PLAN DESIGN CONSIDERATIONS

Purchase of prefab or "homemade" cribs:

Technical Committee will explore a possible alternative involving utilization of prefab cribs to increase cost-effectiveness, ease of installation, and expedite project completion.

MN. DNR Fisheries will research MN. DNR policies/concerns over using non-biodegradable materials and if prefab cribs can be approved, will address any permit modifications or addendum's.

(1/14/99 Received word from MN. DNR Fisheries that State Policy requires utilization of log cribs.)

Navigational hazard considerations:

Per Special Provisions outlined in DNR Waters Permit # 99-1023, structures shall be placed in areas where tops of cribs will be at least 6 feet below the Ordinary High Water Mark. See: Attached DNR Protected Waters Permit.

(1/22/99 Current lake level will be determined within one week prior to cluster site mapping by a certified civil engineer from the North Central Minnesota Joint Powers Board.)

(2/19/99 Lake level survey completed.  Current water surface elevation is 1172.696)

See: Attached Joint Powers Board Survey Record.

Cultural, archaeological or historic resource considerations:

If any shipwrecks are located during site mapping or other stages of the project, all work will cease immediately and the St. Paul District will be contacted for further instruction.  All work related to this project will comply with General Permit Authorization and special Provisions outlined in U.S. Army Corps of Engineers Permit # GP-01-Mn.

See: Attached U.S. Army Corps of Engineers Authorization Permit.

(2/23/99 No indication of any shipwrecks was discovered during site mapping in cluster locations)

Methodology for determination of cluster locations:

Interview resort owners and "locals" familiar with the lake to determine their preferences of Cluster Locations based on sites known to historically contain target species of fish and possess desired qualities. This information, combined with navigational hazard, lakebed composition and structure considerations will contribute to final determination of cluster locations.  Once preliminary identification of cluster locations has been determined, a point-sampling methodology to record and map water depth, lakebed composition, and existing structural characteristics will be implemented. 

(1/12/99 Red Lake Department of Natural Resources has developed a Crib Project Lake Map to assist with identification of cluster site locations.  The GIS generated map details the Bathometric Survey, Creeks, Streams, Rivers, Judicial Ditches, Roads, and Section Lines on a Digital Ortho Quad background.  (Upon completion of preliminary cluster site identification, cluster center locations will be marked and recorded utilizing GPS technology.)

(2/21/99) Cluster Centers "flagged" using a combination of landmarks, mileage odometer and hand held compass.

(2/23/99) Locations of Cluster Centers "double checked" and confirmed using GPS prior to lakebed mapping.

Preferred existing lakebed structure:  (flats, rock piles, gravel bars etc.)

Lakebed structure is not a major factor in determination of cluster locations. However, structure should be recorded, and cluster locations should represent several different structural characteristics to enable future research as to structural relationships to crib effectiveness.

(Preliminary determination of lakebed structure will be identified by a combination of utilization of Crib Project Lake Map and interview of resort owners and "locals" familiar with the lake.)

(2/19/99 Interviews completed and Cluster Center locations determined).

Preferred lakebed: (sand, gravel, rock, muck etc.)

Lakebed composition is not a major factor in determination of cluster locations. However, substrata should be recorded, and cluster locations should represent several different lakebed characteristics and substrata compositions to enable future research as to lakebed relationships to crib effectiveness. 

2/16/99 Environmental Protection Agency donated use of Substrata Sampler to the Soil and Water Conservation District for this stage of the project.

2/23/99 Lakebed mapping completed by using the following methodology:

1) Preliminary cluster location sites marked on or near known structural changes.

2) Baseline point samples spaced 100' apart were used to locate substrata or lakebed elevation changes (5 point samples at each of 3 locations).

 3) Quadrants were established at right angles on both sides of the baseline, with point samples spaced 100 feet apart in 3 rows within each quadrant.

(24 samples in 2 Quadrants at each of 3 cluster locations)

* All point samples were numbered and information was recorded.

* At each point sample, an aluminum measuring rod was used to determine depth, and substrata composition.

* Substrata samples were taken at sample points representing typical and non-typical substrata composition.

A total of 87 point samples, including 9 substrata samples were recorded, covering a combined total of 16.5 acres.

Cluster Center locations were recorded by Forest Service using GPS accurate to within 1 meter.

See: Attached Cluster Site Maps.

Crib cluster design: (distance between cribs, aspect, relationships to structure etc.) Cluster design will be addressed upon completion of determination of locations and site mapping/data recording.  Three different cluster designs may be utilized to enable future research as to cluster design relationships to crib effectiveness.

The north cluster cribs were installed at 100 foot spacing.  The south cluster cribs were installed at 150 foot spacing.

