faltersainse [42]

Water drains into the sinkhole pollution due to factories

The lake was created as limestone gradually dissolved, causing the sediment layer above it to collapse and creating the lake basin. Low lake levels and slow draining can be caused by bottom leaks, sinkholes, and swallets, long-term dryness, and a lack of recent, strong rainfall events.

<h3>What causes lake Jackson to disappear ?</h3>

Before the lake dried up, those walking along the shore of the sinkhole at Lake Jackson on Thursday would have been in three to four feet of water.

  • Environmentalists refer to the process as a "dry down," and it occurs every ten or twenty years. The likelihood of causes includes dry weather, a lack of rain, and a decreased water table.

  • The lake will typically begin to fill again after the sinkhole plugs itself, sometimes taking years to do so pre sinkhole level
