County rangers were alerted using the County Sheriff dispatch (916-875-7275). A ranger quickly responded and we were able to locate the neighbor who reported the Sea lion sighting. Fortunately, the animal appeared healthy and was back in the river. Apparently an off leash dog encountered it while it was entering the river and was quickly chased away when the Sea lion charged back towards shore. Maybe it was protecting a favorite fishing or sunning spot? Several other people wandered by and were able to get good looks at an adult Sea lion calmly swimming just off shore. It looked healthy and well fed.
