The Adobe Dam project benefitted by an unusually wet winter which made it difficult to fully evaluate the success of some of the experimental modifications, especially the watering regime. Table 1 compares the relative success, energy costs and aesthetic appearances of the planned and experimental revegetation procedures used at Adobe Dam. Success of seeding was based on seeding survival of the seed species used in the seed mix. No location had a high seedling success rate. The topsoil and fill material were about equal while the rip-rap tended to attract annual weed species. Energy costs i.e., equipment use for different surface materials is highest for topsoil because it is an additional step over rip-rapping which is an additional step over smoothing the fill surface which is more costly than leaving the fill surfce roughened.
