From years 2002 to 2026, the Hydrology. The probability and magnitude of magnitude of excess flows to Mexico. probability of excess flows varies from 20 to 25 excess flows to Mexico is similar but occasionally percent. After 2030, the probability of flood flows higher under the IA. decreases to 10 to 15 percent. The magnitude of flood flows varies from 0 to over 6 MAF, with large flood flows (over 250 KAF) anticipated approximately 20 percent of the time and flood flows over 1 MAF less than 15 percent of lime. TRANSBOUNDARY IMPACTS Potential impacts to habitat and species in Biological Resources. It is anticipated that flood Biological Resources. The fA would result in a flood Mexico. flow frequency and quantities would be reduced as flow probability and magnitude that are generally additional water is used by the Upper Division equallo, or some~hat greater than, the No-Action States. This may result in some reduction of Alternative. Therefore, this action would have no wildlife habitat through the reduction in flows potent.ial impact on any federally listed species in reaching the Delta area. It is expected, however, Mexico. that much of the existing habitat would remain as it is since most of the riparian habitat is composed of salt cedar, which would be fed by groundwater. No measurable impact is expected to sensitive marine species. tT1 'f' w " ~ '" II - ;. '" ~ 3 :l " ~
