Spruce Railroad Trail Improvements to Begin August 5
Spruce Railroad Trail will be closed from the Lyre River TH to approximately 0.25 miles east of Devil’s Punchbowl. Work is expected to be completed by the end of October. The remainder of the trail will be accessible from the Camp David Jr. Road TH. More »

Rabies has been detected in a single bat in the Lake Crescent area of the park. Rabies exposure is extremely rare, but fatal if untreated. Anyone observing unusual or aggressive behavior among park wildlife should inform a park ranger as soon as possible. More »
Elwha Water Facilities
The Elwha River Ecosystem and Fisheries Restoration Act of 1992 requires “protection of the existing quality and availability of water from the Elwha River for municipal and industrial uses from [the] possible adverse impacts of dam removal” (Section 4(a)(3)). In the 90-plus years since the dams were built, large amounts of sediment have accumulated at the bottom of the two reservoirs, most of it in a delta at the head of Lake Mills. Extensive testing and modeling has shown that protection measures are necessary to meet the requirements of the Elwha Act.
Elwha Surface Water Intake:
The Elwha Water Treatment Plant:
During high turbidity, it would allow the city to turn off the Ranney collector pumps to prevent plugging of the subsurface gravels. When times of high turbidity pass, the city could again send water from the Ranney collector to the PAWTP. Water treatment for the Lower Elwha Klallam Tribe fish hatchery and the WDFW rearing channel is necessary in order to protect anadromous fish stocks. The EWTP will supply filtered water for the hatchery and rearing channel in order to protect the fish from adverse conditions that may likely arise during dam removal. During dam removal, a portion of the rearing channel production of Elwha Chinook salmon will occur in off-channel ponds near Morse Creek.
The high sediment transport period is expected to last from three to five years, depending on stream flows during that time. Higher stream flows would erode the sediments downstream faster than lower flow periods. The EWTP will only operate only during this three to five year period.

Did You Know?
Although related to other marmots and groundhogs of North America, the Olympic marmot is unique. An endemic species, it is found only in the Olympic Mountains. Visitors to the high country of Olympic National Park may be lucky enough to encounter a marmot sunning itself near its burrow.
