克罗蒂面板堆石坝是世界上首次在面板坝顶及下游坝面上布置开敞式溢洪道的工程。该溢洪道自１９９２ 年１ 月建成以来已泄洪多次， 其中有两次泄洪持续时间达１ 个月之久。虽然迄今为止泄洪流量较小（最大堰上水头仅 ０．７ ｍ ）， 但从现有观测成果判断， 大坝运行情况良好，推测今后出现最大洪峰（溢洪道的泄流量达２４５ ｍ ３／ｓ）时仍将正常运行 The Croti Panel Rockfill Dam is the first project in the world to deploy open spillways on the dam crest and downstream dam surfaces. Since the completion of the spillway in January 1992, the spillway has been discharged several times, of which two have been discharging for a duration of one month. Although the flood discharge has so far been limited (only 0.7 m on the largest weir), judging from the available observations, the dam is in good condition and the largest peak is expected in the future (spillway discharge of 245 m 3 / s) When it will still be normal operation
