called upon to provide for the construction of fishways over 

 the tributaries of the Connecticut, and make suitable provision 

 for the introduction of spawn or young fry into the streams 

 of the State. 



Fishways are not very expensive except over high dams 

 upon large streams. They are made of plank and usually 

 start from one end of the dam . A small gap , say four to twelve 

 feet wide and from one to two feet deep, according to the size 

 of the stream, is made in the dam, so that the waste water 

 that otherwise would flow over the dam shall pass through 

 this gap and enter the fishway, which is a trough or chute 

 descending about one foot in ten. In this trough are bars 

 that extend about half way across and are slightly inclined up 

 stream to afford resting places for the fish as they go up the 

 fishway. To make it more plain we introduce the following 

 diagram, which represents a fishway as seen from below the- 

 dam:
