Marshall Swamp
Marjorie Harris Carr Cross Florida Greenway
Imagine This Spot Underwater
If the Cross Florida Barge Canal had been built in the 1960s as planned, Marshall Swamp would be 13 feet underwater. The swamp sat in the path of the Dosh Reservoir. Plans called for flooding 20 miles of the Ocklawaha River and two miles of the Silver River so barges could cross the state's interior.
The natural beauty of these rivers had inspired awe and drawn tourists for decades. The threat of destruction provoked a surge of grassroots opposition. A coalition of scientists and citizens rallied behind the slogan "Save the Ocklawaha" and turned public and political opinion against the incomplete canal project.
A New Use for Canal Buildings
Although the reservoir was never built, other canal remnants still stand. The nearby Marjorie Harris Carr Cross Florida Greenway Field Office was originally built as a headquarters for canal management. Now, Florida Park Service staff plan environmental restoration projects and greenway maintenance there. You can explore the greenway to discover what the canal left behind.

1. Marjorie Harris Carr Cross Florida Greenway. One of the nation's largest incomplete public works projects has been transformed into the diverse Cross Florida Greenway, spanning Central Florida from the Gulf of Mexico to the St. Johns River.

2. Marshall Swamp Wildlife Management Area. The site features an impoundment that was created on the area in
the 1950s, when dikes and water control structures were installed on the Dead River, a tributary of the Oklawaha. The impoundment later became part of the Cross Florida Barge Canal project, which was decommissioned in 1971. In 1993, the impoundment and surrounding swamp were incorporated into the newly established Cross Florida Greenway. (Submitted on March 7, 2021, by Cosmos Mariner of Cape Canaveral, Florida.)
