Texas Artesian Water.
State Geologist Dumble has made a preliminary report on artesian water of south Texas. The following is a synopsis: That country he separates into two physical divisions: 1. The Nuecesbasin. 2. The coastal slope. Many of the sand beds of the Nueces basin, he reports, are water-bearing, but there are only two principal belts which give promise of furnishing a supply for flowing wells for general use. The amount of mineral water contained in some of the others would likely tender them unfit for domestic use even if the conditions were favorable for securing flowing wells from them, The water from these two belts will also contain some mineral matter, but much of it will be good water. The first of these belts, consisting of interbedded sands and sandy clays, has a breadth of some eight miles and a thickness of 300 to 400 feet. The general elevavation of the surface above the sea is 600 to 700 feet east of the Nueces river, and below the mouth of the Frio these sands will furnish flowing wells in the low lands of Live Oak and Bee counties. The depth of these wells will increase to the southeast. At Beeville a flow may be obtained at 1200 to 1600 feet, but the character of the flow will depend upon the sand in which the water is found. West of the Nueces there is a probability of obtaining flowing wells in McMullen, I.a Salle and possibly the northeastern portion of Encinal counties, but there is little chance for them outside ol this, the depth probably not exceeding 1000 feet.
The sands on the coastal basin will give flowing water in Nueces county and possibly in the northern portions of Hidalgo and Cameron, at points where the elevation does not exceed seventy-five to 100 feet above the sea level. It is this same series of beds which affords the abundant supply of water in the coast country east of the San Antonio river, and it is probable that the belt extends along the gulf margin from the Sabine to the Rio Grande. I believe that flowing wells are certain at any point on the coast where the elevation does not exceed 100 feet.
The detailed report is now in preparation, but as it may be some time before it is published, Mr. Dumble will take pleasure in corresponding with those interested in regard to the probability of obtaining water within the area under consideration.
