<br />The Commission is continuing, under Minute No. 242, its program for exchange
<br />of groundwater data for the major groundwater basins lying partly in the
<br />United States and partly in Mexico including the Colorado River delta area.
<br />The objective of the exchange is to make available hydrologic, geologic and
<br />water quality data in either country, to both Sections of the Commission to
<br />enable evaluation of international ground water basins conditions.
<br />

<br />affect the other country."
