Water Resources

This section focuses on surface and ground water resources, which includes:
Surface Waters (lakes, ponds, rivers, streams, watersheds)
Groundwater and Aquifers
Wetlands
Floodplains
Shorelands
Look at these individual sections for detailed information about each resource.

Water Resources and Wetlands Map

The five categories of water resources, listed above on and on the tabs at left, are shown on a single map in the Water Resources and Wetlands Map example. Surface waters (rivers, streams, lakes and ponds), ground water, National Wetlands Inventory wetlands and hydric (wetland) soils are individual data layers in GRANIT and are available on both GRANITView and the NH Wetlands Mapper.

Favorable Gravel Well Analysis data can be overlaid onto this map using GIS. Favorable Gravel Well Analysis (FGWA) data is available on GRANIT but not on the two online Mappers. The FGWA data is available on the Society for the Protection of NH Forests website, but would need to be generated as a graphic, clipping out the area of interest. For more information on the individual data layers, refer to Water Resources section of this guide.

Conservation lands can be included on this map to help show where existing conserved lands coincide with water resources, and opportunities to protect lands associated with water resources.

In this example, all the data layers are shown on one map; however different combinations are possible (e.g. showing NWI wetlands and hydric soils on a separate map).

Data Layers on a Water Resources and Wetlands Map may include:
> Topographic map base
> Political boundaries, transportation and utility networks
> Watershed boundaries
> Lakes, Ponds, Rivers, Streams
> Stratified Drift Aquifers
> Favorable Gravel Well Analysis (GRANIT only)
> Wellhead Protection Areas
> Public Water Supply Sources
> National Wetlands Inventory data
> NRCS Wetland (hydric) soils data
> Conservation Lands data
