In English, the observed flow of the Bear River at Harer, Idaho is
regulated or affected by the change in storage at Woodruff Narrows
Reservoir, the diversion of flow by Chapman Canal, and the change in storage
at Sulphur Creek Reservoir. When reservoirs are filling (storing water),
the adjustment made on the downstream point is positive (i.e., the flow at
Harer would have been higher if not for the reservoir). Conversely, when
reservoirs are being tapped or drained for use, the adjustment on the
downstream point is negative (i.e., the flow at Harer would have been lower
at this time of the year if not for the reservoir). Diversions may also be
negative adjustments, as in cases where water is diverted into the basin
from an adjacent watershed. In this example with Harer, the diversion
adjustment is positive.
