As of this morning The Santa Clara Valley Water Disrtict is increasing the releases from Stevens creek to 250cfs and at noon they will increase the flow to 350cfs depending on the inflows from the storm. There is a chance that the reservoir could spill later today or by Friday depending on these inflows. This is huge because normal flows are a mere 3 to 6cfs in the summer and less than 60cfs in the winter in a normal year.

With the advent of current storms the Santa Clara Valley Water District has informed me that they will be opening Stevens creek reservoir to 100% open at noon on Sat. 3/19/11 and the reservoir could spill tonight or early Sun. morning.

Please be very careful out there!

With the scarcity of open space lands here in this heavily urbanized valley, the remaining lands along Stevens Creek are under more and more pressure for development. Multi-use trails, picnic areas, ball fields, community farms, BMX dirt jumps and dog parks are all being discussed as possible developments. At the same time, though, the creek and associated riparian and upland habitats are part of a vital, but shriking wildlife resource. Many people are not aware that the human disturbance associated with public access to creek areas affects habitat quality. In particular, impacts from the use of recreational trails are greatly underestimated.

We live in a valley full of bright, productive people who care about the quality of life in their community and are willing to put in many volunteer hours to achieve goals they believe important to community welfare. The differing goals for the limited remaing open lands along Stevens Creek make for a somewhat uncomfortable situation, but also offer opportunities for creative thinking. How can we both meet the needs of the community and protect needed wildlife habitat?

I know there are many folks out there with strong opinions about what we should be doing in and with the Stevens Creek Corridor. I hope you will share your thoughts here – it may be that nothing positive will come of it, but it may also be that something surprising, beautiful and original evolves

Along with Blackberry Farm, the bit of Cupertino-owned land known as the Stocklmeir Orchard was studied as part of the Stevens Creek Corridor Project. This land is scheduled as Phase II of the overall project, with plans currently calling for re-alignment and restoration of the creek. Also planned is the installation of an eight-foot wide multi-use trail through the property connecting with other parts of the Stevens Creek Trail.

Cupertino Parks and Recreation staffer, Julia Lamy, has organized a task force of local stakeholders to provide input into the planning process. Some residents have concerns about the original plans as well as new ideas as to how the property could be rehabilitated and used. One of the ideas is to establish a community education program centered on the care and cultivation of the legacy orchard. Another idea is to protect and enhance the riparian and upland habitat of this creek-side property. 

The stakeholders have different values and sometimes competing interests, but expect to move forward in the planning process to find consensus.  By no means are all points of view currently represented on the task force and they are seeking to expand participation. The next meeting is scheduled for June 9^th at 2:00 pm in the conference room of the Quinlan Community Center.

(Cupertino, California) McClellan Ranch has not had a change of habitat. SWAMP is the Surface Water Ambient Monitoring Program that Eric Burres of the California State Water Resources Board discussed with us on Wednesday April 8, 2009 at McClellan Ranch. I was not able to join the daytime field training, but the evening lecture was well attended by the SPCWC bug loving community and students who confessed they “just love bugs”.

Mr. Burres began by relating the importance of the concept of biological integrity. “Clean water is not enough,” he told us. We are required by the Clean Water Act to strive for biological integrity which is defined as “the ability to support and maintain a balanced, integrated, and adaptive community of organisms having a species composition, diversity and functional organization comparable to those of natural habitats within a region” (Karr, J. R. and D. R. Dudley. 1981. Ecological perspectives on water quality goals. Environmental Management 5: 55-68).

With the scarcity of open space lands here in this heavily urbanized valley, the remaining lands along Stevens Creek are under more and more pressure for development. Multi-use trails, picnic areas, ball fields, community farms, BMX dirt jumps and dog parks are all being discussed as possible developments.

We were then treated to the introduction of Ralph and Lisa Cutter’s BUGS OF THE UNDERWORLD video that features remarkable video of a variety of fish and benthic macroinvertebrates in their natural submerged enivronment. As I watched stoneflies, caddisflies, damsel flies, midges, crawfish and lobster swish and crawl across the screen, I was reminded of the remarkable genius of nature. I came straight home and ordered a copy!

I hope that you will be able to join us at future events and get involved with our Bug Club. I suspect we all have an inner taxonomist just waiting to molt an exoskeleton and fly.

Our partnership with De Anza college has lead to the discovery of highly toxic water in Stevens Creek.

Our first test included a site below the outfall at Stevens Creek Blvd.  The current thinking is that the cause is a substance called pyrethroid which is found in insecticides employed for ant control.  Site SCB511 is the toxic site.

Here is a graph of our results, using the method described under Projects, Water Quality Monitoring, Toxicity Testing. The test takes advantage of the sensitivity of a strain of bioluminesent plankton to toxicity they get dimmer as water quality deteriorates.

Members of the Water District, Stormwater Program and Santa Clara County visited the site we reported here and have referred the problem to code enforcement.

We will continue to follow up till we get resolution to the problem.

We still don’t know why the water was flowing a reddish color.

Well the rain has finally come with enough water to make a difference, both good and bad.

Mondy and Michael B. went out to have a look on Monday the 16th to see what they could see.

Our first stop was the parking lot of the Sunnvale Gun Club and just as it has in years past a steady flow of off-color water is coming from under the stone wall and streaming down the road and then eventually into the creek below the dam.

Next we visited the creek near the point where it empties into the reservoir, and it is really flowing dark and fast.

We also surveyed the reservoir which has risen over 12 feet in the last three days.

Next we stopped at Chestnut area and McClellan Ranch then down to the West Valley School Bridge and the Fremont fish ladder.

The stream is finally continuous down to the bay, and, with any luck, steelhead can now make the trip up to their spawning grounds.

We could hardly believe the amount of water down at La Avenida and so we looked for signs of fish at the Moffett ladder which looks to be operating.

We ended with a visit to the Central Avenue Fish Ladder which is finally operating after a long dry spell for that area of the stream.

I took photos of all of our journey, which you can view on the website by clicking here and here.
