Evaluation of methods and uncertainties in the water budget

Water budget studies of Mirror Lake aim to measure hydrologic components interacting with the lake as accurately as possible. However, measurements of water budget components are subject to some degree of uncertainty. This chapter describes the methods used to quantify water budget components of Mirror Lake in detail. It examines uncertainties in precipitation values, monthly evaporation, water flows, and exchange with groundwater. It shows how those values were derived, including the assumptions that went into the calculations and the uncertainties inherent in the values.
