The dam was reconstructed in 1922 to include a 200-foot-wide stability berm with a top elevation about 30 feet below the dam crest and a series of loose rock internal drains.

Without the comprehensive review, the minor dam crest depression and embankment movement might have continued to be brushed aside as a normal nuisance condition, which might have paved the way for another, and potentially more devastating, slope failure at Marshall Lake Dam. if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[580,400],'fishingworks_com-medrectangle-4','ezslot_2',118,'0','0'])};__ez_fad_position('div-gpt-ad-fishingworks_com-medrectangle-4-0'); Plans for the Construction of an Earth Embankment Along the Downstream Face of Marshall Lake Dam.

Though the peak reservoir level reached within 3 feet of the dam crest during the rain event, the 1921 slope failure didnt lead to an uncontrolled loss of the reservoir because the 48-inch-diameter outlet works flow capacity was sufficient to lower the reservoir at about the same rate as the embankment settlement was developing. Twenty First Biennial Report. Boulder, All rights reserved. The underlying problem is, The Laramie claystone has poor foundation strength characteristics because it is highly plastic and slickensided, with relatively high in-situ stresses. Similar to the embankment enlargements, the construction is suspected to have followed the hydraulic fill method since that was the state of the practice at that time, though this has not been confirmed. 2023 Marshall University. Sunset Park Lake in Longmont had a large diving tower and was a popular spot for swimming and Fourth of July celebrations (complete with fireworks) in the 1920s and 1930s. This slope failure was notably less significant than the previous failure in this location, dropping the dam crest by 2 feet in a 200-foot-wide reach, but was sufficient to prompt extension of the 1922 stability berm to the south of the outlet works alignment. OK. Similar to the 1921 failure, the 1942 failure occurred following a moderately heavy rain event; however, no association between the rain and the failure is made in the historical records.
