#  ABSTRACT:  
#     The report authors maintained notes detailing the process that 
#     was used to do the analysis for this report. The pertinent 
#     notes were included in the appendix of the report. 
#     Some details that did not warrant publication reside 
#     in these notes. These notes are being archived in the 
#     event that they might be of use to future water-use 
#     efforts aimed at stream-valley aquifers.

OHIO DOCUMENTATION 
Last edited: August 22, 2005

           In Ohio water users that withdraw over 0.1 Mgal/d must register their withdrawals with the Ohio Department of Natural Resources, Division of Water. Through the Water Withdrawal Facility Registration Program, facilities provide information on withdrawal capacity, ground- or surface-water sources, location and type of water use, and location of discharge points.  Registered withdrawers file annual reports of their water use. In addition, Ohio State University has created Extension Fact Sheets on the water resources of every county in the State. In the fact sheet, there are sections on surface-water resources, ground-water resources, and water use. For public suppliers they provide information on the population served, water source (ground or surface water) estimated daily usage, and treatment plant capacity. 
      
      Estimates of alluvial withdrawals in Ohio for 2000 were 53 Mgal/d. The majority of the withdrawals were for public supply (39.4 Mgal/d); irrigation and self-supplied industrial withdrawals were much less (0.87 and 12.8 Mgal/d, respectively). Alluvial aquifer withdrawals accounted for only about 8 percent of total withdrawals from all aquifers in Ohio. In Ohio, much of the land lies north of the line of continental glaciation, and nearly 62 percent of total aquifer withdrawals from the three categories (public supply, irrigation, and self-supplied industrial) are derived from deposits identified as Glacial sand and gravel. Typically, withdrawals from sand and gravel deposits have not been differentiated as to whether the deposit is north or south of the line of continental glaciation. For this study, the disaggregation of withdrawals into specific stream-valley aquifers utilized pumpage classified as originating in Glacial sand and gravel in 2000.  Total withdrawals from the Other aquifer were 5.8 Mgal/d and originated from Cambrian-Ordovician and unknown aquifers.   

      Those counties whose total land area is south of the line of glaciation, and have Stream-valley Alluvium on figure 4 of the Ground Water Atlas are: Athens, Belmont, Carroll, Coshocton, Gallia, Jefferson, Lawrence, Meigs, Monroe, Morgan, Muskingum, Pike, Scioto, Tuscarawas, Vinton, and Washington.  Parts of Stark, Adams, Brown, Columbiana, Fairfield, Hocking, Holmes, Licking, and Ross counties are both south and   north of the line of continental glaciation and contain Stream-Valley Alluvium on figure 4 of the Ground Water Atlas.  Site-specific data provided the necessary information to facilitate the utilization of pumpage from all the counties listed above. 
      
      The Ohio Department of Natural Resources, Division of Water, has produced statewide GIS coverages for the unconsolidated aquifers of Ohio. These maps depict the approximate yield, in gallons per minute of the aquifers and include the additional attributes of drift thickness, hydrogeologic settings, local names, and lithology. Buried valley deposits are differentiated from alluvial deposits in these coverages. The alluvial deposits generally coincide with the Stream-valley Alluvium extent show on figure 4 of the Ground Water Atlas. This coverage was used to select wells within an SVA. In addition, county coverages of flood prone areas were used as a quality assurance check to insure that the alluvium is associated with an existing river and not an historic river valley. 
      
      
      
      
Note: 
      The DNR classifies Alluvial as Areas containing modern streams not associated with major buried valley systems. Includes primarily fines, water obtained from interbedded lenses or layers of sand and gravel. DNR provided a data set with Well Identifier, pumpage, aquifer code, county, category, 8-digit HUC and latitude and longitude.  In a document titled: State Aquifer Map Unconsolidated Aquifers Legend For Local Settings the rivers systems with productive alluvial deposits were discussed:  

Tuscarawas  Major tributary of the Muskingum River which drains a large area of eastern Ohio extending from Akron to Coshocton.

Muskingum  Large tributary of the Ohio River which extends from the city of Coshocton to Marietta. 

Walhonding  Tributary of the Muskingum River in western Coshocton County extending eastward from the confluence of the Kokosing and Mohican Rivers.

Scioto  Major tributary of the Ohio River draining much of central Ohio.

Hocking  A major tributary of the Ohio River in southeast Ohio. 

Sandy Creek  Tributary of the Tuscarawas River in Stark, Carroll, and northern Tuscarawas Counties.

Killbuck  A large tributary with headwaters in southern Medina County and that empties into the Walhonding River in Coshocton County.

Short Creek  Small tributary of the Ohio River in southern Jefferson County.
