Fish swim via Utrecht, the Netherlands each spring to search for a spot the place they’ll reproduce. Sadly, they’ve to attend for prolonged durations of time on the Weerdsluis lock which is situated on the west aspect of the inside metropolis. The lock, constructed within the Center Ages to take care of the water stage within the canals, hardly ever opens within the spring months.
