In the last full paragraph on p. 6:

Among the 88 basins examined, revisions to drainage areas were made for 62 basins.  Change 62 basins to 60 basins

The drainage areas listed in a table presented in the subsequent Estimation of Flood Magnitude and Frequency at 
Ungaged Sites section of this report are those used for this study, and revised drainage areas are listed for 
52 of 333 sites in the table (indicated by the asterisk appearing beside the reivsed drainage areas).  Change 
52 of 333 sites to 50 of 333 sites 


Under equation 21 on p. 34:

Vp,P(g)r is the variance of prediction at the gaged station derived from the applicable regional regression 
equations for the selected P-percent chance exceedance (from table 13, p. 96), in log units;  Change 
(from table 13, p. 96) to (from table 9)

VpP(g)s is the variance of prediciton at the gaged station from the log-Pearson Type III analysis 
for the selected P-percent chance exceedance (from table 9), in log units; and  Change (from table 9) 
to (from table 13, p. 96)


Table 7, p. 90:

For 02102908, change drainage area from 7.58* to 7.63


Table 7, p. 94:

For 03450000, change drainage area from 5.5* to 5.46
