MT, the last inspection was last November, all was apparently well then. Like the report states, Ulley Resevoir is one of a similar design and when it constantly rained the slipway just simply couldn't cope with all the excess rain. The inevitable resulted in part of that dam giving way, similar to this one.
Trust all works out well for the residents and the dam doesn't give way. Don't think I could live at the base or near a dam tbh.
