Abstract
From April of 1981 to June of 1982 a Clean Lakes Program Phase 1 Diagnostic Feasibility Study was conducted on Bear Lake, a 282 km2 (109m2) fresh-water lake located in southeastern Idaho and northeastern Utah. A portion of this Clean Lakes Program required an itemized inventory of all nonpoint sources affecting the lake's water quality.
A 16 month lake tributary monitoring program, which included the spring runoff periods of 1981 and 1982, provided data from which nutrient loading values (kg/day and kg/yr) were calculated. Analysis of these data, along with land use percentages within the Bear Lake Basin, allowed for the determination of the lake tributaries that were major nutrient contributors.
Graphs of loading values (kg/day and kg/yr) over time for the major contributors provided a means to analyze the periodicity of nutrient loading.
Management alternatives were then selected using the nonpoint source pollution inventory which included information on atmospheric inputs and septic seepage. Management alternatives were based upon technical feasibility and expected water quality improvement.
