Summary of LWD count for three reaches of the upper Blackfoot River. Of 473 total pools, we measured 134 pools over the entire survey reach (Table 5). Pool frequency decreased in the downstream direction from ' (upper reach), to ' (middle reach), to ' in the lower reach. In the upper reach, 73 of 293 pools were measured, of which 68% (N= 50) contained LWD. For the middle reach, 69% (34 of 49) of measured pools contained LWD compared with 42% (5 of 12) pools in the lower reach. For measured pools with LWD, the percent of pool cover formed from wood decreased on the downstream direction from 12% (range ) in the
