OLINVILLE - Trash is piling up along the banks of the Bronx River, and experts are heaping the blame on fallen trees.

Residents have begun calling Shoelace Park a garbage dump and an eyesore around where a downed tree has turned into a sort of dam and started trapping floating garbage.

The Bronx River Alliance says it surveys the river and its surrounding area every week, but parkgoers say they want the cleanup to happen right away.

The city's Parks Department says it has a project underway to remove the tree and the trash it's collected, but a spokesman says the way the tree is positioned in the water makes the job difficult.
