While fishing in Canada I saw some interesting structure. They were basically square cribs made of 6 to 8" diameter logs, then filled with volleyball sized rocks. They were usally placed in a reef formation going from shallow to deeper water. The yellow perch, smallmouth bass, and rock bass loved these things!

Where these completely submerged? I noticed this construction method was pretty common for docks and breakwalls.

Yes, they were completely submerged and most were located in 5-10 feet of water. They seem to be quite labor intensive to make, but very long lasting and the fish really seemed to enjoy them.

Iowanate, I would imagine those were abandoned dock cribs? The docks have probably long since washed or blown away, and the cribbing remains.
In most areas, if the owner does not remove the dock, the winter ice will destroy it.

Rattletrap2, they very well could be old dock cribbings as they were usually oriented in a straight line. Either way, it sure attracted the Canadian bass and yellow perch in large numbers!

Side Question: Why don't pond owners use a crib to create their dock? Not enough nature force to worry about it? Or is it because most build their docks at the beginning of construction?

I think it would take more labor and materials and most of us probably don't have enough basketball size boulders laying around. Buying boulders would probably really expensive. From my limited experience, the docks constructed by this method weren't very level or smooth either. I do think the fish would like them though.

There are different types of cribs (look different). Dock cribs look like the one RobA posted (good link RobA). There are also fish cribs (I will find some pics). Both dock and fish cribs are great structure. Here is a link. Crib is another name for fish structure and has many forms. Here are some. Most use logs or pallets. Some have rocks some brush some are open. http://www.chetek.com/clpa/cribs.htmHabitat Manual for Use of Artificial Structures in Lakes and Reservoirs Compiled by the Southern Division AFS Reservoir Committee Log Cribs Log cribs consist of square log structures and may contain several layers of brush (e.g., Wisconsin log crib). Click here for map of states that used this method. Main reasons used: - availability of materials - low cost - preference for natural materials - longevity - ease of construction and installation - interest of anglers Reported advantages: none reported Reported disadvantages: none reported Recommendations: none reported Mean reported time to create/place one structure/unit: 17 hrs (range 0.25 - 60, n=4) Mean reported life of structure/unit: 25 yrs (range 15 - 50, n=4) Degrees of Satisfaction: **average ratings on a scale of 1 - 5 with 1 being very satisfied and 5 being very dissatisfied. - fish attractor to increase angler catch and harvest 1.0 (n=2) - recruitment 1.0 (n=2) - adult habitat/sanctuary 1.5 (n=2)

Photos 4, 5, and 6 were exactly what I have seen in Canada except the cribs were filled with large rocks. And given that they should last about 25 years means great fish habitat for a generation.
