We combined decadal data (23–35 y) on nutrient concentrations for nine subarctic lakes with satellite imagery of vegetation (NDVI) to link the ongoing nutrient declines to the climate change‐induced greening of landscapes. Total phosphorus water concentrations (Total‐P) showed declining trends for all nine lakes, ranging from 1.5%–3.6%/y over the last decades. For most of the lakes' drainage areas, NDVI showed a dramatic incre...

The effectiveness of aluminum (Al) at retaining phosphate was investigated in alum‐treated Washington lake sediments. Greater than background concentrations of Al and Al‐bound phosphorus (Al‐P) were detected in three stratified lakes (Lake Ballinger, Phantom Lake, and Medical Lake) and in three unstratified lakes (Lake Erie, Cambell Lake, and Long Lake). The ratio of added Al to P (Al:Al‐P) was approximately 11:1 by weight in...
