This information paper documents the methods and procedures used in the construction
of probability criteria curves. Weighted criteria are used to assess the impacts
of altered streamflow regimes on a°stream habitat. .They are developed primarily
for those habitat parameters most closely related to stream hydraulics: depth,
velocity, substrate, and temperature. Guidelines for data collection, analysis
and curve development are discussed.
