• HEC-HMS and HEC-RAS models for Lower Pecos Red Bluff Reservoir HUC8 (13070001) watershed are split into five model domains: LP_Upper, LP_Lower, Salt Draw, Toyah and Imperial Domains. • HEC-HMS and HEC-RAS models for LP_Upper and LP_Lower, model domains are included in this folder. • From future model maintenance and updates standpoint, models for other three domains were included with the respective HUC8 watersheds for Salt Draw (13070004), Toyah (13070003) and Landreth Monument Draws (13070007) watersheds. • This approach was used to avoid creating multiple copies of same model and to reduce storage requirements.
