Ulla, as great the predator solution might sound, I live on several acres where gophers rule. There are lots of predators, hawks, owls, bobcats, foxes, etc., that spend their days/nights looking for food, and I have yet to see fewer gophers, ever, in 30+ years.
There are owl/hawk poles you can install that need to be 10+ feet above the ground, should have a cross-piece at the top so they can sit and watch. Once they catch a gopher or mouse, they want to fly to a protected place to eat it, like big tree branches, so that combo will do something, but not nearly enough. I have noticed that they get the rabbits that get past the fence on occasion, but the rabbits have fewer places to hide in my garden than in their brush-covered habitats.
Don't know how big your garden is, or how much the soil freezes in the winter (mine doesn't,) I have started lines of asparagus/narcissis/dock weed going down the fenceline, just trying to wall them out. I started at the most active places where they came under the fence, then spread along the fenceline from there.
Asparagus has a huge root system they avoid, can live for 20+ years, it a tough plant. Clip off the spears as they appear so it will grow and produce more, making more roots. If it is left on the plant, it turns into a fern right away and doesn't get as big as it could.
If you notice a native weed in your area that the gophers leave alone, doesn't compete with your plants or isn't too invasive, it could help be a part of that underground barrier. Narcissis bulbs multiply faster than daffodils, those can be tucked into that line.
Elephant garlic is fabulous, and is a great companion plant to roses and a lot of other plants.
Mediterranean climate, hugel trenches, fabulous clay soil high in nutrients, self-watering containers with hugel layers, keyhole composting with low hugel raised beds, thick Back to Eden Wood chips mulch (distinguished from Bark chips), using as many native plants as possible....all drought tolerant.
