The high waters have brought an unwanted guest downstream—a class 1 noxious species of fish called the oriental weatherloach. These small creatures have been causing havoc in upstream irrigation systems (first 2 left photos) and are now being found in our pipeline network, grower’s filters and domestic meters (third right photo). We have been advised their numbers will reduce as the water recedes. Please maintain your filters regularly.
