Fishing Castle Loch: what the data says
184-acre lake near Dumfries and Galloway. The lake tops out around 11 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Castle Loch runs 184 acres with 2.6 miles of edge. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory.
