From time to time, the Mill Valley StreamKeepers plans activities open to the public in order to educate our citizenry of the needs of our watersheds, to encourage residents to preserve and protect them, to take part in a constructive activity and to have an enjoyable day, usually in the great outdoors.
In the past we have held stream Clean-Up Days, in which we participated in removing exotic plants and debris from our creek beds; led Creek Walks that followed a Mill Valley stream path and included an instructive discussion by a StreamKeeper; and participated in civic functions to spread the word about our organization and its goals.
Mill Valley Beautification Day - April 21, 2007
The cloudy skies did not dampen the spirits of over a hundred community volunteers as they picked up litter and removed invasive plants last Saturday – all in an effort to beautify and enhance Mill Valley in honor of Elizabeth Terwilliger (“Mrs. T.”) and Earth Day. On Saturday, April 21st, groups such as Rotary, Bloomathon, Scouts, StreamKeepers, and Little League spread out among the parks and streets of Mill Valley to collect litter and protect important local habitat.
StreamKeeper volunteers in hip waders patrolled Corte Madera Creek for trash and found the entire front fender of a car. The Girl Scouts and environmental artist Jeff Hvid pulled bikes, balls, tires, and over 300 pounds of glass bottles from Goodman’s Marsh. Read more >
2007 Steelhead Spawning Surveys
Volunteers walked Mill Valley streams from January to March 2007 to look for signs of steelhead migration and spawning.  The purpose of the survey was to determine the presence of steelhead trout migrating into the Arroyo Corte Madera watershed during the winter spawning season, observe their spawning behaviors, and monitor steelhead interactions with culverts thought to impede migration.
Steelhead, the anadromous (sea-going) form of rainbow trout, are surprisingly adaptable to the urban environment and have been found in a number of Bay Area streams. In Mill Valley's Arroyo Corte Madera, steelhead have been reported as high up in the watershed as Old Mill Park. Steelhead are born in the upper reaches streams, rear in freshwater 1-3 years, migrate to the ocean where they mature to adulthood, and return to natal waters to spawn. In Marin, spawning generally occurs between January and March, 2007.
Fisheries biologist Gary Reedy trained volunteers in monitoring protocols. This study was funded by the Marin Municipal Water District's Will Evans Watershed Habitat Improvement Grant Program.

 On February 18, 2006, a panel of experts - Fishery Biologist Bill Kier, Aquatic Ecologist Eric Ettlinger, Botanist Phyllis Faber and Stream Ecologist Gary Reedy - appeared at the Mill Valley Library for an event entitled "Mill Valley's Streams: Tame or Wild?." They discussed our streams and their suitability for the return of Coho and Steelhead Salmon.
 On October 25 2005, Naturalist of Muir Woods National Monument Mia Monroe shared her years of observation of the Spotted Owl in Mill Valley and Muir Woods. She discussed native plantings and stream bank restoration that encourage native wildlife.
The event was held at the Mill Valley Library Creekside Room, and was sponsored by the Mill Valley StreamKeepers and the City of Mill Valley.
February 8-14, 2004, was Mill Valley Watershed Appreciation Week, and the Mill Valley StreamKeepers played a major role in it. The StreamKeepers unveiled a sign, Life in our Watershed, on the path in Bayfront Park, at the first bridge south of Sycamore Avenue.
Following the ceremony, a program and exhibits were opened to the public at the Mill Valley Community Center. There were speakers, exhibits of students' work, maps and watershed-related computer resources including krisweb.com.
A Creek Walk along Old Mill Creek began near the Mill Valley Public Library with a talk given by StreamKeeper Andy Peri (photo below). The walk continued along Old Mill Creek toward the Cascade Canyon area. We are in the process of planning our next Creek Walk, and more detailed information will be presented here when the event is finalized.
