Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...
The following list of known freshwater fish species, subspecies, and hybrids occurring in Washington state is taken from Wydoski and Whitney(2003). Some scientific names have been updated or corrected. Trout nomenclature follows Behnke et al.(2002). Asterisks denote introduced fishes.
A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).
This is a list of natural lakes and reservoirs located fully or partially in the U.S. state of Washington. Natural lakes that have been altered with a dam, such as Lake Chelan, are included as lakes, not reservoirs. Swimming, fishing, and/or boating are permitted in some of these lakes, but not all.
South Jetty of the Columbia River under repair in 2022. The bar is where the river's current dissipates into the Pacific Ocean, often as large standing waves. The waves are partially caused by the deposition of sediment as the river slows, as well as mixing with ocean waves. The waves, wind, and current are hazardous for vessels of all sizes.
Barview: Lupatia: 3 January 1881: A barque that sunk with the loss of the 16 man crew. The only survivor was the ship's dog. [5] [6] Tillamook Rock: Kate L. Heron: 27 April 1881: A schooner that was wrecked on Tillamook Bar. Parts washed up at Nehalem. Barview: Pilots Bride: 1 August 1881: A sloop that was stranded on Nestucca Bar. Pacific City ...
Tide flow information is most commonly seen on nautical charts, presented as a table of flow speeds and bearings at hourly intervals, with separate tables for spring and neap tides. The timing is relative to high water at some harbour where the tidal behaviour is similar in pattern, though it may be far away.
Washington State Commercial Passenger Fishing Vessel Association, 443 U.S. 658 (1979), was a United States Supreme Court case related to Indian fishing rights in Washington State. It held that the usual and accustomed clause of the Stevens Treaties protected Indians ' share of anadromous fish in addition to protecting fishing grounds.
