The Palmdale Water District looks to take the next step in its years-long project to remove sediment from the reservoir behind the Littlerock Dam and increase its water storage capacity. On Monday, the Board of Directors will consider a $1.6 million contract with Aspen Environmental Group for work involved with the design, permitting and construction of the project over the next three years, with potentially two years after that. The Littlerock Reservoir Sed­i­ment Removal Project has been in the works for more than 25 years.
