Abstract

The visual inspection, operational history, and hydrologic/hydraulic analysis indicate the facility is in good condition. It is recommended that the owner: (a) Immediately fill and seal all cracks within the interior of the outlet conduit. (b) Specifically address the seepage condition observed to the right of the spillway in all future inspections and note any turbidity or changes in the rate of flow. (c) Re-evaluate and revise the present standard flood emergency procedures in accordance with, but not limited to, the following items: (1) Include a definite procedure of notifying downstream residents of a possible emergency. (2) Provide for an alternate means of communication in the event telephone lines become inoperative. (3) Provide for around-the-clock surveillance of the facility during periods of unusually heavy precipitation. (d) Provide additional riprap protection along the right sidewall of the spillway approach channel.
