Selective reservoir withdrawal system

Abstract

The invention is a water withdrawal system from a reservoir, as in a dam, for example, with a selectively adjustable withdrawal, or discharge intake, point at its core, with that intake point capable of being moved in two or three dimensions within the body of water. The invention meets the need to benefit aquatic biota by changing downstream river characteristics, such as water temperature, total dissolved gas, and mitigation of air entrainment, through obtaining the water at a specific spatial location in the upstream body of upstream water from which the downstream water is obtained, or by adjusting the characteristics of the water while it is in transit to the downstream discharge. Components may include an intake system which preferably ensures the ability to withdraw water from any location and at any depth within the body of water, like, for example, a platform (which may be either mobile or stationary), a robot arm, an intake grid system, a rail-guided intake positioning mechanism, a servocraft, or an underwater cable mechanism, components also include a water transport system, and a discharge location. System design incorporates portability, both within the body of water, and between bodies of water.

What we claim is:  
     
         1 . A selective water reservoir withdrawal system comprising: 
 a selectively-adjustable water-discharge intake point within said water reservoir; and    said intake point being adapted to withdraw water from said reservoir at desired specific spatial locations;    wherein said intake point is operatively connected to a water transport system and a discharge location.    
     
     
         2 . The withdrawal system of  claim 1  wherein 
 the adjustable intake point is movable in one dimension.  
 
     
     
         3 . The withdrawal system of  claim 1  wherein 
 the adjustable intake point is movable in two dimensions.  
 
     
     
         4 . The withdrawal system of  claim 1  wherein 
 the adjustable intake point is movable in three dimensions.  
 
     
     
         5 . The withdrawal system of  claim 1  wherein 
 the adjustable intake point is within a fixed structure within said reservoir.  
 
     
     
         6 . The withdrawal system of  claim 1  wherein 
 the adjustable intake point is movable within said reservoir.  
 
     
     
         7 . The withdrawal system of  claim 5  wherein 
 the fixed structure is a vertical crib with selectable wicket gates.  
 
     
     
         8 . The withdrawal system of  claim 5  wherein 
 the fixed structure comprises a plurality of selectively openable/closable intake panels in the up-stream surface of a dam.  
 
     
     
         9 . The withdrawal system of  claim 6  wherein 
 the intake point is the opening of a transport tube moved by a cable suspended above the surface of the reservoir.  
 
     
     
         10 . The withdrawal system of  claim 6  wherein 
 the intake point is the opening of a transport tube moved by a servocraft floating on the surface of the reservoir.  
 
     
     
         11 . A selective water reservoir withdrawal system comprising: 
 a selectively-adjustable water-discharge intake device within said water reservoir; and    said intake device being adapted to withdraw water from said reservoir at desired specific spatial locations;    a water transport system operatively and fluidly connected to said intake device and operatively and fluidly connected to a discharge location; and    wherein the water transport system comprises a water treatment system for treating or conditioning the water.    
     
     
         12 . A withdrawal system as in  claim 11  wherein said water treatment system comprises a filtration system.  
     
     
         13 . A withdrawal system as in  claim 11  wherein said water treatment system comprises an aeration system.  
     
     
         14 . A withdrawal system as in  claim 11  wherein said water treatment system comprises a water cooling system.  
     
     
         15 . A withdrawal system as in  claim 11  wherein said water treatment system comprises a bacteria-removal system.  
     
     
         16 . A withdrawal system as in  claim 11  wherein said water transport system comprises a fish addition system.  
     
     
         17 . A withdrawal system as in  claim 11  wherein said water transport system comprises a fish removal system.
