Source-derived summary

Conconully Dam (National ID # WA00259) is a dam in Okanogan County, Washington, United States.

The earthen dam was initially constructed at a height of 70 feet (21 m) in 1910 and 1911 by the United States Bureau of Reclamation, during the first generation of the Bureau's activity, then raised in 1920 and reconstructed in 1969. The dam's current height is 72 feet (22 m) and it is 1,075 feet (328 m) long at its crest.

Conconully Dam impounds Salmon Creek for flood control and irrigation storage, part of the larger Okanogan Project. It was listed on the National Register of Historic Places on September 6, 1974. The adjacent 1921 Salmon Lake Dam and its reservoir, Conconully Lake, are also part of the same project. Both are owned by the Bureau and operated by the local Okanogan Irrigation District.

The Conconully Reservoir has a normal water surface area of 550 acres (220 ha) and a maximum storage capacity of 13,000 acre-feet (16,000,000 m3). Recreation includes fishing (for rainbow trout, cutthroat trout and smallmouth bass), boating, camping, hiking and wildlife viewing. Conconully State Park and Conconully National Wildlife Refuge are also nearby.

Editorial analysis

Why this record matters

The phrase “place in Washington listed on National Register of Historic Places” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 4, 2026. The linked authority identifier is Q5158741. The first chronological checks are 1910, 1911, 1920 and 1969.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
