Bay Vuisiit, which is practit-ally a long arm of Sister Lake, 

 extends from the west side of that lake, above the entrance of 

 Grand Bayou dii Large, nearly to Little Indian Bay. It is con- 

 nected with King Lake by a narrow cut off, and some small 

 l>ayous going off from its south side connect with Bay Jack 

 Stout. 



The depth of water iu this bay is very uniform, being 

 about three feet over the whole bay. The bottom is composed of 

 soft mud in the e'ast arm, while in the west arm the bottom is 

 generally harder and there are several well-defined dead reefs. 

 In 1898 Dr. J^Ioore reported that some especially good oysters 

 were taken from this bay; but at the present time .there are no 

 living oysters to be found on any of the reefs. There are a 

 few small 'reefs of poor oysters in the bayous going off from 

 the south side of the bay, but none of these reefs are large 

 enough to be of any commercial importance. The average 

 .•;alinity of the water was 1.0118, and there were no fluctuations 

 !)f any importance as a result of the freshets of 1907. The food 

 supply, both in kind and abundance, was very similar to that 

 found in King Lake and in Sister Lake, through both of which 

 the water flows to reach this bay. 



Bayou Grand CaiUuii empties into the Gulf about one-fourth 

 of a mile east of the mouth of Grand Bayou du Large. It runs 

 nearly northeast for about two miles, then bends to the east- 

 ward and runs nearly east along the south side of Sister Lake 

 for some five miles, where it bends to the north again and runs 

 far back into the high land. Near its mouth it is about one- 

 quarter of a mile wide, while the average width is about 200 

 yards. The depth of water in the lower part of the bayou varies 

 from twelve to thirty-five feet in the channel, and there are 

 some large mud flats on either side. There are reefs of oysters 

 beginning at a point about three-quarters of a mile from the 

 mouth of the bayou and occuring at intervals as far up as the 

 salinity of the water is sufficiently high to maintain the life of 

 . oysters. The important reefs are all, however, below the point 

 where Mile Pass connects the northeast corner of Sister Lake 

 wnth this bayou. Some of the reefs in the lower part of th? 

 bayou extend entirely across the ehannol. but most of them 

 are in the shallow water on the sides. Some five or six miles
