Federal government agencies’ responsibilities for national water resources management grew rapidly in the 20th century, along with the budget to execute those responsibilities. In most places today, river flows are the result of rainfall and runoff, as well as the presence of the water development projects of these agencies. Meanwhile in the nation’s watersheds, demands on water resources are changing along with changes in rainfall and runoff volume and patterns, suggesting the possible need for new investments and different management of the investments currently in place. However, by historical standards, there has been a radical reduction in the Federal roles and budgetary commitment to river management. This diminished Federal role has resulted from competing water management visions that I will refer to as “old water conservation,” “new water conservation,” and “watershed restoration.” Old water conservation is where I begin.
Throughout the nation’s first 200 years, engineering works (i.e., infrastructure) were supposed to remove the tails from the hydrograph – that is remove natural variation in river flows – promoting material prosperity and general social well-being. In 1934, the National Resources Planning Board declared1,
In 1963, when dedicating the Whiskeytown Dam on the Trinity River in California, President Kennedy concluded his remarks by endorsing the old water conservation vision, as follows:
A drawing of an ideally managed large river basin in the 1950 Truman administration’s report on water resources has an illustration of the old water conservation. In the upper reaches of the smaller watersheds, cover crops and reforestation on eroded soils slow runoff and control erosion. Downstream, small dams are combined with diversion channels and other conveyance facilities to move water to irrigated farm fields and small communities. Previously wet areas are drained by small ditches leading to larger canals, with the drained land dedicated to cities and farms. On the larger rivers, dams create reservoirs to store water, while levees along the river edges and deepened river channels limit flooding of fertile soils. Cities are located adjacent to flood-protected rivers, and their manufacturing and other commercial facilities along the river edge are served by ports and barge terminals. The water stored in reservoirs irrigates agricultural fields, generates electric power, and provides for other water uses in dry times.
This grand vision of the ideally managed river basin was to be executed by Federal construction of levees, channels, dams, and reservoirs paid for by the Federal taxpayer. The Federal efforts were accompanied by state and local governments building water supply reservoirs, pipes, and open canals and transferring that stored water over long distances. This national investment in advancing the old water conservation vision transformed a natural water supply that
