A PA-32R pilot reported running off the end of the wet runway at his home airport because he was concerned about power lines and trees at the approach end; and flew a deliberately high approach path.

Narrative

As [my destination airport] is my home base; I am familiar with the trees; power lines; and inoperative VASI'S for at least the last few years. I used [another nearby airport's] altimeter settings and winds. I set up for landing and called out on CTAF for the downwind; base; and final with my normal power settings; landing gear down; fuel pump on; landing lights on; propeller high; mixture rich and full flaps. I was deliberately higher than normal (daylight) approach as my concern with the power lines and trees. My speed [and] power settings were [as in] normal approach. Once I was sure I was clear of the power lines and trees; I brought the plane to the runway and touched the mains then the nose wheels for a normal soft landing maintaining center line control of the runway. Winds were not a factor. The runway was wet. I went off the end of the runway approximately 15 FT where there is a small creek. The nose of the plane stopped in the creek. There were no injuries (other than my pride).