The remaining center crib cluster is to be installed at 50 foot spacing and may incorporate two or more “mini-clusters” within the larger cluster.

Crib Design:

Cribs must be constructed in a manner that minimizes potential structural degradation resulting from transportation from staging area to final location, activities related to "sinking" the cribs, natural processes of material decomposition, and the potential of boat anchor "snagging".  In addition, potential future maintenance of cribs ("recharging" brush etc). will be addressed in crib design.  See: Attached Crib Construction Plan Drawing

1) Crib Dimensions-Cribs shall be constructed to final dimensions not to exceed 8 foot square and 6 feet high.

2) Species of Wood-Cribs shall be constructed with a combination of aspen and balm of gilead.  Tamarack was used on the first 40 cribs.

3) Log diameter, length, total volume of wood requirements. Logs shall be 100 inch length and no less than 7 inch average diameter, 22 logs per crib (43.5 cubic feet @ 45.6 pounds per cubic foot), approximately .55 cord per crib,
33 cords total.

4) Binding materials (spikes, staples etc.)-Pre-drill log ends and spike corners of each consecutive layer using 10 inch long "corkscrew"  spikes. Connecting surfaces of logs may be "flattened" to leave a minimum of 7 inches log end thickness. The bottom ends of the (four log) first layer may be beveled to facilitate transportation of completed cribs.  Pre-drill center of each log on all four sides in each consecutive layer, then "bind" all four sides by "threading" 1/4 inch diameter pliable-stock linear polyethylene through  holes, bend over ends and attach on top and bottom logs with 4 to 6 fencing staples on each end.

Regular 10 inch spikes were used, pre-drilling proved ineffective, steel banding was used to bind all four corners.

5) Crib bottom (wire mesh)-Crib bottom shall be 8 foot wide cement reinforcement mesh lain over the 4 base logs and 2 end logs, then partially wrapped around outer edges and attached with fencing staples every 6 inches.    Inside corners will have "block platforms" nailed over mesh to bottom logs to provide added  support during transportation of cribs from staging area to final locations.  Planned design of wire mesh crib bottoms was eliminated, and blocks were “built in” on two ends.

(10 linear feet mesh per crib, 600 linear feet total.)   (100 staples per crib, 6,000 staples total).

(6 each rough cut 1x4x8' green aspen "side lumber" per crib, 360 boards total)

(72 each 16 penny nails per crib, 4,320 nails total)

6) Weighting requirements (10" cinder block)-Each Crib shall have 28 blocks "wired" in clusters of 7 to each inside corner to provide equal weight distribution and offset buoyancy of logs.  
Prescribed number of blocks were used, but were “built in” rather than wired in.

(1316#/crib minimum).  (28 each 10" concrete cinder blocks per crib, 1680 blocks total)

(1 roll 16 gauge steel tie wire per crib, 60 rolls total)

7) Fill material (alder or willow brush)-Alder and Willow shall be cut in 6 to 8 foot maximum lengths and tightly "bundled" in 2 foot  average diameter bundles bound with several "wraps" bailing twine to facilitate transportation,   handling and temporary storage of fill material.
Crib "fill" shall consist of 5 "opened" bundles loosely packed in each crib.  Brush was hauled “loose” and not bundled, 
approximate volume of brush was as planned.
(5 bundles per crib, 300 bundles total)

8) Crib top (wire mesh)-Crib top shall be 8 foot wide cement reinforcement mesh lain over the 4 top logs and partially  wrapped around outer edges then attached with fencing staples every 6 inches. Wire mesh crib top was eliminated.  Brush was “woven” between log layers which sufficiently “bound” the tops.
(10 linear feet mesh per crib, 600 linear feet total.)  (80 staples per crib, 4,800 staples total).

Implementation Considerations:

Access points and Staging areas for materials, construction, and delivery of completed cribs:

Utilize three (closest possible) access points with minimal lakeshore slope.  Staging areas should be located as close as possible to access points. Staging areas should provide unrestricted access for tractor-trailer delivery of construction materials, adequate temporary storage of 20 completed cribs, and provide space for laborer parking.

Cribs were built “on-site” which eliminated need for staging areas. 

Potential pressure ridges:

Avoid hazardous areas to prevent accidents.  Any historically hazardous areas will be identified during the process of cluster location determination, and provisions will be made to minimize potential hazards during the process of installation.

(2/23/99) Potentially hazardous ice consisting of multiple stress fractures and pressure ridges were noted in several areas located approximately 1/4 mile from and parallel to the north shore.

Data Recording: (GPS coordinates, surrounding landscape features, lakebed etc.)

