Clark Plywood is the single largest industry in Spearfish Lake. It grew at the hands of Wayne Clark during the depression as Wayne managed to purchase much timber land around town. It was with demand from World War 2 that ensured its success. Lumber and wood products have long been the mainstay of the economy in the area, but Clark Plywood specialized, at least until 1984 when they stopped actual plywood manufacture.
In more recent times, Ryan Clark, grandson of Wayne, now runs the business with Steve Augsberg, his production manager. As the company is closely held by the Clark family, they must be counted as among Spearfish Lake's wealthiest, yet it is not liquid wealth.
- Ryan had tried to bring young, well-trained, and experienced professionals into management positions when he could, looking to give the company solid management in the years when Randy would have to bear the ultimate responsibility at something of a distance.BHF3
