The river opens into a broad basin and is lined by the parks of the Charles River Reservation. Lower pH readings are sometimes seen in fresher waters due to acid precipitation or even naturally-occurring organic acids, which can be found in bogs and some wetlands. For example, saltwater has a lower freezing point than freshwater, meaning that at 0 degrees C freshwater will freeze but saltwater will remain liquid. Lake Charles.
