ANN ARBOR—If they successfully invade Lake Erie, Asian carp could eventually account for about a third of the total weight of fish in the lake and could cause declines in most fish species—including prized sport and commercial fish such as walleye, according to a new computer modeling study by scientists at the University of Michigan, NOAA's Great Environmental Lakes Research Laboratory, other U.S. and Canadian research institutions.

Scientists from NOAA, the U.S. Army Corps of Engineers and Environment Canada have issued a six-month forecast for water levels to be at or above average on Lake Superior, Michigan, Huron, and Erie into spring of 2016. Lake Ontario water levels are expected to remain close to monthly averages. However, the impacts of the anticipated strong El Niño and other atmospheric anomalies on the forecast are difficult to predict.

As part of efforts to enhance its Experimental Lake Erie Harmful Algal Bloom Bulletin, NOAA is offering the HAB Tracker, a new experimental forecasting tool that aims to aid local managers in decision-making on harmful algal blooms (HABs). The experimental tool is available online on NOAA’s Great Lakes Environmental Laboratory (GLERL) website, and incorporates real-time data with modelling to produce daily an updated 5-day forecast of potential bloom distribution and movement.

In the Great Lakes region, memories of the brutal winter of 2013-2014 are still fresh in residents’ minds. That winter brought very cold surface water temperatures and high ice cover well into the 2014 spring. Coupled with a record-setting water level surge of nearly three feet between January 2013 and December 2014, people who live along the shore of Lake Michigan have been wondering whether this is the “new normal” for the lake.
