Minimum high water damage a. Maintain condition favorable to high egg production a. Control high water levels i Upstream storage ii Pump to the west desert iii Breach the causeway iv Restrict development in the flood plain a. Control the lake level b. Breach the causeway All Changes the nature of the stream Floods and thus eliminates present uses of the land May reduce the TDSa concentration of the north arm brine No aid to establish facilities Create a specific habitat which may affect the ecosystem M. E. Industries Brine Shrimp May alter the TDSa concentration of M. E. Industries both the north and south arms. Economic and physical feasibility of each alternative social, economic, and environmental effects of alternative. Effect on the TDSa concentration in each arm. Would breaching the causeway produce conditions favorable for egg production? A. Boating 1. Easy access aTDS is total dissolved solids. a. Road construction b. Breach the causeway Easy access to bird rookeries in the north arm may be detrimental to the birds Wildlife Effect of human intrusion on nesting birds |
