Rivers and Streams
Two waterways form major features within the park: Travertine Creek and Rock Creek.
Numerous other streams run into the Lake of the Arbuckles.
A unique feature of this stream is its ability to form an unusual rock called travertine, from which the stream gets its name. The water of the stream is so highly charged with dissolved calcium carbonate that upon exposure to air much of the mineral will precipitate to form a buff-colored deposit. Large accumulations form a porous travertine rock. Plant leaves and branches along the stream may be covered with a film of travertine dust from wind-blown spray. Small travertine terraces may be observed along the length of the creek.
This is the largest of the streams entering the park, with a total drainage area of 170 square miles. Because of its size and permanence, this stream provides excellent habitat for fish and other aquatic species.
