<br />~ <br />.+:>0 <br />t- <br />oo <br /> <br />A regression line was developed for the data from each <br />station, and various statistical tests were performed to <br /> <br />determine reliability of the relationships. <br /> <br />A complete <br /> <br />report on the process used, and including the 13 preliminary <br /> <br /> <br />relationships will be presented to the Forum for approval <br /> <br />in late 1979. <br /> <br />Figure 1 shows the salt-flow relationship developed for <br /> <br /> <br />one station, and the data points used to develop the relation- <br /> <br /> <br />ship. Figure 2 shows the same relationship, a two-standard <br /> <br /> <br />deviation bandl/, and additional annual data points collected <br /> <br /> <br />since 1972. <br /> <br />The two-standard deviation band is obviously very wide. <br />This is because a large part of the variation in salt load <br />cannot be explained by variations in streamflow alone. As <br />yet, there is no practical method of accounting for all <br />factors affecting salinity. <br />Public Involvement and Participation <br />The Forum and the states have provided for public invol- <br /> <br />ment in the standards revision process. <br /> <br />The Forum held two public meetings on November 14, 1978 <br />in Las Vegas, Nevada, and on November 19, 1978 in Grand Junc- <br />tion, Colorado, to receive comments on the "1978 Revision - <br /> <br />1/ <br /> <br />When the aggregated salt-flow data for a gi ven year <br />results in a data point which falls outside the two- <br />standard deviation band, there is a 95 percent prob- <br />ability that the change did not result by chance. <br /> <br />27 <br /> <br />, <br /> <br />.!; "" <br />
