Welcome to Onalaska, Texas. We are a small community with a BIG heart. Onalaska is unique in that the only way to get to our city is by crossing a bridge. Our population is 1,500 (city limits), but if you include most of the areas that the school district serves, our population is 4,500 . Our Elementary School serves approximately 550 students and our Jr-Sr High School serves approximately 350 students. A great site to find out more about Onalaska is The City of Onalaska's web page. You'll find that it's a fun place to visit, but it's a GREAT place to live!
