In that lower elevation range we assume rainfall dominates the flood <br />hydrology. There is no big difference between the three subbasins in that rainfall-flood <br />elevation range. <br /> <br />DRAINAGE AREA BE1WEEN 11,000' AND 12,000' <br /> <br />The range between 11,000' and 12,000' seems to be a transition zone. Part of that <br />area contributes to snowmelt flooding and part of it seems to be too high and cold to <br />contribute much to snowmelt flooding. In the specific case of the three subbasins of Clear <br />Creek there does not seem to be a clear trend with regard to territory between 11,000' and <br />12,000'. <br /> <br />3 <br />
