What are the summer practice questions for the Northeast Corner?

Fortunately, Y Creek still has some stretches of river channel with natural variation! With combinations of different water depths and flow rates, all kinds of aquatic life - those that like the bottom, those that need more oxygen, those that graze on algae, and those that hunt - all coexist here in one place. Watching these fish, shrimp, and crabs that come in from the ocean for different reasons such as growth or reproduction, having to live densely mixed together with freshwater fish in this half-enclosed stretch of creek, coming from all directions and having to pull together through the same boat (here they might even exchange children to eat), it actually feels a lot like Taiwan's situation half a century ago.

Summer Practice Questions: How do we restore the environment's ability to retain water?

This is a survival adventure! A not-too-far distance can get you into a suitable mid-to-upper reaches environment, but you need a river channel that is free of pollution and blockages, and you also have to escape the predators that open their big mouths to hunt in the wide-open downstream channels, passing through one barrier after another. Yet summer drought has become a new test factor. Neighbors compete with neighbors for water, and the agricultural and industrial sectors compete with each other, let alone the aquatic creatures that are most easily overlooked!

Fortunately, in just this short 200 meters of Y Creek we could still see more than 20 kinds of fish. Only in the small creeks on the east side of Taiwan, where the ocean presses right against the mountains, is there such a characteristic that can accommodate so much abundant life from so many different sources. However, the Daxi River in Toucheng North has already been affected by tap water extraction plus changes from a project more than two years ago. What was originally a river corridor with extremely high migratory fish diversity has already dried up into a disconnected flow of up to 100 meters long! How to restore the environment's ability to retain moisture and conserve water, preserve river channels with multiple types of variation, and even incorporate the ecological base flow needs into scheduling and regulation, so that fish and crabs and farmers can all safely get through the thirst before the typhoon - this is the increasingly severe summer practice question waiting to be challenged in the Northeast Corner!
