AB: PURINSTALLATION OF LAND-TREATMENT MEASURES WITHIN THE 44,250-ACRE HACKLEBARNEY WATERSHED IN MONTGOMERY AND ADAMS COUNTIES, IOWA IS PROPOSED. A COMPLETE SYSTEM OF LAND-TREATMENT MEASURES WOULD BE INSTALLED TO PROTECT THE WATERSHED FROM EXCESSIVE EROSION. THE SYSTEM WOULD INCLUDE 225 MILES OF WATER AND SEDIMENT CONTROL BASINS, 146 GRADE STABILIZATION STRUCTURES, 100 ACRES OF GRASSED WATERWAYS OR OUTLETS, 5,805 ACRES OF CONSERVATION TILLAGE SYSTEMS, WILDLIFE HABITAT MANAGEMENT ON 300 ACRES OF UPLAND, CRITICAL AREA PLANTING ON 200 ACRES, AND 10 MILES OF DIVERSIONS. THE LAND-TREATMENT MEASURES WOULD BE INSTALLED BY INDIVIDUAL LAND USERS DURING A 15-YEAR PERIOD. ESTIMATED COST OF IMPLEMENTING PROJECT MEASURES IS $4.8 MILLION, AND THE BENEFIT-COST RATIO IS ESTIMATED AT 1.2. POSTHE PROGRAM WOULD COMPLETE PROPOSED LAND TREATMENT 151 YEARS EARLIER THAN CURRENTLY EXPECTED. APPROXIMATELY 850 ACRES OF PRIME FARMLAND WOULD BE MAINTAINED BY THE LAND-TREATMENT MEASURES. THE LAND-TREATMENT MEASURES WOULD CONTROL 100 PERCENT OF THE EXCESSIVE EROSION AND RILL EROSION AND 78 PERCENT OF THE GULLY EROSION WITHIN THE WATERSHED BY THE END OF THE INSTALLATION PERIOD. GRASSED WATERWAYS WOULD PROVIDE WILDLIFE HABITAT. APPROXIMATELY 200 ACRES OF HIGHLY ERODED OR ERODIBLE AREAS WOULD BE REVEGETATED AND MAINTAINED IN PERMANENT COVER. PHOSPHORUS AND NITROGEN LEVELS IN WATERSHED WATER WOULD BE REDUCED SIGNIFICANTLY. GRADE STABILIZATION STRUCTURES WOULD CREATE 388 ACRES OF POND HABITAT FOR MIGRATORY WATERFOWL AND FISH. SEDIMENT DEPOSITION TO VIKING LAKE WOULD DECLINE BY 3,100 TONS PER YEAR, IMPROVING FISH HABITAT. THE 272 FARMS PARTIALLY OR ENTIRELY LOCATED WITHIN THE WATERSHED WOULD BENEFIT FROM INCREASED PRODUCTIVITY. NEGIMPOUNDMENTS CREATED BY GRADE STABILIZATION STRUCTURES WOULD INUNDATE 115 ACRES OF FARMLAND, AND OTHER LAND-TREATMENT MEASURES WOULD RESULT IN THE CONVERSION OF 338 ACRES OF FARMLAND TO GRASSLAND. APPROXIMATELY 35 MILES OF STREAM CHANNEL WOULD BE FLOODED BY POOLS ASSOCIATED WITH GRADE STABILIZATION STRUCTURES.
