- Groundwater input is likely an
important component of the Christmas
Lake water budget,
and changes in water quality over the past decades may be due in part to
changes in that input. A more
detailed model and analysis of Christmas
Lake is necessary to
better understand how both surface and groundwater inputs affect lake
levels and water quality and to develop strategies for protecting this
- The FAW concluded that the wetlands in
the southern part of the subwatershed were discharge or combination
discharge/recharge. Increased infiltration in the southern subwatershed
may be helpful in preserving that hydrology.
- As shown on Figure 17, there is a large
moderate to high aquifer sensitivity area in the northern watershed where
any stormwater should be pretreated prior to discharge to an infiltration
basin. Other areas of aquifer
sensitivity are associated with wetlands.
- Stormwater management should
be coordinated with wellhead protection plans.
