The data for the lakes consist of only data of dropping points of the
water.
Where is the lake itself?
The Kashmir stores the lake itself as a cache data. Consequently the larger the size of the cache the more lakes can be stored. It is even possible to display the lakes without cache. But it may take much time to display the map for the first view.
For setting up of the cache select [View] - [Memory Options]. It is recommended to setup the cache size larger.
