It is a mixture of the two. For example: For Bull Shoals Lake, the 425 waypoints are all natural brush pile sites. Yes some of them are in bad shape and will be refreshed in the upcoming years. Whereas on Norfork Lake, the 16 of the 185 sites are artificial structure sites. All 169 natural brush pile site have been refreshed since Thanksgiving '18. We have been telling our GIS Division that each site needs to be mark to be able to tell whether it is natural or artificial and also when the site was established and/or refreshed.
Let me know if you have any issues with the downloads. We are working with the GIS division to improve this aspect.
