II No signi- ficant change in dissolved mineral content. The stabili- zation of river flowS will tend to decrease pesticide concentrations during periods of historic low flow. High probability for eutro- phication and associated algal blooms. Slight potential for stratification and low D.O.. in deeper waters. 10,988 acres of irrigated crop- land would be requ.ired for the project, the project would impound water for irrigating 287,070 acres of land.
