Project Description Both Minich Lake and the downstream wetlands have long been subjected to extended high water levels, which impact agricultural operations on adjacent lands. Although channelization could provide flooding relief it was expected to have negative environmental impacts. By combining the proposed channelization with two small control dams the habitat values of the area will not only be preserved but also enhanced. The Lake control dam will preserve the Minich Lake at near historical normal levels while allowing high water levels to dissipate quickly. The backflood control will provide both agricultural and wildlife benefits in virtually all years where these benefits only occur randomly at present. The dams will be small earth-filled embankments with corrugated steel pipes with steel control boxes. This project is being pursued as a cost shared between Strathcona County, the Alberta Government and Ducks Unlimited Canada.

Prime Consultant – DCL Siemens Engineering Ltd. – Barrhead Water Supply and Treatment Sub Consultancy- Sameng Inc – All aspects of Paddle River Weir Project Description The Town of Barrhead pumps water from the Paddle River to their Raw Water Reservoirs. The Paddle River Dam upstream is able to maintain a base flow of about 1 m3/s at most times of the year. Currently the Town is unable to pump water during these low flow events. As part of a current upgrading of their entire system they want to build a weir on the Paddle River that could be used to maintain higher water levels such that they could pump efficiently during low flows. Several alternatives were examined during the conceptual design and the option chosen is a Steel Sheet Pile Weir with stop log bays. The stop log bays will be used to manipulate water levels and are designed to maintain velocities low enough to allow fish passage. Consideration for small craft safety is also being incorporated into the design. Services Completed by Sub-consultant : Conceptual design of several alternatives. Hydrological modeling and analysis of existing water rights to determine availability of water. Preliminary consultations with all licensing and permitting agencies and incorporation of their requirements into design. Design of the dam and related works. Preparation of licensing applications. Services to be provided by Sub-consultant : Application to and follow up on all licences and permits. Replying to concerns raised as a result of advertising the project. Preparing tender package. Construction surveys and project management. Progress payments. Key Consultant Staff Gerald Samide, P. Eng. David Martz, P. Eng. Company Technicians. Company’s survey crew.

Pilipchuk’s Water Supply Dam Location - one dam located in SW06-57-9-W4. Project Description In order to provide domestic water for Dr. Pilipchuk, a dam was designed and constructed across a watercourse. The dam averages 4.5 m high and is approximately 40 m wide. It was designed with a full supply depth of 3.5 m. It has a 1200 mm square box drop-inlet spillway with an emergency by-pass channel. Services Provided by Consultant : Drafting survey results. Hydrological assessment of flood discharges through the dam. Computer modeling to flows through various bypass alternative designs to determine maximum water levels and design requirements. Design of the dams and related works. Preparing report and drawings for water resource licensing application. Key Consultant Staff Gerald Samide, P. Eng. Company Technician. Start-up and Completion Date Dam and related works were constructed in the spring of 2002. ________________________________________________________ South Round Hill Flood Control Project Location - one dam located in NW36-48-18-W4 and another dam located in NE25-48-18-W4. Project Description A slough downstream from where the dams are located was drained in the sixties by the Alberta Government (Round Hill Ditch Project). This project was cost shared between the County of Beaver and the Alberta Government. The purpose of the project was to provide improved drainage throughout the area. The project drained the aforementioned slough, thereby enabling the County of Beaver to construct an east west road across the slough. However the road was subject to flooding almost every year during snowmelt floods and about once every fifteen years during rainstorm floods. The slough itself is subject to flooding due to rainfall floods every five years. The cause of the flooding is mainly the low capacity in the Round Hill Ditch. In order to eliminate the flooding problem, two back flood control dams (flood storage) were constructed. These back flood dams provide enough storage to reduce the snowmelt flooding from two out of every three years to once every ten years. The rainfall flooding of the slough its elf has been reduced from once every five years to once every twenty years. Services Provided by Consultant : Preconstruction surveys required for design. Hydrological modeling to the dams to determine their effect on reducing flooding downstream and to determine design flows through the dam. Design of the dams and related works. Preparing preliminary report for cost sharing and water resource licensing application. Public relations with landowners so that they are in agreement with project. Replying to concerns raised as a result of advertising the project. Preparing tender package. Construction surveys and project management. Progress payments. Key Consultant Staff Gerald Samide, P. Eng. David Yue, P. Eng. Company Technician. Company’s survey crew. Start-up and Completion Date Tenders were called for April 28, 1989. Project was completed in the fall of 1989. ________________________________________________________ Alberta Tree Nursery Reservoir – Increasing the Amount of Storage Location - Tree Nursery is located on Horsehills Creek in Northeast Edmonton. Project Description In 1970, a small dam was constructed on Horsehills Creek to provide irrigation water for the Alberta Tree Nursery and Horticulture Centre. In July of 1995 Samide Engineering Ltd. (now renamed Sameng Inc.) was retained by Alberta Public Works to investigate (provide report and design drawings) increasing the irrigation storage capacity of the reservoir. Services Provided by Consultant: Reviewed the hydrology for the reservoir and revised the flood design discharges. Reviewed records of water used in the past to determine an adequate amount of water the Nursery should have in reservoir storage. Determined how much of the original reservoir storage has been depleted due to sedimentation. Determined that it would be necessary to raise the Full Supply Level (FSL) by 0.5 m in order to provide an adequate amount of storage. Determined that raising the FSL by 0.5 m would not result in water related problems at upstream stream crossings. Determined that raising the FSL by 0.5 m would not result in increased flooding problems upstream. Determined that raising the FSL by 0.5 m would not result in water related problems downstream of the reservoir. Determined that raising the FSL by 0.5 m would not cause problems for the operation of Alberta Hospital’s storm sewer system. Designed works to raise the FSL of the existing drop inlet spillway (opening dimensions of the new inlet into the drop inlet spillway – 6 m by 6 m). Designed works to raise the crest of the earth filled dam and modify the emergency spillway. Redesigned the thrash rack so that it would not be affected by beaver activity. Prepared a report re increasing the FSL that outlined all of the investigations and designs (report was used to amend the existing Water Resource License). Samide Engineering Ltd. (now Sameng Inc.) retained Assemheimer Engineering Ltd. to determine the structural condition of the existing concrete outlet works. Samide Engineering Ltd. retained Thurber Engineering Ltd. to provide recommendations as to requirements to the earth fill dam when the crest of the dam is raised by 0.5 m. Services Provided by Sameng Inc. (In addition to those listed above) : Provide information required by Alberta Environment to amended existing Water Resource License. Prepare contract documents (specifications and drawings). Preconstruction surveys required for design. Computer routing of flood hydrographs through the dam. Replying to concerns raised as a result of advertising the project. Construction surveys and project management. Progress payments. Key Consultant Staff Gerald Samide, P. Eng. Company Technician.
