CHANGED
Thursday, October 22nd at 4am

Soil and terrain at Waterdog Lake

Waterdog Lake is a mountain bike trail network in Bay Area, CA. Soil data at the sampled location is classified as loam. Terrain data indicates an elevation of about 404 ft, an average terrain slope of 3.4° and a predominant NE-facing aspect. Terrain slope does not measure the trail tread or its drainage features. Trails here include John Brooks Trail, Chaparral Trail and Headbanger. Loam models conditions across the network; individual trails and constructed surfaces can differ from these environmental inputs. Official closures and conditions on the ground take priority.

How these factors affect drying

SoilLoam

Loam combines drainage with water retention. Soil type alone does not establish how long this network takes to dry. The model uses surveyed water-retention values, not measured trail recovery times.

CanopyPartial 40%

Partial tree cover suggests a mix of sun and shade. Local exposure and surface conditions can vary across the network.

TerrainModerate

Moderate terrain slope is one input to the drying model. Local drainage also depends on soil and trail construction.
