The U.S. Geological Survey has issued its report of water availability in three reservoirs in east-central Ohio.
The report looks at Atwood, Leesville and Tappan lakes in the Muskingum Watershed Conservancy District.
The report by USGS staffer Gred Koltun was commissioned because drillers were seeking water from those lakes to frack Ohio's Utica shale.
The 33-page is a statistical analysis of water levels in the three reservoirs.
Koltun looked at three different pumping scenarios in doing his analysis.
The report offers no conclusions, just a statistical analysis, said USGS staffer David Straub.
That analysis indicates that water levels are the lowest from June to October and again in February when the lakes are refilling after having been lowered for the winter.
Water is most abundant in the spring and again in the late fall when the reservoirs are lowered for the winter.
The district is satisfied with the USGS findings and considers the report to be helpful data, said spokesman Darrin Lautenschleger.
The report increased the district's knowledge about water availability and confirmed that there are seasonal trends in water availability, he said.
The district has contracted with the USGS to conduct a similar analysis of its seven other reservoirs. That analysis is scheduled to be completed in 2014, he said.
