The importance of fluvial forces shaping the physical attributes of Laurel Creek, as a surrogate for other small meandering streams in southern Ontario, was recognized during this presentation. Laurel Creek was assessed using the theoretical approach outlined by Leopold et al. (1964) to identify that a dynamic equilibrium exists between a stream and its valley
Stream modifications (impoundment, redirection, channelization, riparian vegetation removal, and stormwater runoff) evident in Laurel Creek was related to altered channel shape, homogenous substrate composition, controlled flows, reduced water quality, eutrophication, and the decline of the suitability of this environment to support a diverse suite of aquatic life using understanding provided from Hynes (1970)
It was stressed that this an often over-looked aspect of stream management and these tenets must be understood before effective rehabilitation or other ameliorative measures may be successfully completed on small streams.
