HS student thinking about GIS

I'm graduating soon and I've been thinking about what I want to do. I'm thinking I'm probably shooting for an environmental science degree and I've been debating going into hydrology or GIS. I don't really know how the job market is for this, or the pay, or anything really. Any advice would be appreciated, weather it be about best paths to get into GIS degrees or reasons why I should/shouldn't choose this, anything helps. I do have some connections with my local watershed council, but I'm still worried about getting a job
