SRWP Monitoring Data is Online


The SRWP monitoring data from 1998 - 2001 is available online at the Calif. Dept. of Water Resources Bay-Delta Tributaries. This website was launched in February 2004 and is continuing to be improved and expanded. SRWP data is summarized here and is available for download here.

SRWP Water Quality Compendium

Contents of the Compendium

The information in the compendium is presented as three primary sets of information:

Program metadata, including contact information, primary program objectives, sampling frequency and strategy, monitoring period, and site selection basis. If provided, monitoring program reference documents (monitoring plan and QAPP) are also listed.

Summaries of the parameters monitored by each program.

Summaries of the sites monitored by each program. Additionally, monitoring locations are presented in site maps and identified by program.

The following criteria were used to identify major monitoring programs appropriate for inclusion in this compendium update:

  • Monitoring locations must be in the Sacramento River watershed.
  • Media monitored must include one of the following: water, sediment, aquatic species tissue or biota, aquatic communities, or physical habitat.
  • Parameters monitored must include one of the following: chemical analytes; physical parameters; toxicity; flow; fish, algal, or benthic invertebrate abundance and community metrics; or physical habitat measures.
  • QA and monitoring tools must be generally adequate to produce comparable and defensible data

“Major” monitoring programs were defined as those expected to monitor for a period of at least 1 year, with a minimum frequency of four events/year for water column sampling with no minimum for sediment, bioassessment, or tissue monitoring. Major programs were also defined as including three or more surface water locations in the Sacramento River watershed. It is recognized that these criteria will necessarily exclude some potentially significant monitoring programs, including a number of watershed group monitoring programs. This is an unavoidable limitation of this effort imposed by the realities of the cost in time and funding to compile this information. Additionally, although information for the individual programs was accurate when included in this compendium, many programs adjust their scope and objectives annually. Therefore, users of this information should verify the specifics of current monitoring programs with the contacts listed in the Metadata.
