UrduHistorically, Lake Okeechobee was thought to be impaired only by phosphorus, focusing efforts on reducing agricultural runoff. However, new comprehensive sampling across the Lake Okeechobee Waterway and its connected estuaries shows that toxic algal blooms also are driven by rising nitrogen levels from human waste and urban runoff. Increased nitrogen, worsened by extreme rainfall, significantly fuels bloom severity. Findings underscore the need for integrated nutrient management and improved wastewater treatment to protect the lake and its estuaries.

Why isn’t Colorado’s snowpack ending up in the Colorado River? New research suggests the problem might be the lack of spring rainfall
The Colorado River and its tributaries provide water for hydropower, irrigation and drinking water in seven U.S. states and Mexico. But since 2000, water managers have struggled to predict how much water will come from the snowpack. The problem lies with the lack of rainfall in the spring, according to new research from the University of Washington.
