Report 67746: Couple describes strange loud animal vocalization near Beavers Bend State Park

My wife and I traveled from our home in the Dallas area for a 5 day trip to Hochatown, OK on Oct 26, 2020. It had rained all day and had gone to drizzle by the time we arrived at our cabin around 4:30 pm. We unlocked the cabin and went inside and looked around and then went out right before 5 to start unloading our SUV. My wife grabbed some items and headed inside. Right as she got inside I heard a siren go off in the area of Beavers Bend State Park to warn about water being released from the dam. Immediately I heard a load deep growl. After a few seconds the growl turned into a deep howl. This went on for about thirty seconds and was immediately followed by a loud high pitched scream. This was followed wooooing sounds that lasted about 2 minutes. My wife came out while this was going on. We didn't discuss it as I didn't want to tell her what all I had heard. We grabbed up some items and went into the cabin. Upon coming back outside the sound was gone. I heard the siren go off many more times while we were there but never heard any other sounds. I am an army veteran and also former scoutmaster and have spent a lot of time in the woods but have never heard a combination of sounds like this. I'm still not certain if this actually was one or a coincidence of several animal calls occurring one after the other. My wife thought the woooing sound was wind blowing in the forest when we discussed this after we got home. But at the time there was little to no wind blowing and we never heard that again although it blew quite a bit as it rained the majority of time we were there. I originally sent this sound combination to Cliff Barackman and mentioned the Ohio howl and after looking it up it did sound similar to that. At the time I hadn't really thought much about Bigfoot since back when I was in junior high in the 1970's but after this have become really interested in it after this.
