7:30 Karen and Timmy met at Walmart to pick up supplies, then went to Stine’s to pick up plywood, lumber and other construction supplies.

Arriving at the headquarters around 9:30, we left the lumber on the Blue Goose under the boat shed and loaded the flat boat for a trip out to visit the Oysterbreak at Southwest Pass. Phase II of that project is complete, which means there are six segments of concrete rings placed in 3 different arrangements (single layer, double layer and double with gaps – see OysterBreak report). These linear concrete constructions are meant to attract reef-building oysters, create 3-D aquatic habitat and protect the shoreline from wave action.  Timmy had not been out that way for a while because of weather and other business (I’m sure it’s not the dredge), and on this day the LSU group was out for their monthly sampling trip and we wanted to see what they were finding. They reported all the seasonally expected small fish and nothing unusual. With all of the fresh water from the Mississippi River flood, there was no new oyster spat from the spring event, but the current salinity was running 10-13 ppm so there was hope for the fall spat.

We then took a run down the location canal at the west side of the SW Pass bay to make sure everything on this end of the property was good. There was a platform with a lot of bird activity so we stopped to take pictures of the nesting barn swallows.
Pop up storms threatened at SW Pass and then closed in around us on Vermilion Bay as we headed back the 25 miles in a flat boat to the headquarters.

We returned to camp for lunch and waited for the rain storms to pass. Late that afternoon, 10 sheets of plywood were unloaded from the Goose, carried up on the deck, and ripped into 2 ft wide by 8 ft long strips to use for containment. We also cut 2 sheets in half and framed up 4×4 markers that will be used for geo-referencing the photos we hope to acquire next month with LSU’s remote plane.
