  Slack Water Walleyes
Walleyes like the slack water areas to feed and rest from the force of the current.
They also like to be in shallow water where most of the food supply is at during the winter months.
Approaching walleyes in these slack water areas is a lesson in stealth.

  Canals
Puddle is used to separate the water of a canal from porous strata, and is placed in ditches to prevent water from spreading away from the canal, and to stablilize embankments.
Water passages are made from the upper reach to the lock chamber, and from the lock chamber to the lower reach, with a gate, called a paddle, that is raised or lowered by a rack and pinion to open or close the passages.
The amount of water required for the passage of one boat is determined by the largest lock, so the rise of the locks on a canal is made as uniform as possible.

 Slacks   (Site not responding. Last check: 2007-10-26)
Slacks are notoriously difficult to predict, and rely mainly on local knowledge from the "old salts" and people who are out there every day.
In this example the slacks are at almost identical times for springs (the blue line) and neaps (the magenta line), but this isn't always the case and is why we need to plot both of them.
However, if you want a slightly more accurate indication of the diveable slack for a particular day, then look up the mean spring and neap ranges for the port in question, calculate today's tidal range, and then put those figures into a second spreadsheet which will plot today's slacks for you.

 Tidal Currents
As the tide comes in, the water entering the bay has to overcome slow water to move forward into the bay (viscosity) so this change is not seen at the other end of the bay immediately.
The water level once again changes first at the bay's entrance while the water further in the bay may still be at high stand.
The water flowing from the river will tend to hinder the movement of water into the river, hence causing the flood current to be less swift.

 Regulating Mississippi River Navigation Pools Brochure
A dam is formed when the gates are lowered, causing the water level upstream of the dam to rise and form a slack-water pool deep enough for navigation.
Except for the water that goes into valley storage as the inflows increase, all inflow must be discharged.
When the river has been in open river flow condition and the pool elevation at the dam falls to the secondary control elevation, the gates are returned to operation and secondary control elevation is maintained at the dam until the stage at the primary control point has fallen to project pool elevation.

 IHE Delft - Dicea   (Site not responding. Last check: 2007-10-26)
When the tide approaches slack water, and the velocities are low enough the caisson is sailed into the closure gap and sunken down.
In general placement during low water slack is preferable, because during low water slack the required sinking time is less.
During high water slack sinking is also possible, for example when the waterdepth above the sill is too small or when every slack water has to be used to speed up the total closure period.

 Ground Water in the Alexandria Dunefield and its Potential Influence on the Adjacent Surf-Zone   (Site not responding. Last check: 2007-10-26)
Water quality of the ground water in the Alexandria dunefield was monitored with the aim of estimating the amount of nutrient input from this source into the adjacent surf-zone.
Nitrate concentration in the water was measured according to the method outlined by Bate and Heelas (1975), ammonium by the method of Solarzano, (1969) and soluble reactive phosphorus by the method of Strickland and Parsons (1972).
The soluble reactive phosphorous content of the ground water taken from both the front and back of the slacks showed little difference during any of the 24 h periods or between the 3 d on which measurements were made (Fig.

When those tides occurring near the equinoxes when the full or new moon and the sun have little or low declination and spring tides of greater range than the average occur, particularly if the moon is also nearly in perigee.
It may be called high water stand if it occurs at the time of high tide, and low water stand if it occurs at low tide.

 07. Olga Bay, Tides in Bays, Mathematics
But all this aside, I saw that the times of slack water were typically well after the time of high or low tide, as in 25 to 45 minutes.
In the above graph, the slack water times occur when the example green and blue lines (bay water heights) cross the red line (ocean water height), which are the times when the ocean water height and the bay water height are equal.
A primary clue that a bay will show a long slack water delay after high and low tide is the presence of relatively small tides inside the bay, compared to reference ocean tides outside the bay.

 Slack-water times
These can further affect the "slack" times so the golden rule is: once you've calculated the theoretical time of "slack", plan to arrive early; it's better to sit and wait twenty minutes than to miss the dive!.
Dropping from the green band are yellow and maroon lines, these show the diveable periods around "slack", yellow for springs and maroon for neaps.
Most importantly you can see when the diveable periods start - for "low water slack" from about 5 hours twenty minutes to 5 hours before high water at Tynemouth and for "high water slack" from about 50 minutes to 1 hour twenty minutes after high water at Tynemouth (for neaps and springs respectively).

 Pocket Water Trout Fishing
Pocket water is characterized by having fast turbulent runs and riffles cutting between steep river banks, and the fish that are in this pocket water are usually some of the biggest found in the river.
Pocket water trout will not be especially shy due to the conditions that they reside in, so it is a good idea for anglers to use short stout leaders.
These slack water spots will be especially good for holding large trout who are looking for a quick meal but do not want to fight the fast current.

 Walleye fishing at its finest from the pro's at Walleyes Inc.
In the fall of the year the turbidity of the water subsides and walleyes are more visually stimulated as they see food floating by the slack water areas.
This is not to say that all walleyes see their food before they strike and in some cases they strike more out of vibration and smell than they do from visual identification.
Slack water fish can also be found by pitching jigs of 1/16 to 1/8 ounce to shoreline or cover like flooded wood or boulders.

 Tides And Currents
CURRENT DIFFERENCE---Difference between the time of slack water (or minimum current) or strength of current in any locality and the time of the corresponding phase of the tidal current at a reference station, for which predictions are given in the Tidal Current Tables.
Thus, the tide is said to be diurnal when only one high water and one low water occur during a tidal day, and the tidal current is said to be diurnal when there is a single flood and single ebb period in the tidal day.
The water level is stationary at high and low water for only an instant, but the change in level near these times is so slow that it is not usually perceptible.

Of the many myths concerning bass behavior in muddy water, the most prevalent is that bass leave a muddy environment to find clear water.
Vision is their primary sense even in muddy water, but the lateral line, which can sense vibrations over 10 feet away, becomes more important as visual range is reduced.
In muddy water, bass often hold in shallow spots near a current edge or object.

 area description
The first is characterized by a small rise in water level and increased freshwater discharge volume associated with runoff from snowmelt in the minor drainage basins in the State of Connecticut.
This is generally followed by significantly higher water levels associated with heavier snowfall amounts and snowmelt in the northern section of the drainage basin in the states of Massachusetts, New Hampshire, and Vermont.
At the beginning of the growing season in early May, when river flows are at their peak, there is no detectable salt water in the surface waters of the river estuary, regardless of the stage of the tide.
