Stream Stability

     The natural stability "blueprint" can only be applied to stream sections of similar form and structure. The form and structure of a stream change when there are changes in stream bed materials, and in stream valley type, slope, shape, pattern and dimension.
     For a stream to be stable it must be able to consistently transport its sediment load, both in size and shape. Natural stream channel stability is achieved by allowing the stream to develop stable dimension and form. Channel instability results in excessive erosion or deposition of soil and stone. Rosgen, 1996, p 1-3.
     Natural streams such as Dutch Hollow Brook seek their own stability. Understanding characteristics of naturally stable portions of Dutch Hollow Brook is necessary if the health of Owasco Lake is to be secured in a cost-effective manner.
     Streams are sensitive indicators of environmental stress, as shown when excess sediment supply into Owasco Lake, and channel adjustments in Dutch Hollow Brook, occur due to deforestation, residential development, flood control, roadwork, crop farming and overgrazing close to the Brook's riparian area.
