The means of the two replicate sediment grabs taken from each site were used to estimate total organism density among bayous and total organism abundance per phylum among bayous.
Due to the missing samples from Bayou Casotte, it is not possible to determine a fair comparison between the three bayous, however, throughout the sampling period; Bayou Cumbest contained higher benthic invertebrate counts than Bayou Heron throughout the study period (Fig.
The bayou was once a main channel of the Mississippi River (its name means "fork" in French), but it was dammed off in 1904, after area residents complained of the great increase in annual flooding; the entire river to the north had been enclosed with levees to prevent upstream flooding and almost 2,300 miles of riverwater were coursing into the bayou.
Then two devastating hurricanes--Gustav and Ike--slammed directly into the bayou in the summer of 2008, doing even more damage to the area than the two "girls gone wild" (according to a T-shirt sold in New Orleans' French Quarter), Katrina and Rita, did in 2005.
Considerable data have been collected from Houston bayous over the past almost 20 years by the city of Houston, the Texas Natural Resource Conservation Commission (the state environmental agency), United States Geological Survey, and other agencies.
The monitoring data indicate that average FC levels in the bayous increase slightly as water flows downstream, suggesting that FC input comes from tributaries, point sources, and/or non-point sources along the bayous.
For Tim Gallagher, it was reading a posting on a canoe club listserv about a strange woodpecker a kayaker named Gene Sparling had seen on a float trip down a remote bayou
in eastern Arkansas.
Houston's natural bayous
provide a range of recreational opportunities as well as scenic beauty," Mathis explained.
Black is now open from Mile Marker 84 eastbound, and Bayou
Boeuf is open from Mile Marker 86 westbound, so only a two mile stretch of the Intracoastal remains closed as a safety precaution.
