Predicting Harmful Algal Blooms.
11/20/2015 -- new report describes a study to predict cyanobacterial harmful algal blooms (cyanoHABs) at Ohio recreational lake sites. A cyanoHAB is a large growth of bacteria that produces toxins such as microcystin. CyanoHABs are a major water-quality issue for Lake Erie and inland lakes in Ohio. Staff collected data and made water quality and environmental measurements that were used to identify the potential for a system to quickly estimate microcystin levels and provide advisories to swimmers and boaters. This type of system has been used at Lake Erie beaches as part of the Ohio Nowcast for predicting E. coli concentrations, but has not been tested for cyanoHAB predictions. The results of this study showed that water-quality and environmental factors are promising for use in site-specific models for cyanoHAB predictions.
Striving To Prevent Reservoir Taste And Odor Issues.
9/28/2015 -- The City of Columbus and the USGS are collaborating on a synoptic survey of the lower portion of Hoover Reservoir to better understand factors that could affect taste and odor issues. The study includes measuring and mapping the bathymetry, water velocity, and selected water-quality characteristics during separate extended releases from two different release valves at the Reservoir to Big Walnut Creek. The results from the study will provide the City with information needed to make more informed decisions on reservoir releases.
Village Of La Rue Better Prepared For Floods.
9/28/2015 -- New digital flood-inundation maps for a 3-mile reach of the Scioto River through flood-prone La Rue, Ohio, are available at the USGS Flood Inundation Mapper and are described in a new report. The maps show estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the Scioto River at La Rue streamgage. The availability of these maps, along with information regarding current stage from the USGS streamgage and forecasted high-flow stages from the National Weather Service, will provide emergency management personnel and residents with information that is critical for flood response activities such as evacuations and road closures.
