compared to the other available information sources, the data at Station 06746000 <br />displayed the following characteristics: <br />• The longest period of record, <br />• The most complete set of data prior to and throughout the period of study, <br />• Corresponding monthly and daily diversion data available, and <br />• Continues to be operated as a recording device through present. <br /> Figure 2 <br /> Michigan Ditch <br /> Historic Diversions 1950 - 2002 <br />~,ooo .. <br />6,000 -~-~ r ~-~-~-~ -~,-~-~--~,-~-~-~ r--~-~-~ ~ ~-~-~-~ r~,-~-~-~ ~-~-~ <br />s,ooo - <br /> <br />w ~~~~~ ~~~~ ~~~~~~ ~~~~~~~~~~ <br />4,000 r~~-~_~ _~~-~-~+~-~-~-~+~-~-~r~~-~-~~~ <br />o <br />~~~~~ ~~~~ ~~~~~~ ~~~~~ ~~~~ <br />3,000 - r r r- i- r - r te -i - r- r r -i - r r r- r- i- r I. <br />i i i i i i t <br />~ i i i i i <br />2,000 <br />1,000 <br />0 <br />a <br /> <br />~n ~n ~n ~n ~n m a a a a <br />~ ~ ~ ~ ~ <br />m m m m m m m m m ~ ~ ~ ~ ~ 0 0 <br />o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ o~ 0 0 <br /> Year <br />Annual Diversions for the 1950 to 2002 study period: <br />Average (1950-2002) = 1,910 acre-feet <br />Maximum (1997) = 6,381 acre-feet <br />Minimum (various years) = 0.0 acre-feet. <br />It should be noted that between 1954 and 1986, the ditch was not fully utilized because of <br />disrepair or work being performed on the ditch. Therefore, the diversion records for this <br />period do not reflect long-term historic diversions. As such, future modeling conditions <br />should be basin on the data from before 1954 and after 1986. The preceding data is <br />presented in water year due to the availability of data at the time this report was prepared. <br />If this data is used for future modeling efforts, it is recommended that the data be <br />analyzed in calendar year. Monthly diversions for Michigan Ditch are presented in Table <br />2. <br />MichiganDitch.doc 5 of 9 <br />
