“(2) examine the current and proposed Federal programs affecting such States and recommend to the President whether they should be continued or adopted and, if so, how they should be managed for the next twenty years, including the possible reorganization or consolidation of the current water resources development and management agencies;
“(3) review the problems of rural communities relating to water supply, potable water treatment, and wastewater treatment;
“(4) review the need and opportunities for additional storage or other arrangements to augment existing water supplies including, but not limited to, conservation;
