to the various municipalities new data on lake levels <br />that are graphed. A copy is enclosed. Two things <br />should be noted: <br />1) The date axis (x axis) is non linear. This <br />tends to distort the d:-ata a bit. <br />2) On the 5th of January, 1988 the zero elevation <br />for the lake gauge was adjusteJ down 0.22 feet. <br />This effects the )raph in that comparison of data <br />is made mere difficult. since the baseline has <br />shifted without a correction made to all data. <br />1 am enclosing a graph that I developed usinq the same <br />data readjusted to 1987 gauge sittings (the preferred <br />way would be to readjust 1987 to 1988 gauge settings). <br />I hope to complete the grap`, with the latest data, and <br />I will send a copy to yoc. when completed. <br />In reviewing tha data Lwo dates immediately jump out, <br />14--16 July and 24-26 August 1907. The rate of lake <br />level reduction during these periods exceed any other <br />period; .03 feet/oay and .035 feet/day respectively. <br />The dffuct of lake level change is minimal compared to <br />the overall; but, it is cur-ous that these two dates <br />c,ccur before the Aquatennial and State Fair rious <br />because there were rumors that the dam w. jened <br />during these times to allow water to flow „.er the <br />Falls. <br />It should be noted that there his been a rumor in the <br />Orono area that the dam was opened just prior to a <br />visit by a Japanese deleaation in the spring of this <br />year. I tend to discount these rumors as just that and <br />to explain away the increased rate during the <br />beforementioned periods as ca, ^d by natural phenomena. <br />I am interested though in to ng at the new data lust <br />to satisfy myself that the coincidences are lust <br />that. <br />I would suggest tte following for the future. <br />1. Keep the public aware of lake levels and <br />causes of increases and decreases.
