A scatterplot of the Bluffflows versus the <br />Archuleta flows is shown in Figure I, together with a smooth of the data using lowess (locally <br />weighted regression over a moving window using 213m of the data). The smooth is essentially a <br />straight line as expected from the high correlation. Given the similarity of these series, subsequent <br />results will be shown for only one of them (Archuleta), unless the other site clearly shows a <br />different behavior. <br /> <br /> ~ <br /> . <br /> ~ <br /> ~ <br />;< ~ <br />~ <br />0 i'o <br />u: <br />'" <br />=> <br />10 <br /> ~ <br /> :,. <br /> <br /> <br /><=> <br /> <br />o <br /> <br />200000 <br /> <br />400000 <br /> <br />600000 <br /> <br />800000 <br /> <br />Archuleta Flow <br /> <br />, . <br />Figure 1: Scatterplot of San Juan Monthly Streamflow at Bluffvs. Streamflow at Archuleta.
