Remodeling for the purpose of increasing the storage of the reservoir involves raising of the reservoir level above the normal operating level and this would result in additional submergence of land in the upstream. In the case of ungated spillways, the normal operating level is at the crest level and there always is a temporary submergence caused by the overflow depth during the passage of floods. Thus, the full reservoir level (FRL) can be raised up to the maximum depth of overflow corresponding to the allowable limit of the upstream submergence. However, with the gated spillways, the FRL is required to be raised, which brings additional area under the submergence, beyond that corresponding to the original FRL. Thus, the remodeling is to be accomplished under the above mentioned pre-requisites.
