I live along the arsenal And ditto area. An arsenal bomb safety instructor told us 40 were released for beaver control on the Arsenal. They started reproducing. Sent a team to catch them to remove them and they only caught 16 and quit. I have spent a lot of time on the river from the arsenal to g ville dam. I have only seen 2 since 1995. These 2 were together. About 4ft long. In a swamp area on the east side if arsenal about 100 yards off the tenn river bank. Just down stream from ditto landing. Back in 2003 a friend showed a pic he took of an 8fter on a log in the flint river not far from the tenn river.
