<br />The USBR has completed 21 of the allowed 35 wells on the united
<br />States side within eight kilometers (five miles) of the Arizona-
<br />Sonora boundary near San Luis for protective and regulatory pump-
<br />ing, and 13 of the 21 wells were pumped in 1993. The remaining 14
<br />allowed wells have been deferred until water supply needs make
<br />construction necessary.
<br />
<br />The United States pumped from domestic, municipal, and irrigation
<br />wells located within eight kilometers (five miles) of the boundary
<br />near San Luis the following quantities:

<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.
