As propably only very few people know, a new museum opened in Deggendorf last year. In the Schiffmeisterhaus, the Wasserwirtschaftsamt (Bavarian State office for Water Economy, Dept. Deggendorf) opened a small but quite nice water museum. The current exhibition is about drinking water: where to find water, how to get to it, how to protect it. Sounds pretty dull but it's fun even for kids (many things to touch, and many buttons to press).
Bring a snack - the museum has a room with chairs and tables where you can have Brotzeit. There's also a coin-operated softdrink machine.

Info for disabled people:
The Museum is not suited for walking impaired people as there is only a steep staircase but no elevator. However, if you bring someone strong, we can carry you upstairs. Within the 3 stories there are no barriers for wheelchairs. On the ground floor is a toiled especially designed for people with wheelchairs.
If you walk with crutches, there are many chairs so that you can take a rest.

Widely suited for the blind. Many exhibits may be touched. No descriptions in Braille, though.

Opening hours: Tuesday through Sunday, 10 am - 4 pm. Free parking space for cars, motorbikes and bicycles directly in front of the museum.

If you'd like a guided tour in English, I'll be on duty there on June 7th (Sunday), 11th (Thursday, public holiday) and 28th (Sunday).
Or send me a PM and we'll arrange something

How to get there:

From the Autobahn: Take the exit to Deggendorf center. Turn right and go stright into Deggendorf for about 1.5 km until you see a baroque church to your left and a bridge to the right. Keep going straight ahead over this crossing and after it turn right into a small side road (There's a road sign saying Schiffmeisterhaus), Immediately turn left. After about 100 m the Schiffmeisterhaus is the old pale orange building on your right.

From the train station: exit Deggendorf station and take Bahnhofstraße straight ahead till the Marketplace (Luitpoldplatz). Turn right and proceed always straight ahead. After you went through a small tunnel (a former town gate) you'll see the afore mentioned Baroque church to your left. Cross the street, turn left and after about 50 m there's the little side street with the sign pointing to the Schiffmeisterhaus. It's a good half hour walk or 10 minutes by bicycle.
