AR Tessie on the Lake

Find Tahoe Tessie

Tahoe Tessie isn't real, but climate change is!

Find Tahoe Tessie is an Augmented Reality (AR) gaming app which places the mythical Tahoe Tessie in and around Lake Tahoe. Use your smart phone to capture (a photo) of Tahoe Tessie thriving in Lake Tahoe, share content on social media, and learn about the impacts of climate change on the lake, Tahoe Tessie, and other aquatic organisms. There are multiple Tessies to be found and viewing Tessie in augmented reality can be done anywhere but she looks best at the lake.

While using the app, players become scientists and throughout the game find scientific tools used for various lake experiments, explore Tahoe through local excursions, and apply scientific knowledge that will help find Tahoe Tessie. There are many scientific discoveries to be made throughout this app and while this fun is for the entire family, our learning objectives target students in the 3rd to 5th grade range. At the end of the game, players will have an improved comprehension and better understanding of climate change and its impacts to freshwater ecosystems

Download the Find Tahoe Tessie app currently on the Apple App Store and the Google Play Store for android devices links. 

About Tahoe Tessie

While Tahoe Tessie is not real, the characteristics of this mythical creature are based on real aquatic organisms from Lake Tahoe such as the native Lahontan Cutthroat Trout. Similar to other aquatic organisms that live in Lake Tahoe, Tahoe Tessie’s health depends on:

  • Water temperature - Aquatic organisms at Lake Tahoe depend on cold water and lake temperatures are warming due to climate change.
  • Dissolved oxygen - Cold water holds more dissolved oxygen which is essential for aquatic organisms like fish and zooplankton.
  • Lake clarity - This affects the depth at which algae (food for fish) grows and all sight-feeders need clean, clear water to see and hunt for food.
  • Algae - While algae make up the base of the food web and is crucial for the survival of other organisms, too much algae can make it harder sight-feeders to find their food and can create toxic environments such as Harmful Algal Blooms (HABs). Warming temperatures
