Recently, a rare sight of a mom/calf pair of dolphins traveling the San Bernard River was seen. This was quite far inland for them because most dolphins reside primarily in saltwater environments.
Heidi Whitehead of the Texas Marine Mammal Stranding Network, asked on Facebook what was the level of salinity of the river. Denise Wolever, river resident, FOR Director and Texas Stream Team volunteer conducts monthly water testing of the river had the answer.
“These are the salinity levels taken in the past three months. As a comparison, I am also including the salinity levels from the same months in 2021.
05-17-2022: 26.9 ppth - 05-12-2021: 1.2 ppth
06-20-2022: 25.0 ppth - 06-08-2021: 1.2 ppth
07-24-2022: 28.7 ppth - 07-17-2021: 1.0 ppth
Our higher salinity levels are due in large part to the below average rainfall this year…. As seen in the post on Facebook, we have frequent sightings of dolphins along the river. In my area, we have a Dolphin sighting group and post sightings so that all can follow their path."
Heidi replied, “If dolphin sightings are posted on the FOR group page and I am able to have access/join, I am happy to pull the reports from directly from the page so as not to make extra work for others to report. The specific location, photo(s), and time of day are helpful for the sightings. It sounds like the dolphins are doing okay but we’d like to keep tabs on them. We’ve recently had some go up into the Brazos River and Oyster Creek, 20+ miles inland, and unfortunately had two die, so we’re just trying to keep track of them and their skin/body condition just in case there is any sign of an issue as salinity/prey availability changes…Thanks again for getting in touch."
