Land Treatment and Management Irreversible losses of the Region's land resources must be minimized to preserve a freedom of choice for future resource users. Esthetic and environmental factors were of primary consideration in development of the program. Ideally, the land treatment and management program should har- monize with all water and related land resource development programs required to satisfy present and projected demands within the Region. On an equivalent acreage basis, as of 1965, a total of nearly 7 million acres of cropland, forest land, rangeland, and urban and other lands had received adequate treatment. The program includes treatment of an additional 64 million acres by 2020. In most cases, the same acre will require treat- ment more than once during the study period because of development of improved methods, or the limited life of the measure or practice installed. Flood Control The Region is subject to severe and sudden floods, with some flood damage occurring every year. Almost all land suitable for general devel- opment is subject to some degree of flood damage, either from a defined stream or overland flow. The average annual flood damages were estimated at $4l million for 1965 economic and project conditions. With no addi- tional flood control measures after 1965, annual flood damages of $310 million are estimated by the year 2020. Implementation of the flood |
