a. Reservoir enlargement applications should be submitted on Form S.W. 3 (the same form and procedure as used for original reservoir applications). The name of the reservoir should indicate the enlargement of the reservoir involved; for example: "The Enlargement of the Model Reservoir." Underneath the name of the reservoir, show the permit number of the original reservoir to be enlarged and any existing valid enlargements.
b. Previous instructions given for reservoir applications and original water right applications would apply, with the following exceptions: NOTE: The capacity table on the map should clearly show the capacity of the reservoir at the original high-water line elevation. It should also show the enlargement capacity between the high-water line of the original reservoir and the high-water line elevation of the reservoir enlargement. Be sure the capacity figures shown on the map agree with those shown on the application. (See sample map on page 65.)
