The Obama administration is preparing to release a 5-year blueprint for fighting invasive species and otherwise improving the Great Lakes environment.
Lisa Jackson, head of the Environmental Protection Agency, has scheduled a news conference for Sunday morning in Washington to announce the plan.
President Barack Obama has pledged to spend $5 billion over a decade on restoring the lakes by attacking problems such as toxic contamination and wildlife habitat loss.
Last year, Congress appropriated $475 million toward that goal. Obama has requested an additional $300 million in his 2011 budget.
Jackson will outline specific steps for spending the money. Agencies plan to use some of it to prevent Asian carp from reaching the lakes.
