My experience mirrors Scott's above - I reseeded significant areas front and backside of dams on 3 ponds following construction and had zero topsoil and no irrigation option at the time. Erosion mat helped keep moisture on the seedlings and my wheat and fescue performed well. Unless you can water frequently, erosion mat is worth the cost to install.
