Technical Services Section
Stream Probabilistic Monitoring Program
The Stream Probabilistic Monitoring Program is the newest program administered
by the Technical Services Section. This program assesses water chemistry using methodology of the
Stream Chemistry Monitoring Program and evaluates the aquatic macroinvertebrate
assemblage using the approach of the Stream Biological Monitoring Program.
Physical habitat data (for example stream channel substrate, bank condition) also are collected and
used to augment the chemical and biological data. The unique aspect of this program is the method in
which sample locations are selected. The SPMP does not rely on repeated sampling of a fixed set of
hand-selected monitoring sites. Instead, sampling points are selected randomly from the network of
all classified streams in the state, and a new set of sites is sampled each year. The survey design,
which has been developed by the
EPA Research Division and promoted nationwide, is a method that can be used to
generate a statistically unbiased estimate of the conditions of any resource. This program will
especially complement the two established stream monitoring programs by improving our knowledge of
conditions in smaller lotic systems.
