We've made a New Wall Décor - Lake Tahoe. Multi-layer map with water depth in layers.

In this video I use some new techniques and materials. Maybe it will be useful for you, and I will be glad if you have experience and share it.
If you like the products and wish to purchase it, here is a link to our Etsy shop:
