Further up the bay or river, the tide will not have reached its maximum height and water must therefore continue to flow in so that it can continue to rise. High water at a given point simply means that the level there will not get any higher. Tidal currents do not automatically slack and reverse direction when tide levels stand at high or low water. The apogean range (An) of the tide is the average range occurring at the time of apogean tides and is most conveniently computed from the harmonic constants. The time of occurrence of slack is not the same as the time of stand, when the vertical rise or fall of tide has stopped. Tides of decreased range or currents of decreased speed occurring monthly as the result of the Moon being in apogee. Conversely, a tidal current ebbs when the flow is seaward and the water levels fall.Īs these currents reverse, there are brief periods of no discernible flow, called slack, or slack water.
"A tidal current is said to flood when it flows in from the sea and results in higher tidal stages. Rivers and tributaries that feed the bay."
Have an overlaid outflow from the bay due to the
Have high/low tide concurrent with slack is that we Well here isĪn example where the slack and high tide does notĬoincide. The entrance it would slow down more and more.Įventually the current would stop (slack) but the tide Now if the river ran a bit slower theĬurrent would start to slow down as the tide came inįrom the ocean and as the tide continued to rise at So you have high tide and low tideĪnd no slack. The river but never have slack as the river is too fast To the sea it is likely that you would find tide in Send us feedback about these examples.That enters the ocean at high speed. These examples are programmatically compiled from various online sources to illustrate current usage of the word 'slack water.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. A King tide refers to the tide level only and as such anomalies in sea level due to non-tidal factors are not defined as King tides. 2019 The eight large dams along the Snake and Columbia rivers created 325 miles of slack water in reservoirs. Patrick Symmes, Harper's magazine, 28 Oct. 2020 The Columbia started to slow and broaden again, the slack water created by the 1957 Dalles Dam, which had buried the old Celilo Falls, a set of rapids where coho and Chinook had been caught with dip nets for thousands of years. Brian Maffly, The Salt Lake Tribune, 20 June 2021 From Pickwick Lake, high water has made many areas unfishable, but some anglers are connecting with catfish by drifting cut shad or skipjack just off the channels in slack water areas. Smith, Milwaukee Journal Sentinel, 29 June 2021 These trees are remnants of ecosystems that flourished along these canyon bottoms before the dam gates closed and turned the wild Colorado River into a 186-mile-long stretch of slack water in the heart of Utah’s redrock desert. 2022 The river in the slack water above the Thiensville dam drops off to between 8 and 11 feet in depth and is about 270 feet wide. Brian Maffly, The Salt Lake Tribune, 22 Mar. oregonlive, 17 June 2023 Instead these particles are piling up where the Green, San Juan, Escalante, aptly named Dirty Devil and smaller Colorado tributaries hit Lake Powell’s slack water. Slack water, which used to be known as the stand of the tide, is a short period in a body of tidal water when the water is completely unstressed, and therefore no movement either way in the tidal stream, and which occurs before the direction of the tidal stream reverses. 2023 These nutrient-rich fish, a wintertime staple for the Yurok people, lost 400 miles of their historical spawning habitat to four dams that transformed the churning upper reaches of the Klamath River into slack water, threatening the lamprey and other native species. Recent Examples on the Web Among golden aspens with bull elk bugling down the canyon, my Orvis Encounter rod and reel combo worked Adams dry flies past slack water to fish lying in wait, flawlessly. slack water, slack tide - Before any turn of the tide, there is a time of slack water or slack tide.
