AB664,1,3 1An Act to renumber and amend 30.10 (2); to amend 30.01 (4m) and 30.10 (4)
2(c); and to create 30.10 (2) (a), 30.10 (2) (b), 30.10 (2) (c) and 30.10 (2m) of the
3statutes; relating to: navigability of certain bodies of water.
Analysis by the Legislative Reference Bureau
Under the state constitution, bodies of water in the state that are navigable in
fact are held in trust by the state for the benefit of the public, and no person may
infringe on the public's right to use any navigable water without the permission of
the state. Under current statutory law, the department of natural resources (DNR)
has the duty to safeguard this public right, and the placement of any type of structure
or obstruction in a body of water that can in fact be navigated is subject to regulation
by DNR.
Streams, sloughs, bayous and marsh outlets
In determining whether a stream is navigable in fact, courts have held that it
is navigable if it is possible to float a small craft, such as a canoe, on the stream at
some time during the year for recreational purposes. Current statutes do not specify
this test or another test to be used in determining whether a stream is navigable in
fact.
For streams, sloughs, bayous and marsh outlets, this bill establishes a test that
must be met for the body of water to be declared by DNR to be navigable in fact. The
requirements under the test include that the body of water be able to float a 16-foot
canoe with a 6-inch draft carrying a person who weighs not less than 120 pounds or
that the body of water be determined to be navigable by statistically calculating its

annual recurring water flow based on a 4-hour to 6-hour storm with a recurrence
interval of at least 2 years. The test also requires that the stream, slough, bayou or
outlet has an identifiable stream history and naturally occurring bed and bank and
that the stream, slough, bayou or outlet provides quality recreation for a period of
at least 24 consecutive hours at least once a year.
The bill also requires that if a stream, slough, bayou or marsh outlet is divided
by a structure that is used for pedestrian or vehicular traffic, each portion of the
divided body of water must meet this navigability test.
Farm drainage ditches
Under current law, a farm drainage ditch is not considered navigable unless it
is shown that it was a navigable stream before ditching. This bill requires that this
showing of navigability be documented on maps, in land surveys or by other
documentation.
Current law defines a "farm drainage ditch" to be an artificial channel that
drains waters from agricultural lands. This bill changes the definition so that the
channel need drain from agricultural lands only at the time it was created.
Therefore, a farm drainage ditch that is subsequently changed to another purpose
is still considered not navigable.
