Some cleanup efforts seemed to withstand the repeated downpours, but others faltered. Farmers struggled to plant pollution-absorbing cover crops, for instance.

It will be months before anyone can fully gauge the impact of higher-than-normal river flows that began flooding the Chesapeake in May and persisted through the rest of the year.
