A Prodedure to Estimate the Response of Aquatic
Systems to Changes in Phosphorus and Nitrogen Inputs
Provides a simple tool to estimate waterbody sensitivity to nutrients.
Useable by field conservationists, partners, and landowners with little
prior educational background, it incorporates educational material that
will raise the awareness and knowledge level of field conservationists.
Management recommendations by type of waterbody are provided along with
general recommendations for subsequent analysis. CITATION: Natural
Resources Conservation Service. 1999. A Procedure to Estimate the
Response of Aquatic systems to Changes in Phosphorus and Nitrogen
Inputs. NRCS West National Technology Support Center, Portland, OR.

Stream Visual Assessment Protocol
Provides a simple procedure to evaluate the condition of a stream based
on visual characteristics. It is designed for use by landowners and
conservationists in the field. The protocol provides an overall
assessment of the condition of the stream and riparian ecosystems,
identifies opportunities to enhance biological value, and conveys
information on how streams function and the importance of protecting or
restoring stream and riparian areas. The assessment can be completed in
15 to 20 minutes and no prior training in biology or hydrology is
required. CITATION: Natural Resources Conservation Service. 1998. Stream
Visual Assessment Protocol. NWCC-TN-99-1. West National Technology Support
Center, Portland, OR

National Handbook of Water Quality Monitoring
Provides information on how to design a monitoring system to observe
changes in chemical water quality associated with agricultural nonpoint
source controls. Part 1 was published in 1997 and covers how to design a
monitoring system. Part 2 is under development and covers the analysis
of data from monitoring. These documents will be published under a new
numbering system. The draft version of Part 2 (now numbered 450
Part 615) is available for review purposes. CITATION: Natural
Resources Conservation Service. 1997. National Handbook of Water Quality
