Sleaford Mere Convervation Park Powertrail - you are looking for a rectangular container
The Sleaford Mere Conservation Park preserves a picturesque saline lake, which provides feeding habitat for a number of waterbird species, including chestnut teal which are known to breed in the park. Marine fish, including a large, land-locked population of skates are found in the Lake. We have also seen the odd skippy and emu when travelling through.
The Mere (as it's known locally) shares a boundary with the Lincoln National Park and there are several walks that will take you through both areas.
Happy Caching and safe travels!
