Pass A Loutre
September 23, 2012 at 12:45pm
I have the Head Quarters complex located on a 1000 foot by 300 foot strip of land that is between Dennis and Johnsons Passes. It is at or about 29°07.0734 ~ N. Latitude ~ 89° 12.4584 ~ W. Longitude. One of the camping sites is the Loomis Pass #2 site is at or about 29° 7.3806~ N. Latitude ~ 89° 10.7220~ W. Longitude.
The Official LDWF web site at http://www.wlf.louisiana.gov/wma lists the Pass A Loutre WMA as having 5 designated tent-camping areas on the area and 3 areas which have been designated to allow the mooring of recreational houseboats. Prior to mooring; however, houseboats must receive a permit from the Department. More information can be obtained by calling 337-373-0032.
I have located some of the sites from the rough map that is included on their web site, but to get some of the others, I will need to contact the LDWF during their hours of operation.
I am working on the others locations and will amend this posting when I can get the info from LDWF.
Unless otherwise specified, all positions are stated as Degrees, minutes and thousandths of minutes (DDD,MM.mmm) and were determined using WGS 84 Datum. All bearings and courses are stated in Magnetic degrees.
On October 1, 2012 I received the following information from the Louisiana Wildlife and Fisheries:
All coordinates are in decimal degrees and datum NAD83
Headquarters N29.11789 W89.20764
South Pass Campground N29.10537 W89.23427
Cadro Pass Campground N29.09091 W89.21090
Loomis #1 Campground N29.12818 W89.19299
Loomis #2 Campground N29.12301 W89.17870
Southeast Pass Campground N29.13903 W89.14870
My calculations indicate that the positions converted to WGS 84 Datum and Degrees, Minutes and decimal minutes are:
Headquarters N29°07.0734 ~ W89°12.4584
South Pass Campground N29° 06.3204 ~ W89° 14.0562
Cadro Pass Campground N29°05.4546 ~ W89° 12.6540
Loomis #1 Campground N29°07.6908 ~ W89° 11.5794
Loomis #2 Campground N29° 07.3806 ~ W89° 10.7220
Southeast Pass Campground N29° 08.3418 ~ W89° 08.9220
Thank you for your patience.

I double checked all of the positions and I believe that my stated positions are correct.
The LDWF positions are stated in DECIMAL DEGREES (DDD.ddddd) and were made using NAD 83 Datum.
In converting these positions to a more familiar format of Degrees, Minutes and thousandths of a minute (DDD, MM.mmm) and using WGS 84 Datum I believe that they are as stated.
May I ask how you plotted the positions, on what map or chart and what datum did you use?
I use professional programs that includes Marine Charts, Topographical Maps in 1:100,000 and 1:24000 scale and ORTHO (corrected for the proper datum) high altitude aerial photographs.
I am going to try and attachι a photo of the campsite that was obtained using the ortho aerial photographs. The map photo created (taken) on May 10, 2010, shows that the site was recorded at a position on the left bank of Cardo Pass just in from the water on or by a high spot that appears to be a levee that helps impound two large fresh water ponds.
Both the LDWF and by plots coincide for the camp sites and the Head Quarters site.

I used WWW.itouchmap.com/latlong.html. You can plot using the points the LDWF provided and the points you provided at the same time.
i CAN PLOT IN OVER SEVEN DIFFERENT POSITION FORMATS, SWITCHING BETWEEN THE DIFFERENT FORMATS AS NEEDED.
I CAN PLOT IN THE DWLF FROMAT AND INSTANTLY CONVERT IT TO THE DECIMAL MINUTES.
CALL ME AT 985-847-0536
My PC died so I didn't have a chance to call. However, I believe the site I was using to plot the points was in a different format. I was using your points (HQ N29 degrees.07.0734 W89 degrees12.4584) when the site required that this be 29 degrees 7' 4.4034 and 89 degrees 12' 27.5034. Thanks for all the help. I'm new to this GPS stuff. Just trying to have my plans in order for a hog hunting trip in March. I'm a native of Louisiana, but a non-resident that live in Indiana. Thanks so much for your time!!!!!

I did a comparison to what the LDWF provided and your conversion coords and the points appear to be off by a good amount. Do you know why that would be? I'm trying to attach a picture for you to see. The middle and right blue points are for Cadro Pass Campground. The middle one is the LDWF points and the one to the right is yours (looks like that point might be in the water).
