1 murder a year, 15 rapes a year, 20 robberies a year, 30 assaults a year.
Those numbers make Watertown a bit more unsafe than the average American city.
Non-violent crimes are down considerably, which aid to give Watertown an overall grade of average for its crime stats.
Watertown is home to 55 registered sex offenders. That is not quite a lot for the population of 25000 or so.
If you are concerned about this, see the website below.
As a tourist, it is up to you then to use diligence and common sense. Lock doors, watch the kids, don't go alone in to unfamiliar places. Be aware of who is watching you. If you are in doubt about the area, ask the hotel staff and they normally will steer you away from problem districts.
We go to Watertown on a bi-yearly basis and have not had any problems but we are out and about normally in the daytime only and with groups of friends in touristy places.
Winters in Watertown are horrendous.
Imagine 6 feet of snow accumulating in 48 hours. Or 10 feet in a week.
Snow banks along the side of the road are 9 feet high, you cannot see around the corners at an intersection (if you are lucky enough to have your car on the road instead of buried under feet of snow). And if that sounds pleasant enough, make the temperature be 4 or 5 degrees farenheit with a wind chill of -11.
Power lines are down in parts of the city so electricity is a bit iffy; trucks cannot make it into town so food stores are a bit skimpy; house roofs are collapsing from the weight of the snow.
That is a typical Watertown winter from January through March.
