Iowa Lakes Valuation Project



Lake Keomah   


Iowa lakes have great value to the citizens of the state. In the process of using lakes for fishing, boating, swimming and enjoying other outdoor recreation, Iowans also spend money that benefit local economies. During the 2002-2005 period, Lake Keomah averaged 49,526 visitors annually. They spend an average $3.29 million annually which in turn supports 65 jobs and $0.88 million of labor income in the region.

Multiple Day Trips, 2002 4,657
Total Trips, 2002 49,526

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.
