increase from previous decades due to regeneration was accounted tior by using the bU year <br />? recovery cuive developed on the Fi•aser Experimental Forest (Troendle and King. 1)85). <br />Data and spreadsheets in the pi•oject tile show data used to calculate the average water yield <br />increase by timber type, aspect, and harvest type. The resulting average water yield increase per <br />acre (Water yield increase 1, page 13) was then tied to the FORPLAN solution to determine the <br />total annual water yield increase for the Routt National Forest in acre-feec by alternative. The <br />FORPLAN solution also projected the probable acres harvested within each watershed. These <br />projections were used to estimate the water yield increase in the major river basins (Attachment <br />2) for the tirst tive decades (page 14). <br />A general interpretation was made regarding water yield increases due to timber harvest relative <br />to baseline water yield (Attachment 3). <br />REFERENCES <br />Borland. 1993: Quattro Pro Version 5.0 for Winciows.
