Floods of October 1986 in southcentral Alaska
R. D. Lamke, B. B. Bigelow
1987, Open-File Report 87-391
Heavy precipitation associated with a large storm system resulted in major flooding in several areas of south-central Alaska during October 10-12, 1986. Flooding was particularly severe in the Seward area of the Kenai Peninsula and in tributaries to Susitna River from Telkeetna downstream. Flood damage has been estimated at $20...
