Stonepick Crossing

From the publisher: Stonepick crossing is an OSRIC(tm) module designed for 6-10 adventures of levels 1-3. The tiny town of Stonepick Crossing sits on top of an old dwarven dam holding built some 500 years ago to end a long war. Recognizing the futility of direct assault, the dwarves built the dam to flood the goblin caves, flushing the foul creatures out of their caves and into the slaughter of honest combat. Now 500 years later, the dwarves have moved on and a small thorp has sprung up. Mystery surrounds the protected town and rumors abound: locals disappearing in the middle of the night, strange noises from underneath the dam and even rumors of a monster in the lake percolate through the community. Which rumors are true and which are the ale-addled ramblings of old men fearful of their own shadows?
