A Columbia River Anchor System typically consists of the following:
Rocker Style Anchor, 20 – 40 lbs. Also referred to as a Rocking Chair Anchor or Columbia River Anchor.
3 – 6’ of Chain, or more, typically 5/16” – 3/8”
300’ of 3/8” Solid Braid Nylon Rope. The amount of rope used depends on the current speed and water depth and other factors. The general recommendation is to use approximately 7 times the water depth. Example: 10’ of water = 70’ of rope, but again, it depends on many factors including the loaded weight of your boat, current speed, etc.
Buoy Ball, size needed will vary depending on rivers fished
Anchor Puller, attached to the Buoy Ball.
Anchor Nest mounted to the bow of the boat, often called an Anchor-Caddie, Bow Anchor Holder, or any other device used to keep your Anchor secured on the bow of your boat.
A Cleat to secure your rope while on Anchor
The above is just an example of a typical River Anchor System, but can and will vary depending on river conditions, type of boat and personal preference, but these are the basics.
The Columbia River Anchor System is not only designed for the Columbia River, but can be used anywhere where you are subject to consistent water-currents.
Other places to use the Columbia River Anchor System would be:
Snake River in Idaho fishing for Salmon or Sturgeon
Frazer River in Canada
Sturgeon Fishing in Europe
And any of the other countless rivers on the planet
