Removal of Artifacts Prohibited at Scoggins Valley Park

The water in Hagg Lake serves many purposes including irrigation water for agricultural lands and drinking water for hundreds of thousands of Washington County residents. As water is used the reservoir level drops. Lower-than-normal reservoir levels may expose artifacts and other items and removing historic and cultural artifacts from reservoirs or any other federal lands is strictly prohibited.

 Hagg Lake Water Quality Update


UPDATED: 07/20/2021


Today, July 20, 2021, Washington County Facilities and Parks Services learned that cyanotoxins associated with seasonal Cyanobacteria (harmful algae) blooms were not detected in water samples taken on Thursday, July 15, from five separate locations around Hagg Lake. As recommended by the Oregon Health Authority (OHA), the samples were tested for four different cyanotoxins that could pose a health risk to people and pets recreating in bodies of water. Locations included Bobcat Cove, C-Ramp Recreation Area, Dam Overlook, Eagle Point Recreation Area and Sain Creek Recreation Area. All tests were negative for Anatoxin-a, Cylindrospermopsin, Microcystins and Saxitoxin.


Although these findings are very encouraging, Washington County continues to urge visitors to Scoggins Valley Park to use caution when recreating in Henry Hagg Lake—or any body of water—and be very familiar with Cyanobacteria blooms and related health concerns, especially when accompanied by children and pets.