Individual crib locations shall be pre-marked within one week prior to crib installation to facilitate GPS location recording.  Lakebed recording will be performed during cluster location mapping.  Marking of individual crib locations will be as follows:N1, N2, etc., C1, C2, etc., S1, S2, etc. N = North Cluster,  C = Central Cluster.  S = South Cluster

1, 2, 3 etc. = Individual Cribs.

(12/29/98 USDA Forest Service will record individual crib locations utilizing a GPS unit accurate to within 1 meter.)

North cluster cribs were individually recorded south cluster corners were recorded.  (see attached)

Methodology for "sinking" cribs:

Place individual cribs directly on ice in pre-marked locations.  "Loop" 50 foot long guide ropes through each side of top layer to "guide" crib to lake bottom.  At a distance of 2 feet from the edges of the crib, utilize a chainsaw with an "ice chain" to cut within 1 inch of the water surface and then use ice chisels or hand operated ice saws to "break" block free.  This method will minimize water "splashing".  Once ice block has "broke free", use guide ropes to "steady" the crib.  Use pike poles to "push" ice from beneath crib to enable "guided sinking".

Ice thickness precluded planned installation methodology.  A loader truck was used to push the cut blocks below ice surface and to lower the completed cribs through the opening.

Thin ice marking: (signs, snow fence etc.)

Use "Thin Ice" signs placed 50' to 100' apart around perimeters of cluster locations to clearly mark for safety.  Lath and ribbon may also be installed around each hole to increase visibility. Use reflective signs. Leave signs up as long as possible, (end of Feb. or early March.) In addition, Cluster Site Maps will be posted at lake access points and supplied to local business for display.  

See: Special provisions DNR Waters Permit # 99-1023.

(12/29/98 MN. DNR Fisheries supplied sign manufacturer list used for DNR lake aeration projects, posts will need to be purchased separately.  The number of signs and posts required will be determined by cluster sizes.)

Thin Ice signs were posted, however spacing between signs and the number of signs was determined as inadequate/ unsafe by DNR Fisheries.

Implementation Considerations

Required ice thickness:

A minimum of 12 to 14 inches of "clear" ice is required prior to transporting cribs to their final locations.

Methodology for transporting cribs to final locations:

Temporarily attach "lift chains" to weight-bearing logs on bottom layer of crib.  Use a grapple-type loader truck to "grab" lift chains and place crib on dray.  Use at least 2 short lengths of chain held by chain binders to secure crib on dray.  Transport crib-loaded dray to pre-marked individual crib locations using 4 wheel drive pickup truck with tire chains, or tracked vehicle (bombardier or small crawler-tractor).  Use manpower to slide crib off dray at final location.

Cribs were built on site which eliminated need for transporting Project support recommendations: (includes but not limited to)

$1000,000.00 Liability Insurance.  Giziibii RC&D purchased policy, is effective until Dec. 2000

Liability Waivers (for access and staging area property owners, vendors, agencies etc.)  No liability waivers were used.

Contracts (vendors, service providers, crew leaders etc.)  No contracts were used.

A "warming" house for Crib Installation Crew and supplies storage.  No warming house was used.

Plowing vendor to maintain access and ice roads during installation. Nominal snow cover precluded need for plowing.

Crib transporting vendor (bombardier preferred).  Cribs were built on site.

Crib Loading vendor (loader truck)  Jack Bronczyk was hired to “push ice” and lower completed cribs.

"Flow Chart" designating duties and responsibilities.  No formal flow chart was used.

Project Coordinator.  Kelly Petrowske volunteered as construction/installation coordinator.

Procurement Agent.  One person was designated as procurement agent, all receipts were submitted.

Construction Crew Leaders. (hired Leader, volunteer crew)  Kelly and Harland Vitalis served as crew leaders.

Installation Crew Leader. (hired Leader, volunteer crew)  Kelly and Harland Vitalis served as crew leaders.

Public Relations Person.  Jerry Stensing provided media/public relations services.

Keep records of all paid and "in-kind" labor.  All workers time and equipment-use donations were recorded.

Follow-up study recommendations: (includes environmental/economic impacts)

Original funding request to Red Lake game Fund included financing a preliminary follow-up study.

However, request amount was not fully-funded so the follow-up study was “dropped.”

** Actual construction was of tamarack , with wire mesh and polyethylene omitted.  Cribs were constructed on the ice, “bound” together with regular 10” spikes and then reinforced with steel banding.  The cinder blocks were “built in” on two ends.   Due to extreme ice thickness, holes were cut completely through in two “blocks” which were then pushed under the ice by the loader truck to open the hole for crib installation. 

** Over 700 hours volunteer labor was donated by a total of 60 people to build and install 40 cribs.

** An additional 40 cribs in two more central locations are planned for installation during the winter of 2000.
