Rocky Broad

The usgs gage Cove Ck near Lake Lure should be a gage of interest. The cfs/sq. mi ratios are the same as the Rocky Broad according to usgs archival data. Furthermore the Cove Ck gage adjoins the Rocky Broad and has the same drainage basin size of the lower Rocky Broad or about 79 sq. mi. with and average output of about 139 cfs. The upper Rocky Broad drainage is much smaller or about 40 sq. mi.. 200 cfs for the lower RB and 300 for upper should work. It is no more of a leap to use Cove Ck for the Rocky Broad as it is the use Ivy River gage for Big Laurel Ck.
