Spener

In an email to the news organizations, Spener said that the agency accepted the report's findings, which showed a far greater impact on the flow of the Rio Grande than the builder had claimed.

Sally Spener, a spokesperson for the IBWC, denied that Fisher was able to counter the conclusions in the Arcadis report to the agency's satisfaction.

Sally Spener, the U.S. foreign affairs officer on the International Boundary and Water Commission in El Paso, called the current protests “unfortunate.”

“That’s a lot of water to make up in a short period of time,” said Sally Spener, spokeswoman for the U.S. section of the commission.

The treaty, Spener noted, does not specify sanctions for noncompliance and assumes that both parties will make “good-faith efforts” to fulfill mutual obligations.
