This task is to develop the hydrologic and hydraulic model
for Purgatory Creek. This is part of the
Districts goal to have a district wide model.
Previous work related to this task included work to control runoff into
Lotus Lake and mitigate extreme lake level fluctuations. Tasks include developing a hydrologic and
hydraulic model, developing a plan to minimize high water events on Lotus Lake
due to outlet obstructions, and implement Low Impact Development practices to
help minimize low water events. The
budget for the 2012 effort includes the remainder from 2011 ($49,020) plus the
2012 approved amount
Modeling work continues on Purgatory Creek. Work on the section north of 212 is finishing
up. Initial work began on the section
between Valley View and 212; land survey work commenced. We presented the status of the District’s modeling
at a special manager meeting March 20, 2012.
As a result of that presentation, we presented additional model
information during the April Manager's meeting.
This included a demonstration of the modeling software.
