Characteristics of Lake Mendota (ME) and Crystal Bog (CB) Lake.

Feature	Mendota	Crystal Bog
Location	46.01°N, 89.61°W	43.10°N, 89.41°W
Surface area (ha)	3938	0.5
Mean depth (m)	12.8	1.7
Max depth (m)	25.3	2.5
Trophic status	eutrophic	dystrophic
Shoreline development	high	low
Total phosphorus (μg L-1)	109.5	18.2

We present long-term averages from routine sampling by the NTL-LTER (1981–2010 for CB and 1995–2010 for ME). Mean wind speed data are from high-resolution data collected 2005–2011 for both lakes.
