Sediment deposition at the mouth of the Rifle River is interfering with navigation.
Sedimentation has increased turbidity and clogged gravel beds, reducing fish
reproduction habitat and invertebrate populations. Sources include streambank
erosion caused by ice, water and foot traffic, agriculture erosion, road crossings,
and off-road vehicles.
The Rifle River watershed is located in Ogemaw and Arenac counties, draining
an area of approximately 246,000 acres that outlets into Saginaw Bay. The
river itself stretches over 600 miles and its tributaries cover almost 140
miles. There are 29 inland lakes covering 2,564 acres. Much of the watershed
has a clay pan which results in rapid runoff. There are many high, exposed
sand banks, particularly in the lower portion of the river. The Rifle River
watershed is a popular recreation destination and hosts over 1,200 private
camp sites and numerous canoe liveries.
The purpose of this project is to demonstrate streambank erosion
control and promote the Rifle River Restoration Committee efforts. The Rifle
River Restoration Committee selected 10 to 12 sites to be targeted for this
project from the 354 erosion sites identified through the Rifle River Streambank
Erosion Inventory. Various erosion control techniques were applied including
rock rip-rap, tree revetments, bank shaping and seeding, and vegetative planting.
Under this project, six sites were identified for streambank stabilization:
Stoddard, River Bend Campground, Turtle Park, River View Campground, White's
Canoe & Campground, and Moffat Bridge Canoe Launch. Engineering plans and
designs were prepared and stabilization work was completed. A total of 1,750
tons of soil per year were saved as a result of this project.
Stoddard: Two hundred feet of streambank on state owned land were stabilized
with rock rip-rap and vegetation. A stairway to be used as a canoe launch was
installed and a natural groundwater seep outlet was stabilized. A total of 200
tons of soil per year were saved.
River Bend Campground: Three hundred feet of streambank
was stabilized with rock rip-rap, saving a total of 300 tons of soil per year.
Turtle Park: One hundred feet of channel was stabilized with rock
rip-rap and land shaping, saving a total of 50 tons of soil per year.
River View Campground: Eight hundred feet of streambank was stabilized
with rock rip-rap and vegetation, saving a total of 800 tons of soil per year.
Moffat Bridge: Completed stabilization of a canoe launch site and
diverted runoff from the driveway and road. One hundred and fifty feet of
channel and 200 feet of streambank were stabilized, saving a total of 250
tons of soil per year.
Whites Campground: One hundred and twenty feet of streambank stabilized
with rock rip-rap, saving a total of 120 tons of soil per year.
