April 30 - Tumwater Falls


I was awake at 3 a.m. with a sore shoulder and running a bit of a fever; presumably this is a result of the Shingles vaccine that I received yesterday.  A bit of a reaction to the vaccine is a bit of a hassle, but not nearly the agony of contracting shingles.  When I was a child, there was no vaccine for Chicken Pox, and parents used to get their kids over to visit other kids that had the pox, to get the disease out of the way.  I don’t know that the thought of people getting shingles later in life ever entered their minds.  In any event, I recommend getting your shots.
At 8:30, I drove over to Tumwater Automotive to have the oil changed on the CrossTrek, and have them do a safety check for my upcoming journey to Ohio and beyond.  While I was waiting for the job to finish, I walked down Capitol Way to do a bit of birding at Tumwater Falls Park.

The Park is owned and maintained by the Olympia Tumwater Foundation, and reflects the history and legacy of the Schmidt family, who used to own Olympia Brewing.  There are 15 acres of park land, with a loop trail along the river that overlooks all three waterfalls.

The crews are still working on the cleanup of the February transformer spill from the old brewery property.  PCBs are bad, I know.  But removing all of the streamside vegetation and scrubbing the rocks?

In spite of the disruption from the Dept of Ecology, this park is the best and easiest place in town to take visitors to see an American Dipper.  These wonderful sprites are passerines, which technically are birds that have feet adapted for perching.  Think Song Sparrows, wrens, swallows, warblers and the other birds that you see teed-up on a telephone wire, fence post or your garden rose.

The Dipper, though, is usually seen perched on a rock at the edge of flowing water.  Then, amazingly, it will just hop in and ‘fly’ underwater, popping up to the surface to eat the morsel that it pulled off the bottom of the stream, or swimming with its face in the water, searching for the next caddis fly larva.

Since I’m leaving early next week, I walked back to pick up my car and headed home to begin packing.

March 7 - Tumwater Falls oil and PCB spill


I dropped a car off in Tumwater, intending to walk home, taking the trails at the Tumwater Falls Park, the city of Tumwater’s Heritage Park, and along the south Capitol Lake trail.  However, the trails were blocked off, and considerable work was occurring along my planned route.
Construction work at WDFW Tumwater Falls salmon hatchery
At Tumwater Falls, there was a construction crew working on repairs to the 1953 WDFW Fish Hatchery facility.  Then, just below the upper falls, there were signs and barricades due to a toxic chemical spill.

According to the State Department of Ecology, an oil leak was caused by vandals at the former Olympia Brewery, attempting to steal copper from an electrical transformer to fuel their drug habit.  The spill from the former Olympia Brewery on Boston Street SW impacted the Deschutes River, and was first discovered on February 25th and stopped on the 26th.  The spill is believed to have entered the Deschutes River through a series of storm drains.

Authorities do not know exactly how much oil spilled, but the transformer had a capacity of 677 gallons.

The State Dept. of Ecology is waiting for lab results of oil samples that were collected at the spill site to help identify the product that was spilled. Transformer oil contains PCBs (polychlorinated biphenyls), a toxic chemical that gets into the food chain.  Although federal law banned PCBs in 1979, there are widespread reservoirs of this toxic chemical in old caulk, electrical transformers, fluorescent light ballasts, and paint.  Laboratory results show the oil contains less than 0.005 percent PCBs (approximately 30 - 50 parts per million).  State Department of Health toxicologist and PCB expert Barb Morrissey promises us that “…this spill does not pose an immediate public health threat.”
The Solution to Pollution is Dilution?
The Department of Ecology, the city of Tumwater, and Thurston County Health Department are working together with the owner of the brewery property on a cleanup plan.  Cowlitz Clean Sweep is the brewery’s cleanup contractor.

Sediment sampling is underway to determine the extent of contamination in the river, lake and connected culverts.
The steps to the base of the Lower Falls were closed off
Multiple lengths of oil containment boom are deployed between the spill site and down the Deschutes River into the north end of Capitol Lake.

Spilled oil is contained by using boom that floats on the surface of water. The boom helps concentrate oil so that it can be skimmed off the surface of the water and recovered in larger volumes. Skimming physically removes oil from the environment, allows for proper disposal and minimizes environmental impacts.
Boom at the Capitol Lake dam - keeping PCB from Puget Sound?
Apparently, Tumwater Falls Park re-opened today for the first time since the spill, however the park’s trail on the brewery side of the river remains closed.

Overall, the response is going well but is expected to continue for a while, according to Spills Program lead Alison Meyers.  As the website reported, “… the spilled oil does not pose an immediate public health threat. Cleanup crews continue to recover oil sheen from the water, and are wearing protective clothing because of their close proximity to the spill.
Upper Tumwater Falls
But, I did get to walk along the west side of the river at Tumwater Falls.  A Dipper was on a log below the upper falls.

As I watched, two Dippers visited a grass clump on the east side of the falls, and one of them entered at the base of the grasses. 
Who doesn't love Dippers?
Hopefully, this is a nest site for them.

I continued into the City of Tumwater’s Heritage Park, and indeed, the trail along the shoreline also remained closed.
Away from the water, the Canada Geese loafed, 

gulls hunted for earthworms,

and Robins fed in the woods.

However, the Great Blue Heron apparently did not get the memo about toxic PCBs contaminating her feed.

On my way back out of the park, I passed the Crosby House museum.  I’ve lived in this community for 30 years, and have yet to visit when it is open.

Leaving Heritage Park, I crossed under Interstate 5, finding the South Capitol Lake trail likewise closed.
I hope this path is re-opened by the time the warblers return . . .
So, I walked along the sidewalk to Percival Cove, which is an embayment of the former Deschutes River estuary that was dammed to create the Capitol Lake reservoir.

Mud and gravel from the creek is building up at its mouth, contributing to the sedimentation issues for the lake.

But, there must be good forage for the Ring-necked Ducks.
I left the lake for home, hoping that the oil spill clean-up is successful.
