This book was released on 1979 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on the visual inspection, the present general condition of the dam is considered to be satisfactory; however, the following deficiencies were noticed during the inspection and are considered to have an adverse effect on the overall safety and future operation of the dam: A dense cover of vegetation (brush, trees, and tall grass) that may conceal animal burrows, exists on the downstream face of the dam. A heavy growth of brush and small trees exist along the concrete line invert section of the discharge channel. This growth will restrict channel flow and reduce the discharge capacity of the spillway that could result in flooding of the dam channel and possible damage to the downstream face of the dam. The downstream end of the concrete lined spillway channel invert is in a deteriorated condition, as is evidenced by extensive cracking and settlement of the concrete pavement, as well as severe erosion of the pavement subgrade. Continued erosion of the spillway channel could affect the stability of the channel banks. Underseepage, as evidenced by wet, soft ground and ponded water, was observed in the vicinity of the downstream toe of slope junction with the right abutment. Uncontrolled seepage can develop into a piping condition that could lead to failure of the dam.

This book was released on 1978 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Certain deficiencies were noticed during the visual inspection and are considered to have an adverse effect on the overall safety and future operation of the dam and spillway. The upstream slope of the dam is irregular (maximum slope ratio is approximately 1v on 1.3h) beginning at a level about 12 feet below the top of the dam. Excessive irregularities of the face of the dam are indications of instability and/or erosion, both of which are considered detrimental to the safety of the dam. A substantial cover of small trees and brush that may conceal animal burrows exists on the upstream and downstream slopes of the dam. The tree roots and animal burrows can provide a pathway for lake seepage that may develop into a piping condition. The upstream slope has a grass cover to protect it from erosion by wave action. Grass cover is not considered adequate to prevent erosion by wave action for a fluctuating lake level. Loss of material can result in instability and settlement of the dam crest. A dense growth of brush and small trees obstructs the spillway crest and outlet channel.

Book excerpt: The dam and lake are located on an unnamed tributary of La Barque Creek. The dam impounds water for the purpose of private recreation for surrounding residential property owners, who are members of the Lakewood Hills Property Owners Association. Major defects, including reconstruction of the upstream slope of the dam and sealing of the lake bottom, observed during this inspection are, according to the owner, planned to be corrected sometime this summer (1978) when a contract for remedial work on the dam and lake area is awarded. The remaining deficiencies observed during the inspection are not considered of major consequence to warrant immediate remedial action.
