| Abstract |
Major differences were found in the distribution of lake types between areas of the United States. Drainage lakes were most common in the Northeast and West. Seepage lakes were common in some areas of the Upper Midwest (59% of the lakes in Northcentral Wisconsin) and Florida (66%). Seepage lakes represented 18% of the lakes in the West. Seepage lakes in the Northeast had ANC values similar to drainage lakes whereas seepage lakes in the Upper Midwest and Florida had lower ANC compared to drainage lakes. Reservoirs in all regions had the highest median ANC and Ca2+. Hydrologic residence times were two to three times shorter in the Northeast than in the Upper Midwest, but DOC was inversely related to residence time in both areas. Acidic drainage lakes (ANC |
