1 5 This section would be improved with a description of the surface water contribution from the various<br />

forested area within the <strong>Middle</strong> <strong>Rio</strong> <strong>Grande</strong>. This information is already provided in Tables 5‐4 and 5‐5<br />

and in Figure 5‐8, and could be summarized in a bullet. Specifically, add "Streams originating in forested<br />

mountains within the <strong>Middle</strong> <strong>Rio</strong> <strong>Grande</strong> region are another source of surface water. These forests are<br />

primarily National Forest System lands, but also include many Tribal reservations, Bureau of Land<br />

Management and National Park Service holdings, as well as lands managed by New Mexico State Land<br />

Office and Departmen of Game and Fish. The most significant forested areas in the <strong>Middle</strong> <strong>Rio</strong> <strong>Grande</strong><br />

region are in the Jemez Mountains. The East Mountain area also contributes to water supply, through<br />

streamflow, springs and mountain front recharge."<br />

2 5.1.2 Recent Climate Studies would be improved with a brief description of the effect of climate changes on<br />

wildfire timing, duration and severity, as this has a direct impact on forested areas that are important<br />

water sources. This data is already compiled in BOR Upper <strong>Rio</strong> <strong>Grande</strong> Impact Assessment<br />

http://www.usbr.gov/watersmart/wcra/reports/urgia.html. Specifically add a bullet on page 15 "Drought<br />

and higher temperatures lead to tree‐stress and moisture‐deficit, making forests more vulnerable to highseverity<br />

wildfires, leaving burn scars that repel rainwater, and affecting water supplies thorugh ash‐laden<br />

floods and debris flows." The citation is Llewellyn and Vaddey, 2013. Upper <strong>Rio</strong> <strong>Grande</strong> Basin Impact<br />

Assessment: Westwide Climate Risk Assessment. Bureau of Reclamation."<br />

3 5.3.1 <strong>Regional</strong> Hydrogeography or Section 5.3.2 Aquifer Conditions would be improved with a clearer<br />

description of the role of mountain front recharge to groundwater. This is important because of the<br />

possibility that these mountain fronts could undergo an ecological type conversion and/or burn in a highseverity<br />

wildfire, potentially changing infiltration and groundwater recharge. Such as: "Recharge along<br />

the mountain front of the Sandias is an important contributor to groundwater, especially from the Sandia<br />

Mountains." But Katherine Yuhas may provide much better language and if she does please replace this<br />

with hers.<br />

Technical<br />

4 5.4 <strong>Water</strong> Quality Assessment has a paragraph on impacts that does not include wildfire impacts, specifically Technical<br />

post‐fire, when rain falls on severely burned areas. The findings of a recent report by the USGS New<br />

Mexico <strong>Water</strong> Science Center analyzing wildfire potential and the probability of post‐fire debris flow for<br />

the Sandia and Manzano Mountains should be incorporated http://pubs.usgs.gov/sir/2014/5161/ . In<br />

addition, a study using the same methodology for the Jemez Mountains will be published in April 2016<br />

and could be incorporated before the <strong>Regional</strong> <strong>Water</strong> <strong>Plan</strong>ning deadline. Specifically add "Another<br />

problem contributing to water quality impairment is runoff, flooding and debris flows from catastrophic<br />

wildfire." (A.C. Tillery, J.R. Haas, L.W. Miller, J.H. Scott, M.P. Thompson. 2014. Potential Postwildfire<br />

Debris‐flow Hazards: A Prewildfire evaluation for the Sandia and Manzano Mountains and Surrounding<br />

Areas, Central New Mexico. USGS. SIR 2014‐5161.)<br />

Please also consult with Page Pegram, ISC, as the source for this sentence: "In some cases after the 2011<br />

Las Conchas Fire, sediment mobilized after wildfire in a tributary canyons was substantial enough to<br />

create a plug of debris that has blocked the <strong>Rio</strong> <strong>Grande</strong>."<br />
