The total of the developed primary power in the State is 900 horse power, which is .5 per cent of the total estimated available primary power. The total of the developed secondary hydro-electric power in the State at the present time is 6,320, which is 4 per cent of the estimated available secondary power. Plans for the development of the water power of White River and its tributaries have been considered for many years, but as yet only preliminary developments have taken place. Four of these projects have an estimated total horse power of 147,000. The above map shows the locations of the stream gaging stations in Arkansas, most of which have been maintained over considerable periods of time. These stations have been established on the rivers for the purpose of determining the average quantity of water flowing throughout the year. From this information the available water power over a period of time may be calculated. The U. S. Geological Survey has maintained seven stations on the White River basin in Arkansas and nine on the same basin in Missouri. It has also maintained three on the Ouachita River (Red River basin) in Arkansas. On the White River in Arkansas these stations are known by the following names: Beaver, Lead Hill, Henderson, Cotter, Gilbert, Walls Ferry and Pangburn. On the White River basin in Missouri they are known as Branson, Galena, Tecumseh, Leeper, Eminence (Current River). Van Buren, Doniphan, Eminence (Jacks Fork), Chicopee, Bardley and Greer. The U. S. Geological Survey gaging stations on the Ouachita River in Arkansas are located near Hot Springs, Malvern and Arkadelphia. The University of Arkansas maintained seven stations in the White River basin from July, 1909, to September, 1910. These were located at Beaver, Branson, Lead Hill, Cotter, Gilbert, Henderson and Pangburn. The water flow data now available on Arkansas streams is not sufficient for a definite knowledge of the power possibilities of the main streams of northern Arkansas. No gaging stations are now maintained by the Arkansas Geological Survey, on account of lack of funds for this purpose.

Mineral Distribution, Value and Production MINERAL DISTRIBUTION The distribution of the various minerals of Arkansas is directly dependent on the geologic formations which are found in the different portions of the State. The Paleozoic, Coastal Plain and Igneous areas of the State contain mineral values that are characteristic of them in central United States. In the Ozark region are found the metallic ores of lead and zinc, manganese, copper, and phosphates, sandstone, marble, limestone, and dolomite. In the shales and sandstones of the Arkansas Valley are found coal, natural gas, commercial clays, and a relatively small amount of the metallic ores of zinc, lead, copper and silver. In the Ouachita Mountain area are found slate, novaculite, sandstone and the metallic ores of manganese, copper, silver, lead, zinc and iron. In the Athens Plateau are found small amounts of metallic minerals. Antimony is found in this section. The Mesozoic and Cenozoic rocks contain characteristic Coastal Plain minerals, such as oil and gas, asphalt, clay, chalk, marl, gypsum, greensand, sand, gravel, etc. The areas of the intrusive igneous rocks of Arkansas are comparatively small and occur in Saline, Pulaski, Pike, Garland, Hot Spring, Scott, Logan and Conway Counties. The igneous rocks in Saline and Pulaski Counties, like at least some of those in Garland and Hot Spring Counties, were perhaps intruded late in the Paleozoic times. Those in Pike County were intruded late in the lower Cretaceous epoch or early in the Upper Cretaceous epoch. The characteristic minerals found in the igneous areas of Arkansas are bauxite, diamonds, granite and small quantities of rare minerals. VALUE OF ARKANSAS' MINERAL PRODUCTION The total value of the minerals produced in Arkansas in 1924 is estimated at $64,774,185.60. This amount represents 1.2 per cent of the total value of the mineral products of the United States for 1924, which amounted to $5,318,000,000. The value of the fuel minerals, oil, coal and natural gas predominated in Arkansas by a very large margin in 1924 and made up about 94 per cent of the total value. The term "natural resources" usually includes agricultural products, timber, minerals, and water power. The total value of these products in Arkansas in 1924 is estimated at $387,826,294.00. Of this sum, the agricultural resources were valued at $238,735,800.00, the timber at approximately $84,088,309.00, and the kilowatt hours generated by water power at $210,000.00. The value of the minerals produced is nearly 17 per cent of the total value of these natural products. |
