Got Lamprey?

While they don't receive the same respect that other iconic anadramous species like salmon get, these amazing fish also migrate from fresh water out to the open ocean and back again. They formed an important food source for native population, although it is said they are an acquired taste.

Check out this video of LAMPREY SPAWNING on Mosby Creek. Mosby Creek is a tributary of the Row River. The Row River (pronounced like Cow, not tow) is a tributary of the Coast Fork Willamette River.

If you want to look for the lamprey yourself, take the opportunity to go for a bike ride from Cottage Grove on the Row River Bike Trail. The bike trail crosses Mosby Creek about three miles west of Cottage Grove. The trail from Cottage Grove to Mosby Creek is administered by the City of Cottage Grove, and the trail west of Mosby Creek is administered by the Bureau of Land Management. Enjoy!

Regarding ACOE Fill Permit Application for Retreat at Oak Creek


Late last week, it came to our attention that Landmark Properties, doing business as Retreat at Oak Creek, LLC, used our name in their application for wetland fill permits from the US Army Corps of Engineers and Oregon Department of State Lands (NWP 2013-68, pg 3). We would like to set the record straight, that we have no ongoing relationship with the developer. The last contact we had with the developer’s agents was prior to the annexation of the Sather property.

In response, we sent a letter to the Army Corps of Engineers to clarify our limited interaction with Landmark Properties.

In short, MRWC participated in a site visit at the request of Landmark Properties representatives.  We highlighted key ecological values of the site, specifically the oak grove and the unnamed channel on the northeast corner adjacent to Oak Creek.  The channel on that portion of the property is one of the few sites on Oak Creek which provides winter high flow cutthroat trout refuge and floodwater retention.  ODFW has documented juvenile Willamette spring Chinook rearing in the first mile of Oak Creek. 

At a subsequent meeting with Landmark Properties representatives, they shared their vision for the property.  The area and volume of wetland fill necessary to achieve their plans was not discussed at that time.


Two videos now available for download!
