<br />The sediment basin should alleviate most ofthe operational problems due to sediment laden waters <br />being delivered to Mexico at Morelos Dam. Phase 2 was completed in April of2001. <br /> <br />The need for completing Phases 3 and 4 of the project is currently being reviewed and studied. <br />The space building and flood control releases experienced during the winters of 1997, 1998, and <br />1999, as well as the natural dynamic nature of the river system, make this review prudent. <br /> <br />Limitrophe Division Below Morelos Dam <br /> <br />The IBWC has initiated the development of an Environmental Impact Statement (EIS) to address the <br />work necessary to develop and undertake a boundary preservation project within the Limitrophe <br />section of the Colorado River. The flood events of 1983 and 1993 have changed the course of the <br />river and deposited approximately 10 million cubic yards of material within the first 5.5 miles of the <br />river below Morelos Dam, affecting the carrying capacity of the river and contributing to higher <br />groundwater levels in the Yuma Valley. The EIS will identify the best U.S .lMexico alternative to be <br />undertaken for the proposed project. <br /> <br />December 13,2002 <br /> <br />21 <br />
