The Trinity River system is a very vast area covering multiple waterways. With the Dallas-Fort Worth Metroplex straddling it northern area, it is the last place you would think that generates current reports. There are reports covering over 150 years, and that shows no signs of changing anytime in the future.
In the map below you will find an interactive map displaying many of those sightings in regard to the river system. Please take a little time and study the sightings and their locations. The locations are accurate to where they were reported, with the few exceptions noted in their descriptions.
