Essentially interim instream flow standards reduce the use of water for non-instream uses, particularly under low-flow conditions. “We really seek to prioritize public trust uses over non-public trust uses and IIFS are one tool that helps us do that,” state hydrologists said.

Shaun Jeszenka, owner of Frontier Anglers in Dillon, hopes to pursue a statewide ballot initiative that would establish minimum instream flows for Montana rivers.

Increasingly, Colorado is designating junior waterrights to streams themselves as rivers and drought continues to shrink water supplies.

The Yellow River Basin is of great significance to China's economic and social development and ecological security. The Yellow River Basin is not only an important ecological barrier but also an important economic zone. In this paper, natural hydrological conditions were taken as a reference, a habitat simulation model of the key sections of the Yellow River was constructed based on the MIKE 21 model, and an ecological water requirement assessment method for river ecological integrity combin...

At the time western water codes developed, these goals were seemingly in harmony—rewarding those who needed the water and invested in infrastructure for water use with rights that were enforceable against subsequent appropriators. Over the...
