Water Quality In Grand Lake St. Marys.
2/3/2015 -- Cyanobacterial harmful algal blooms (cyanoHABs) can produce toxins harmful to humans and deadly to fish and pets. CyanoHABs have become common in Ohio’s Grand Lake St. Marys, the largest manmade lake in Ohio and also a state park. A recent USGS report describes findings from 11 sets of water-quality samples at six lake sites during 2011-2012. Samples were analyzed for concentrations of a suite of chemical constituents, chlorophyll, and microcystin and to determine plankton community structure and abundance. Molecular methods showed Planktothrix to be the dominant cyanobacterial genus. Molecular method results were also correlated to other water-quality constituents. Other cyanoHAB research underway at the USGS Ohio Water Science Center includes relating toxins in the sediment with bloom occurrence and predicting cyanoHABs at inland lakes and along Lake Erie Beaches. More information on cyanobacterial blooms in Ohio as well as USGS cyanotoxin research can be found on the web.
National Water Use At Lowest Level Since Before 1970.
11/20/2014 -- Water use across the country reached its lowest recorded level in nearly 45 years. According to the newly released report Estimated Use of Water in the United States in 2010 and as described on the USGS Water Use webpage, about 355 billion gallons of water per day (Bgal/d) were withdrawn for use in the United States during 2010. Ohio ranked 12th in State total withdrawals, with 68 percent of withdrawals in Ohio used for thermoelectric power. The USGS compiles and disseminates the Nation's water-use data, including a report every 5 years. (news release)
Paddlers And Anglers Rely On USGS Data.
10/14/2014 -- Data from streamgages are vital for managing catastrophes such as floods—but month after month, the top consumers of USGS streamgage data in Ohio are paddlers and anglers. Gage data inform anglers whether the water is a suitable temperature and flow for fishing. Before paddlers head out, they can check whether there is enough or too much water to safely and enjoyably canoe or kayak. Use USGS WaterWatch to view real-time streamflow data, USGS WaterNow to query a USGS streamgage via email or text messaging, and USGS WaterAlert to be alerted when certain parameters such as gage height exceed user-defined thresholds. There are also many third-party smart phone apps and websites that access USGS real-time water data. In Ohio, the more popular gages for recreational purposes (fishing and/or paddling) include the Grand River near Painesville, Rocky River near Berea, Chagrin River at Willoughby, Mad River near Urbana, and the Little Miami River at Milford.
