CAN HIGHWAY FILLS, CULVERTS AND BRIDGES BE MORE EFFECTIVELY USED AS WATER RETENTION STRUCTURES?

GROUND-WATER IS REPLENISHED ONLY THROUGH RETENTION AND ABSORPTION OF RAINFALL. ALL FEASIBLE PRACTICES THAT CATCH AND RETAIN RAINFALL WILL INCREASE ABSORPTION AND IMPROVE GROUND-WATER SUPPLIES. RAINFALL THAT ESCAPES AS SURFACE RUNOFF ADDS NOTHING TO THE USEFUL WATER SUPPLY AND USUALLY CREATES SERIOUS EROSION, COSTLY FLOOD DAMAGE, AND UNNECESSARY SILTATION OF RIVERS AND HARBORS. CONSERVATION FARMING METHODS, FARM PONDS, AND ALL OTHER PRACTICES THAT CATCH AND HOLD RAINFALL NEAR THE POINT WHERE IT FALLS, GREATLY REDUCE THE DAMAGES RESULTING FROM EXCESSIVE RUNOFF AND CONTRIBUTE TO THE PERMANENT UNDERGROUND WATER SUPPLY. MANY HIGHWAY FILLS COULD BE CONSTRCTED AS, OR CONVERTED INTO, IMPOUNDING STRUCTURES WITHOUT AFFECTING THEIR USEFULNESS FOR HIGHWAY PURPOSES. MANY HIGHWAY CULVERTS ON SMALL DRAINAGEWAYS COULD BE CONVERTED INTO DROP- INLET STRUCTURES AND PROVIDE A LARGE NUMBER OF SMALL WATER-STORAGE RESERVOIRS. ON MANY SMALL STREAMS, A COMBINATION OF EARTH FILL AND CONCRETE SPILLWAY MIGHT OFTEN TAKE THE PLACE OF CONVENTIONAL BRIDGE OR CULVERT DESIGN. LARGE IMPOUNDING AREAS MIGHT BE PURCHASED, OR CONTROL OTHERWISE ACQUIRED, BY THE STATE, AND PUBLIC FISHING AREAS PROVIDED IN COMMUNITIES WHERE THESE FACILITIES ARE NOT ADEQUATE. INCOME TO THE STATE FROM FISHING RIGHTS AND LICENSES WOULD BE INCREASED, AND NEEDED RECREATIONAL AREAS PROVIDED. ALL OF THE ABOVE BENEFITS ARE IN ADDITION TO THE PRIMARY PURPOSE OF THESE PONDS--THAT OF IMPROVING WATER RESOURCES AND INCREASING MUCH NEEDED GROUNDWATER RESERVES. /AUTHOR/
