Each recreation trip or visitation has an associated set of expenditures. The composition of these expenditures for typical trips of single day or multiple days (Table 1) is based on a survey of Storm Lake and Rock Creek Lake during the 2002 season. Applying these averages to the lake visitors in the above table results in the estimated spending figures in Table 2.
This level of spending is linked to other economic activity in the region as the initial expenditures are re-spent on goods and services in the regional economy. These multiplier effects are estimated with an Input-Output model for the region and are summarized in Table 3.
