Looking Back

Before the taming of the
upper Ocklawaha, the slug-
gish river ranged from 30 to
500 feet in width and had an
average depth of three feet.
To improve navigation, channel
obstructions were cleared by removing
snags, overhanging trees and floating
islands of vegetation. These floating
islands were formed when rising water
levels caused sawgrass and water lilies
on the bank to break off and drift into
the channel, hindering passage where
they caught in a river bend.
Local farming interests pressed for
draining the fertile lands adjacent to
the river and finally won congressional
support in 1917. As a result, federal
engineers constructed a lock and dam
at M ss Bluff and abandoned the river
chajp I from Starkes Ferry to Moss
B Uby diverting the flow into a canal.

Benefits and Costs

of Changes

The primary benefit from most of
these projects was flood control. In
addition, the water control structures
permitted engineers to stabilize lake
levels. That way, the lakes could be
operated within a narrow range to
store water in case of drought and
also allow year-round navigation. And
by draining the Ocklawaha's marshes,
more than 30,000 acres of productive
muck farm land was established in
Lake, Marion and Orange counties.
Unfortunately, these same factors
are key reasons why the water in the
Ocklawaha Chain of Lakes and river
has been polluted during the last 40
years. The dams ha kept water

Restoration Efforts


Because of these problems, the
restoration of the upper Ocklawaha
River basin is a priority for the
St. Johns River Water Management
District. The District's Surface Water
Improvement and Management
(SWIM) program has begun a healing
of the riter and its floodplain
The centerpiece ot the program has
beer the purchase of large tracts o:
the drained rrmars hes. which v 1ilI be

establish a functioning system by
diverting some of the flow from the
channelized Ocklawaha River back into

As a participant in restoring and protecting this vital river system, your active
support of this Surface Water Improvement and Management (SWIM) program is
key to its success. Funding is limited across the state. By working together, we
can improve water quality and restore the wetland habitat, recreational values
and beauty of the historic Ocklawaha River system.
For more information on the Upper Ocklawaha River Basin SWIM program, or
to arrange for informational displays, speakers or tours of the restoration sites,
