NUTRIENT LOADINGS TO THE SALTON SEA: PAST, PRESENT, AND THE FUTURE
 
The Salton Sea, the largest lake in California, has received agricultural, municipal and industrial wastewaters rich in N and P almost since it was formed as a result of an engineering accident in 1905. Occupying a below sea level depression and lacking an outlet, it has become increasingly saline (now 43 g/L) and increasingly eutrophic (avg Secchi disk, ca. 1.3m), with a number of attendant problems such as massive fish and bird dieoffs. The binational watershed includes large amounts of agricultural land but also several cities, including Mexicali and Palm Springs. Changes in N and P loadings and in-lake concentrations between 1968-69 and 1997-98 are interpreted in terms of population growth, urbanization, and other changes. P and N loadings have increased but water column N and P values have changed little. The sediments are loaded!
