Water Act Forum Stimulates, Educates

Thanks to Watershed Watch for putting on a forum yesterday "to discuss how NGOs can work together to move the Living Water Smart (LWS) agenda forward, and how groups can help to modernize the BC Water Act." I enjoyed the presentations, learned a lot, and was impressed with the knowledge represented by the people in the room.

The organizers are asking for input so here goes: I'm not sure if "getting groundwater in" came up much in discussion, and that's crucial, particularly in urban watersheds like the creek that I volunteer on as a streamkeeper. The focus seemed to be on sucking groundwater out, which of course is very important, but we shouldn't neglect the "letting it soak in naturally" part of the cycle.

I'm not sure if a water act can include things like impermeable vs permeable surfaces, swales, rain gardens, infiltration ponds, biofiltration, street-edge alternatives, etc., but rainwater infiltration > groundwater infiltration is crucial in urban watersheds. Otherwise too much water is dumped into creeks through rain drains (trying to reshape the debate by getting away from "storm drains") during moderate-to-heavy rains, and not enough gets into the ground to maintain base flows in long, hot, dry spells.

I know we don't want to get too detailed or prescriptive, so perhaps as part of the preamble, or guiding principles, there could be something about the permeability-groundwater issue in regard to promoting watershed-friendly development and redevelopment guidelines?
