- Strong wind events in the summer can cause upwelling, which brings this cold, hypoxic bottom water up to the surface close to shore. This can cause a sudden degradation to the water quality at nearshore drinking water intakes.

Oct 23, 2020 · The Experimental Lake Erie Hypoxia forecast is updated daily, and uses a hydrodynamic model and weather forecast data to predict the location and movement of hypoxic bottom water up to five days in advance. Hypoxia is a condition of low dissolved oxygen ( 2 mg/L) that can be harmful to aquatic life. Hypoxic upwelling events along the coast can ...

Jul 16, 2024 · The deep water often becomes hypoxic (low in dissolved oxygen) and has a low pH and elevated levels of iron and manganese. Strong wind events can cause upwelling, bringing this cold, hypoxic bottom water to the surface near the lakeshore.
3 days ago · This forecast uses a model of hypoxia and circulation in Lake Erie to alert decision makers of when upwelling may bring hypoxic water to the shore. The hypoxia forecast was developed by NOAA’s Great Lakes Environmental Research Laboratory, and is now being maintained by NCCOS.
Jul 9, 2024 · NOAA GLERL produced the Lake Erie hypoxia forecast each summer through 2023, prior to transitioning it to NCCOS for sustained operations. The model is integrated into the Lake Erie Forecast System, further enhancing the region's capability to manage water quality.
Oct 28, 2024 · Hypoxia is bad news for lake whitefish that prefer the cold bottom water of Lake Erie. But, while the cyanobacteria in algal blooms thrive in fertile, nutrient-rich waters, so too do the plankton that feed the lake's larger fish. And not all of those fish live at depths where hypoxia is a problem.
Oct 28, 2024 · The dashed line shows where bottom waters in Lake Erie are experiencing low oxygen, or hypoxia, created by nutrients that enter from agriculture. New research is showing that ecosystem management decisions focused only on minimizing hypoxic regions, often called “dead zones,” won’t necessarily benefit all fish.
Duration of hypoxic conditions. Large hypoxic water masses in the central basin of Lake Erie can persist for months, whereas discrete episodic hypoxia events have shorter timescales (Ruberg et al. 2007; Perello et al. 2017; Jabbari et al. 2019).
