In Moses Lake, it depends on what part of the lake the property is on. A standard 12' x 20' dock will run about $12,000 for for permitting, design and a contractor. If your in a portion of the lake that is really deep, you may need a dock with cantilever which could cost upward of $17,000-$20,000. Some areas of the lake are very shallow and need a really long dock.....again probably close to $16,000-$17,000. There are not really enough "like" sales to determine an actual "value" a dock adds, but most people do not want to go through the hassle of putting one in, so at this point, I would say an adequate size dock, in good condition, would add at least $14k-$20k. Right now, they are still issuing permits, but that may change in the next 6 months. If that is the case, a docks "market value" could go up significantly.
