OverviewExcerpt from Evaluation of Water Table Conditions Within a Grove of Picea Sitchensis, Hoh River Visitor Center, Olympic National Park, Washington In the vicinity of the Hoh River Visitor Center, an impoundment on Taft Creek (created by road construction during the 19608) inundates an area near old growth Sitka Spruce (figure Since that time the spruce trees in the vicinity of the pond have exhibited unhealthy tops, thin foliage and reduced growth rings. The trees presently do not contain much rot, but premature loss of the trees is expected if their stressed condition continues (ed Schreiner, personal communication). It has been hypothesized that wet feet or excessively high ground water around the roots of the trees is causing the growth stress. The Hoh Indian Nation and State biologists have identified the pond as coho salmon rearing habitat. These entities have informed the park that attempts to drain the pond would be detrimental to the fisheries resource. The primary issues confronting park management are 1) the cause of tree growth stress and the relationship, if any, to water conditions, 2) the influence on ground water conditions from the Taft Creek impoundment, and 3) available options for correcting any perceived threats to the trees.
