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.

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.
