<br />unsettled and rainy weather) continued to be a source of wasted water.
<br />Listed below is a monthly tabulation in acre-feet for calendar year
<br />1981 showing the water ordered but not taken by United States users
<br />snd the disposition of the water. The water ordered but not taken for
<br />calendar year 1981 was approximately 6,605 acre-feet more than

<br />The overdelivery to Mexico for calendar year 1981 was
<br />342,478 acre-feet. This includes 31,216 acre-feet charged to
<br />United States users not taking water ordered on the master schedule
<br />which could not be retained in storage or taken by others.
<br />
<br />The remaining 311 ,262 acre-feet resulted from anticipatory releases
<br />for flood control and Gila River bank storage returns during the early
<br />part of the year and regulatory waste occurring below Imperial Dam.
<br />In addition, Mexico's minimum order during the entire month of January
<br />was partly the cause of the need for dilution water for salinity
<br />control purposes.
<br />
<br />Flows and diversions for the principal points listed on the master
<br />schedule are shown on Table No. 1 and Chart No.1. These are
<br />provisional records and are subject to revision. Table No. 2 shows
