Mecan River Workday July 2011 Mecan River Workday July 2011 Placing rock on top of bank cover Rock is place on the outer edge of the bank cover to help hold in in place and to provide a natural edge to the bank cover and help prevent erosion after the bank cover is covered with fill. In the foreground is Dylan Shetellenberg from the Elliot Donnelly Chapter of TU and shown standing behind him is Elward Engle. Elward, retired from the DNR, has a lot of experience working on trout streams and is usually present to help at many of our work days. 131996616 The Good and the Bad One of the hazards of stream improvement work is coming in contact with Poisen Ivy or Poisen Sumac. To the right is a Poisen Ivy plant that was very abundant along the river channel where we were working. To the left is a Jewel Weed which has great healing properties and if you split the stem and rub the juices onto your skin it can help prevent or reduce the skin irritation of the Poisen Ivy. Jewel weed can also be rubbed on your hands to reduce cracking and splitting or other skin irritations. 131996617 Nailing Down the Planking Shown in the picture are left to right: Linn Beck (CWTU President), Steve DeWitt (DNR Habitat Crew), Ira Giese and Tracy Moran (kneeling), Rich Scamehorn, and Dennis Drazkowski. 131996618 Nailing Down the Planking The planking is nailed down onto the log pilings that are jetted into the bottom of the stream using large ring shank pole barn spikes. Shown to the far right is Arturo Cisneros from the Elliot Donnelly Chapter of TU from Chigago. 131996619 Nailing Down the Planking Thick rough sawn planking is nailed down onto the pilings. Planks are first nailed from the outside plank to the inside plank and then planks are nailed over these to form form the bank cover. 131996620 Cutting the Planks to Length Shown from left to right are Chris Northway, Scott Bahn, Tracy Moran, and Steve DeWitt. 131996621 Bank Cover Ready for Next Steps This is what the bank cover looks like with all the planking attached. A quarter of a log will need to be attached to the outer edge to help keep the rocks that will be placed on top from sliding off. 131996623 Good Equipment Really Helps Shown to the left is a Track Vehicle that is used to haul materials and equipment to the stream. It also holds the compressors and pumps used to jet in the pilings and operate the underwater chain saw. 131996624 Jetting in the Pilings About 6 foot long logs are jetted into the stream bottom by using a long pipe attached to a hose and water pump. The force of the water makes a hole in the bottom and facilitates sinking the log into the bottom. Shown left to right are Shawn Sullivan (DNR Habitat Crew Supervisor), Jeff Wegend, Phil Lubke (DNR Habitat Crew), Mike Niemczyk, Arturo Cisneros Jr., Dylan Shetellenberg, and his grandfather from the Elliot Donnelly Chapter in Chicago, Bill Wobberkind. 131996625 Jetting in the Pilings One person uses the forced water to make the hole and help sink the log, while another crew member uses all their weight to help sink the log into the hole as deep as possible. 131996626 Jetting in Pilings Shawn Sullivan, the DNR Habitat Crew Supervisor is shown on the left removing a large rock that was in the way of where he wanted to sink the log. Linn Beck in the middle is holding the next log to be sank, while Scott Bahn is shown holding the last log that was sank so that it stays in place until the sand fills in around to hold it permanently. 131996629 Removing the Larger Rock This crew is working ahead of the crew sinking the logs and they are using pry bars to locate and remove larger rock that might get in the way of sinking the logs. Shown left to right are Arturo Cisneros, Mike Niemczyk, and Jeff Wegand. 131996630 Bringing in the Heavy Equipment There was a rock to large to be moved by hand, so Shawn Sullivan brings in the heavy equipment to remove it. 131996628 Removing a Large Rock Removing a large rock where we needed to place a log. It sure helps to have equipment like this as it makes it faster and safer. 131996627 Cutting the Logs to Proper Height Phil Lubke (DNR Habitat Crew), is shown cutting the log the the proper height with a special chain saw that operates under water. The saw uses biodegradable food grade hydraulic oil so that it does not pollute the water. All equipment used in the water including the Track vehicle and regular chain saws use biodegradable oil. 131996631 Sunken Logs and Planking This picture shows the sunken logs cut to the proper height below the surface and in the background, the first set of planking attached to the logs. 131996632 Bank Cover with Edging This shows the bank cover with the quarter log attached to the edge to keep the rocks from sliding off. The water will scour under this bank cover providing a deeper cover for the trout to hide. It provides protection from the birds such as kingfishers and herons. Large branches and small logs are placed under some bank covers to provide a place for fish to hide so the otters cannot get them. The brances are placed so that the fish can get behind them, but the otters cannot get through them. 131996633 Finish Bank Cover Ready for Fill This shows the finished bank cover ready for fill. You will also notice planking on the inside of the bank cover placed on end and jetted into the bottom. This is done to prevent soil from the bank and stream bottom from eroding from behind. This will be covered with fill and seeded in and the outside of the bank cover will be the new edge of the bank. This bank cover reduces the stream width where is had widened do to bank erosion and will help increase the flow and scour the bottom to deepen the stream in that area. The deeper water also helps reduce stream temperature where sun light penetrating shallow areas warms the water. 131996634 Time to Relax and Enjoy Some Good Food Most work days are followed up with a great lunch served on site. Shown second from the left is Dan Harmon III serving as camp chef for the day. This also provides a good time to relax and sometimes talk about fishing. 131996635
