Clean Lakes Alliance Executive Director James Tye said Thursday that years of monitoring has recorded a 36% reduction in phosphorus concentration in local lakes.
Tye, speaking at Downtown Madison Inc.’s “What’s Up Downtown” series, brought business and community leaders up to date on the Alliance’s “Renew the Blue” community action plan to clean up the Yahara watershed.
The plan has played an important role in the reduction of phosphorus in local lakes but Tye said increased rainfall and runoff have undermined that progress.
The Yahara watershed includes five major lakes that contribute more than $220 million annually to the regional economy.
