<br />The Commission is continuing, under Minute No. 242, its program for
<br />exchange of ground-water data for the major ground-water basins
<br />lying partly in the united States and partly in Mexico inclUding
<br />the Colorado River delta area. The objective of the exchange is to
<br />make available hydrologic, geOlogic and water quality data in
<br />either country, to both sections of the Commission to enable evalu-
<br />ation of international ground-water basins conditions.
<br />
<br />New Developments in Region
<br />Point 6 of Minute No. 242 provides that:
<br />
<br />"...The United States and Mexico shall consult with
<br />each other prior to undertaking any new developments
<br />of either the surface or the groundwater resources,
<br />or undertaking substantial modifications of present
<br />developments, in its territory in the border area
<br />that might adversely affect the other country."
<br />
<br />* Minute No. 242 Field was constructed in 1978
