The main change to the river from the flood was loss of mobile, midstream gravel bars. The high flow carried the gravel down to manmade collection points (flow restriction) above the weirs. Since the Bow is entirely dam controlled, no new gravel can enter the system from upstream to replenish the bars. The only source of gravel, other than the Highwood, is cannibalizing the banks. The river is permanently wider and shallower with a fixed, boulder streambed instead of a mobile gravel bed. This could result in more mud deposited in some areas.Bug habitat changed.
