| == Background ==
| | This web site is an experiment with local students, residents and public agencies to see if the health of '''Botanica Park lake ''' can be improved by participative governance and information sharing between agencies. In a low carbon and resource constrained future we will all need to explore better methods of engagement and knowledge sharing to protect our communities and the natural environment. |
| * Botanica Park lake is located 16km north of Melbourne in the suburb of Bundoora.
| |
| * The lake was built in 1999.
| |
| * The lake is divided into two sections
| |
| ** Northern lake (Upper lake)
| |
| ** Southern lake (Lower lake)
| |

| === Northern lake ===

| * Stormwater enters the lake from a relatively small catchment (approximately 100 house roofs and road surfaces)
| |
| * Stormwater is treated through a Gross Pollutant Trap (GPT) which removal leaves and large litter items
| |
| * Stormwater then enters the northern lake where aquatic plants help to remove excess nutrients from the water.
| |
| * The northern lake is shallow (0.5m to 1.5m depth) and is shaded by River Red gum trees.
| |
| | |
| === Southern lake ===
| |
| * Stormwater enters the southern lake (from the northern lake) during rain events.
| |
| * A weir underneath a footbridge separates the two lakes.
| |
| * The southern lake is deeper, has steep embankments and contains large submerged stands of eel grass as the predominant vegetation.
| |
| * During rain events, water will exit the southern lake in a raised stormwater pit (underneath the decking on the east of the lake). Water travels via a Melbourne Water drain and empties into Blau Street Park further south, before entering the Darebin Creek.

| == Water for All Strategy 2020-2030 ==
| |
| * The City of Whittlesea has adopted the Water for All Strategy 2020-2030 which identifies cleaner waterways as one of five key outcomes for success.
| |
| * Many of Council’s existing water assets need to be renewed because they are not providing adequate stormwater treatment and are therefore compromising the health of local waterways.
| |
| * In addition to treating stormwater, water treatment assets improve amenity values, assist with urban cooling, and provide a safe habitat for birds, frogs and other native animals.

| == History at Botanica Park ==
| |
| * June 2017 – Botanica Park Lake Masterplan.
