collecting information on vegetation, hydrology, soils, and other pertinent variables in monitored wetlands to accurately characterize the ongoing biological condition and health of each wetland.

The WAP was developed from data collection and analysis performed during 2000-2002 and 2004. The current method was finalized in 2005.

Program Goals

This information will be used for a variety of water management purposes, including wellfield management considerations, the development of minimum flows and levels, and the assessment of recovery in areas that have experienced historic hydrologic and biologic impacts due to groundwater withdrawals. Although the WAP seeks to document and monitor many aspects of wetland health, some of these aspects are not the procedure's focus. Many wetlands also are subject to negative health impacts caused by surrounding land management and drainage practices, encroaching development, cattle operations, exotic plant species introduction, disease, and other variables.  However, the WAP attempts to focus on the collection of data that will be used to assess biologic changes caused by the hydrologic effects of groundwater withdrawals.

The District provides WAP training annually in April. Details on the location and exact dates will be listed when determined.

Program Documents

Below are the most recent documents needed to apply the WAP in the current year. These documents should be reviewed prior to training, and prior to performing WAPs.
