Book Description
The Grand St. Marys shore flood problem is caused by the inability of the 10.6-mile long westerly outlet channel to discharge sufficient flood flows to keep pace with inflow to the lake during peak periods plus the effect of wind setup and wave runup on low-lying developed areas when lake levels are high. Beaver Creek flood problems are caused by a combination of a limited flood control capablility of Grand Lake St. Marys, poor surface drainage, low stream gradient, constriction to flow, and high stream stages for a long period of time which cause inadequate outlet conditions for numerous artificial agricultural drains. Lake water quality has been declining in recent years. Four separate water quality problems have been identified as causing the deterioration. Bacterial contamination from human resources threatens body contact recreation, particularly in areas of greatest development. The rich nutrient content of the lake results in excessive algae and suspended sediment, resulting in unattractive conditions for recreators. Accumulation of sediment, eroded from upland areas, and unprotected shoreline have reduced the lake depth. A range of structural and nonstructural flood damage reduction measures were examined. Nonstructural measures investigated for Beaver Creek are not viable solutions because of the agricultural character of the flood plain. Structural measures considered for Beaver Creek including detention basins, diversion, clearing and cleaning, channel improvements, and agricultural levees were determined to be economically infeasible.

Book Description
Nonstructural flood plain management measures generally will not improve the flood problems for existing structures on the south shore, but regulations adopted by local governments either voluntarily or as required by participation in the flood Insurance program could be used to reduce damages to future development. Structural measures such as groins and shoreline levees (dikes) are not perceived to be economically feasible. Fixed breakwaters can be effective in reducing shoreline flooding and erosion, but economic benefits are derived primarily from the potential for increased visitation and not from flood damages reduced. Lake water quality problems related to nutrient and algae control appear better resolved through reduction of nutrient loads to the lake and in particular control of agricultural and livestock waste sources rather than by in-lake treatment approaches. Emphasis should be placed on the control of erosion and critical soil loss areas in the watershed and unprotected shoreline areas. An extensive lake-wide dredging program, besides being cost prohibitive, would result in no significant improvement in water quality or flood control storage. In-lake dredging of selected near-shore zones as is currently being performed should be contained for improving lake access and boater safety, public land development, and to keep pace with the current rate of sediment accumulation and redistribution.
