This is a well-done proposal with technically sound methods and well-qualified principal investigators, but the problem has already been addressed in Lake Pend Oreille. This proposal is likely five years too late. It is an interesting research project but geared to advancing knowledge of the dynamics of deepwater substrate, not to benefiting fish resources. IDFG proposal 199404700 shows how kokanee spawning gravel can be made available by managing lake level, which is being done, and makes it clear that there is no longer a problem for this proposal to address.
