The small karst feature (sinkhole) on the northeast side of Weimer Lake (in Wapehani Park) has greatly increased in size and depth over the last several months, and the lake is draining away! The water level has dropped by a few feet, and the lake surface has shrunk by half. The city already lost one reservoir this way in the 1940s (the one in Leonard Springs Park); would not it be a shame to lose another one? Is there a way to plug the hole (dumping a truckload of gravel and cement into it, perhaps?) before the entire lake flows aways? The picture shows the lake and the sinhole as of a week or so ago; since then, the water level dropped another foot or two, as the sinkhole's draining point is now much deeper than it was back then. And there seems to be more space for further drop...
