Topic	Habitat: Pool Type and Pool Frequency

 

Caption:  The above chart shows both the proportion of pools by pool type and pool habitat frequency by survey length for tributaries of Ten Mile River surveyed in 1995-1996. The proportion of scour pools and backwater pools provides information on pool habitat quality for coho salmon, while the pool frequency (red lines) provides information on pool habitat quantity. To assess the degree to which coho salmon may be limited by pool habitat, both parameters should be considered. For example, Mill Creek pools are 80% scour type, but pools occupy only 10% of the stream habitat thus indicating that pool habitat is a limiting factor. Streams are ordered by basin area. See Info Links for more information.
